Introduction

Recent events such as floods, bushfires, and pandemics have demonstrated communities’ reliance on volunteers (Lai & Wang, 2022; O’Halloran & Davies, 2020). From major crises to individual incidents, it is often volunteers who provide help on people’s worst days. For instance, there are 186,000 emergency responders and firefighters in Australia and 90% of them are volunteers (Productivity Commission, 2022). Furthermore, in 2018, Lifeline volunteers answered 739,481 phone calls from those who needed crisis support (Lifeline Australia, 2019). Considering societies’ reliance on the response, recovery, and support services provided by volunteers, it is alarming to note that participation in formal volunteering (i.e. performing voluntary, unpaid work through an organisation) has been steadily declining. From 2014 to 2020, formal volunteering hours dropped by 34% in Australia (ABS, 2021). A similar declining trend has been observed in the USA (Fernandez & Alexander, 2017; Schreiner et al., 2018) and Europe (Curran et al., 2016; Qvist et al., 2018). This decline suggests a significant fiscal cost for societies to replace unpaid labour. For organisations across various nations that rely on volunteers, it adds challenges as pressure mounts to cope with the lost workforce. As natural disasters increase in frequency and severity, it is paramount for volunteer-involving organisations to attract and sustain vital volunteer workforces.

The volunteering landscape is shifting dramatically. The COVID-19 pandemic, economic pressures, shifting employment ecosystems, and the prioritisation of lifestyle, family and work commitments are leading to an increased preference for short-term or informal volunteering (McLennan et al., 2016). This poses significant challenges to organisations that rely on long-term volunteers. However, there are things that can be done to alleviate the pressure arising from declining numbers of regular, long-term volunteers. One way is to unpick volunteer motivation, which is fundamental for attracting and retaining volunteers. Another way is to ensure that volunteers do not stop volunteering due to issues that could have been prevented by volunteer-involving organisations, such as poor leadership (Lantz & Runefors, 2020). When it comes to motivating and retaining members, there is a raft of research that highlights the essential role of leadership in the paid employment context (Cheong et al., 2019; Kaiser et al., 2008; Naile & Selesho, 2014; Tse et al., 2013). For example, leaders can shape the work environment by fostering a culture of collaboration and trust and by providing guidance and opportunities for employee development. In turn, this can lead to positive organisational outcomes such as increased work engagement and retention (Mendes & Stander, 2011). However, less attention has been paid to the uniqueness of leading in ways that might motivate and sustain members who are volunteers. Leadership studies within mainstream management research mostly discuss or examine leadership on the underlying assumption that followers work to be paid, which, inarguably, does not apply to volunteers. Volunteers may not be paid, but there are immense economic implications to volunteering. The replacement costs associated with replacing volunteer labour with paid labour are immense. In Australia, volunteers contributed 489.5 million hours through organisations in 2020 (ABS, 2021), which, even at minimum wage and forging oncosts would equate to more than $9 billion. Similarly, the annual contribution is estimated to be 167 billion USD in the USA (Gui et al., 2022).

The fact that volunteers are not paid, means the conventional lever of remuneration is absent from the toolboxes of leaders and managers of volunteers. This suggests that leaders of volunteers must exhibit especially nuanced leadership when managing volunteers and leading organisational success (Jaeger et al., 2009). Having established our reliance on volunteers and the fact that volunteer numbers are dropping at an alarming rate, it is imperative that we take steps to better understand how leaders and managers can better attract, motivate, and retain volunteers.

Integrating the Volunteer Functions Inventory and Leadership Theories

This article distils leader behaviours that might be most effective in motivating people to engage in unpaid work. We do so by integrating extant leadership literature with the widely recognised framework, the Volunteer Functions Inventory (VFI, Chacón et al., 2017; Clary et al., 1998), which describes the internal drivers that motivate people to volunteer. Unlike reactive and spontaneous helping behaviour, volunteering is a proactive, planful and goal-directed helping behaviour (Wilson, 2012). Functional theorising, such as the VFI, posits that people volunteer to fulfil certain psychological functions (hereafter, volunteer motivations. Clary & Snyder, 1991). By using the VFI as a lens to examine leader behaviours, we can clearly illustrate how leaders can effectively leverage different volunteer motivations.

The VFI enumerates six functions that volunteering fills for people: values (volunteering to express personal values), understanding (volunteering to learn), career (volunteering to advance their career), social (volunteering to respond to social expectations), enhancement (volunteering to enhance self-esteem) and protective (volunteering to reduce negative feelings). It is suggested that an individual may volunteer to satisfy more than one of these functions and that multiple motivational functions may impel volunteer initiation, participation, and continuation (Stukas et al., 2009). For example, an individual might have initially become a volunteer to fulfil their career motivation, believing that volunteering would help them gain employment. Over time, the individual may become more actively engaged in the social side of volunteering, forming meaningful relationships with other volunteers, which would then serve to satisfy the individual’s social motivation. Regardless, understanding what leader behaviours might trigger which of the six volunteer motivations may offer some insights into the role of leadership in motivating and retaining volunteers.

There is a well-evidenced proliferation of leadership theories (Alvesson, 2020; Antonakis, 2017; Dinh et al., 2014; Meuser et al., 2016) and there is a preponderance of research focussed on understanding why people are willing to do unpaid work (Hustinx et al., 2010; Ma & Konrath, 2018). But, until now, there has been no comprehensive look at how scholarly leadership knowledge may be applied to leading unpaid workers. Leading volunteers is an apparent paradoxical challenge. This is because the motivating effect of leadership becomes more important when there is no monetary incentive. However, the same fact that volunteers are not bound by the dependence on pay and may cease volunteering at any time can make leaders reticent to exert leadership authority (Jaeger et al., 2009). Likewise, even when volunteers and paid employees are working towards the same objectives, they might perceive the workplace differently (Fallon & Rice, 2015). Other studies also underscored those managerial practices need to adapt to the uniqueness of volunteers in contrast to paid employees (Studer, 2016; Vieira Da Cunha & Antunes, 2022).

A Conceptual Map for Leading Volunteer Motivations

As a springboard, this article draws linkages between leader behaviours and specific volunteer motivations through a narrative review of leadership literature and volunteer literature. In each of the following six sections, we elucidate and define the distinct focus of the six VFI functions, we then identify and discuss relevant leadership theory to distil specific leader behaviours that could satisfy or trigger the corresponding motivation. The leadership theories we draw upon are considered foundational within mainstream leadership journals, which, to date, have paid little heed to the volunteering sector. The hope is that this initial integration sparks further synergies between leadership research and the unique context of volunteering organisations. The resulting framework, outlining all six motivations and corresponding leader behaviours is illustrated in Table 1. By completing this integration, this article serves as a conceptual map, providing scholars and practitioners with a novel and succinct way to navigate the plethora of leadership theories to identify discrete leader behaviours that might motivate volunteers and sustain the vital unpaid workforces we rely on. Given the increasing reliance on volunteers (Lai & Wang, 2022) and the crucial role of good leadership in keeping volunteers volunteering (Veres et al., 2020; Vieira Da Cunha & Antunes, 2022), we introduce a new perspective that may yield cascading contributions to both management and volunteer research. Implications for practice and avenues for future research are discussed.

Table 1 Summary of discussed motivations and suggested leader behaviours

Values–Expressing Oneself Through Being Prosocial

By definition, volunteer work is done for the sake of helping others (Wilson, 2012). The values motivation refers to people’s deep-held belief in helping others and supporting causes that are important to them (Clary et al., 1998). Although this motivation is often related to one’s altruistic attitude, it can also be interpreted as the opportunity for one to express themselves through being prosocial (i.e. actions that benefit others directly or indirectly through other causes, Butt et al., 2017). Unlike changing personality, triggering someone’s motivation to be prosocial may be achievable (Aknin et al., 2018). For example, the founder of the Student Volunteer Army, Sam Johnston, motivated 10,000 people to volunteer for those who were affected by the Christchurch earthquakes in 2011 (The New Zealand Herald, 2011). This could be because of his ability to arouse prosocial motivation, or because people tend to offer help when witnessing prosocial behaviours (Sullivan, 2019). This implies that the values motivation could be triggered by leadership. With regards to motivating others towards organisational missions that are service-oriented, transformational leadership and servant leadership are the most naturally aligned approaches (Schwarz et al., 2016; Wright et al., 2012).

Prior volunteer studies have suggested the more volunteers perceive the meaningfulness of their work, the more they are satisfied with their experience (Dwyer et al., 2013; Faletehan et al., 2021), which in turn, may improve their intention to remain (Chacón et al., 2007). The meaningfulness of volunteering often reflects the goals or missions of a volunteer-involving organisation. For instance, the meaningfulness of volunteering with fire and emergency services might be derived from the opportunity to protect the lives and assets of communities. Transformational leadership is known for articulating organisational goals to arouse the motives of others (Bass & Bass, 2009). If a leader can articulate the differences volunteers can make through achieving inspiring organisational missions, it may arouse their motivation to volunteer and even attract others to join the organisation.

Unlike leaders of paid employees, leaders of volunteers may possess less legitimate power to leverage volunteers to work towards organisational goals. Servant leadership is praised for its approach of putting followers’ values ahead of organisational values and conceptualising organisational values to fit individual needs (Eva et al., 2019). If a leader helps volunteers see how the organisational values are aligned with their own, it may also motivate them to continue volunteering. Additionally, servant leadership is known for acting with ethical standards and creating a shared value through their care for others, empathy and humility, which is relevant to influencing others to act on the ethos of volunteering (Veres et al., 2020). This further highlights the potential link between leader behaviours derived from servant leadership and the values motivation.

Understanding–Learning Through Volunteering

The understanding motivation refers to people seeking to gain new knowledge through volunteering, such as learning new skills or obtaining different perspectives (Clary et al., 1998). Learning through volunteering may take place both formally and informally (Schugurensky & Mündel, 2005). Formal learning refers to structured programs for members to acquire knowledge and skills (Garavan et al., 2002). Though volunteer work is often assumed to be simple tasks, training is often provided to volunteers to help them become ‘helpful’ (Overgaard, 2019). Newton et al. (2014) have found that volunteers who perceived more formal learning opportunities from their organisation showed higher levels of commitment and intention to stay. Informal learning refers to unplanned learning that results from experience (Garavan et al., 2002). For example, volunteers may improve communication skills through more social interactions (Jones, 2000) or gain a deeper understanding of social issues through volunteer service (Parker et al., 2009). When it comes to facilitating learning, and thus satisfying the understanding motivation, it is useful to draw in developmental leadership, a set of leader behaviours focussing on the development of organisational members (Zhang & Chen, 2013).

Developmental leadership is an emerging concept derived from a specific dimension of existing leadership theories, such as transformational leadership and path-goal theory, where leaders engage in behaviours that aim to improve members’ work-related knowledge (Delle & Searle, 2022). This is because, in order to maintain organisational competitiveness, leaders are often expected to develop employees’ capabilities to innovate, adopt changes and improve performance (Gilley et al., 2011; LeBrasseur et al., 2002). Extant research has suggested that this type of leadership can have a positive effect on employees’ learning and development through direct structural change and indirect influences (Ye et al., 2019; Yukl, 2009). For instance, leaders can help to increase the perception of psychological safety that allows employees to try new things or learn from errors. The developmental leadership model proposed by Gilley et al. (2011) and Wallo’s (2008) findings on leader behaviours that facilitate learning may help to illustrate three roles, or sets of behaviours, that a leader may engage in to fulfil or trigger a volunteer’s understanding motivation.

Firstly, leaders can act as educators, who teach how things should be done, clarify expectations (Wallo, 2008), and provide feedback for improvement (Gilley et al., 2011; Lopez-Cabrales et al., 2017). These behaviours may be relevant for volunteer tasks that require specific competencies or are potentially difficult, such as caring for elders with dementia, which as described in Tingvold and Olsvold’s (2018) study, was often far from one’s assumption that volunteer work would just be rewarding and simple. Secondly, leaders can act as supporters, who maintain a good learning environment (Gilley et al., 2011; Wallo, 2008) and create learning opportunities (Gilley et al., 2011). For example, fostering a fear-free environment where volunteers would feel encouraged to learn and try new things; allowing volunteers to explore their strengths by alternating tasks, or introducing volunteers to organisational stakeholders to improve their interpersonal skills (Schugurensky & Mündel, 2005). Thirdly, leaders can act as motivators, who promote learning and seize opportunities for volunteer development (Gilley et al., 2011). For example, leaders may emphasise the informal learning benefits that volunteers may get from working alongside others (Eraut, 2004).

Career–Increasing Employability Through Volunteering

The career function motivates people to volunteer as a way to help with their career paths, such as adding experiences to their resume, exploring career options or networking (Clary et al., 1998). Volunteer studies have shown that career motivation was more often observed in students, people who are unemployed, and people who are preparing to compete in the job (Gage & Thapa, 2012). People with this motivation seek career-related benefits from volunteering to increase their employability (Van Der Sluis & Poell, 2003). With regards to how leaders may help volunteers to perceive their employability can be improved through volunteering, developmental leadership suggested in the previous understanding motivation is again relevant.

In the same vein, as developmental leadership helps organisational members to build their capabilities, it also improves their job-related skills. In the study of Rafferty and Griffin (2006), they found that developmental leadership is positively related to employees’ perceived career certainty, satisfaction and commitment, in which career certainty is a concept closely related to employability. The developmental leader behaviours examined by Rafferty and Griffin (2006) are close to mentoring and coaching, whereby leaders teach job-related skills and provide feedback to improve job performance. In the case of volunteering, if the tasks require skills or experiences that align with volunteers’ desired careers, leaders can incorporate opportunities to practice said skills or experiences into volunteering activities, therefore supporting the volunteers’ career motivation.

Developmental leadership, as expanded by other studies (e.g. Gilley et al., 2011; Larsson, 2006; Yukl, 2012), also includes providing challenging assignments and career advice. In volunteering, examples of challenging assignments can be for volunteers to organise a fundraising event or lead a project with the support of organisations, which can add achievements to their resumes. But this may first require leaders to identify volunteers’ strengths and weaknesses and give encouragement to help them feel comfortable taking up challenging roles (Larsson, 2006; Palanski & Vogelgesang, 2011). Moreover, as suggested by Gilley et al. (2011), developmental leaders also maintain favourable external networks to help organisational members make critical contacts. This may be particularly relevant for those who are motivated to volunteer because they see volunteering as a pathway to employment. For example, leaders of volunteers can help to identify suitable training opportunities or introduce key contacts when volunteers are entering the job market. Additionally, leaders may seek to cooperate with job centres or government-supported agencies to promote volunteering as a pathway to employment (Rochester et al., 2009).

Social–Gaining Social Rewards Through Volunteering

The social motivation encompasses an individual’s concern for their relationships with others and the expectations from their social circles (Clary et al., 1992, 1998). In other words, one may volunteer to strengthen their social relationships (e.g. volunteering to spend more time with friends and family) or as a result of the normative influence (e.g. volunteering to make others like them and think highly of them). Studies have shown that these social factors can make volunteers become more engaged in volunteer activities (Mcdougle et al., 2011) and stay within the same volunteer group longer (Ryan et al., 2001). In the study of Kragt et al. (2018) on emergency services volunteers, camaraderie or belonging to a team is one of the most common reasons for becoming a volunteer. This suggests that volunteering provides social-related rewards, such as obtaining a social identity, feeling a sense of belonging and receiving peer recognition (Jessen, 2010). Therefore, we suggest the aspect of team-based leadership research that focuses on team member cohesion can be relevant.

Team leadership studies emphasise the main task of a team leader is to maintain or improve the outcome of teamwork, rather than the sum of individual work outcomes (Zaccaro et al., 2008). A team leader can do so through various functions, one of which is to maintain team cohesion (Hill, 2019). Improved team cohesion creates more opportunities for members to receive social rewards (Gu et al., 2021), and it may grow their willingness to engage in helping behaviours (Liang et al., 2015), which directly supports the fulfilment of the social motivation in volunteering. A team leader may improve team cohesion by establishing team norms, or clear guidelines and standards for behaviours, such as being fair and consistent (Hill, 2019; Zaccaro et al., 2001). When applied to volunteer settings, these team norms can help volunteers from diverse backgrounds with different perspectives understand how to behave agreeably within their group. According to Hill’s (2019) team leadership model, it is also suggested that leaders should support individual members who have difficulty blending in with others. This is in line with fulfilling the social motivation by removing the barriers for volunteers to strengthen their social relationships.

Leaders can also promote teamwork to create opportunities for volunteers to establish their social identity and receive peer recognition, thereby satisfying the social motivation. This is because teamwork naturally creates more interactions between members, and a common goal can allow group members to perceive a sense of collective identity and obligation (Gu et al., 2021; Salas et al., 2000). This is in line with the study of Haski-Leventhal and Cnaan (2009) on the role of the group process in promoting volunteerism, in which they suggested that collective identity allows volunteers to feel a sense of belonging and receive peer recognition (Haski-Leventhal & Cnaan, 2009).

Protective–Dealing with Negative Feelings Through Volunteering

The protective motivation refers to the need for one to keep themselves from negative feelings, and volunteering work can serve as a remedy for personal issues, loneliness, guilt, or feeling incompetent (Clary et al., 1998). Studies have shown that volunteering helped widows feel less lonely (Carr et al., 2017) and improved the well-being of elders (Chi et al., 2021). Studies on conservation stewardship suggested that volunteering helped volunteers to relieve their sense of guilt from the problems that humans have caused to the environment (Asah & Blahna, 2012). With regards to helping volunteers address their adverse feeling through volunteering, we suggest both supportive leadership and task-oriented leadership can be helpful.

Leaders may set the tone and co-create a desirable environment with others through what they say and do (Kaiser et al., 2008). Supportive leadership describes when leaders attend to the well-being and needs of an individual member, make the work environment pleasant, and build quality relationships (Yukl, 2012). Khalid et al. (2012) have found that supportive leadership helps to reduce stress, anxiety or other negative attributes of employees. This suggests that supportive leadership may be suitable for enhancing the protective mechanism that one may be seeking from volunteering. An environment where volunteers can feel welcomed, supported, and safe to share their concerns may help those who are coping with loneliness or negative feelings. In the volunteer study of Waikayi et al. (2012), they also suggested that leaders’ supporting behaviours may contribute to volunteer retention.

Task-oriented leadership refers to when leaders’ main focus is on achieving organisational goals, in which leaders engage in behaviours such as providing structure, facilitating training to improve members’ competencies and aligning members’ roles with their skills (Yukl et al., 2002). The relevance between task-oriented leadership and the protective motivation is put forward according to the findings of Zievinger and Swint (2018), which suggested the possibility that the more volunteers receive directions and training, the more they could distract themselves from their personal issues. This implies that task-oriented leader behaviours are likely to enhance the protective mechanism of volunteering. Additionally, task-oriented leadership is also shown to have a positive effect on members’ perceived group efficacy and work outcome (Tabernero et al., 2009). In the case where volunteers care deeply about helping the disadvantaged or environmental conservation, task-oriented behaviours may help them feel confident that the organisation is effectively utilising their contribution.

Enhancement–Feeling of Increased Self-esteem and Empowerment

The enhancement motivation pertains to one’s desire for psychological growth (Clary & Snyder, 1999), whereby volunteering can contribute to self-development and self-esteem and fulfil the desire to feel important and needed (Clary et al., 1998). Contrary to people with the protective motivation, who seek to feel ‘better from the negatives’, those with the enhancement motivation strive to feel ‘good about themselves’. Studies have found that the enhancement motivation is positively related to volunteer satisfaction (Dwyer et al., 2013) and intention to keep volunteering (Newton et al., 2014), which implies that triggering the enhancement motivation could keep volunteers volunteering. Several outcomes derived from volunteering can fulfil one’s enhancement motivation, such as feelings of autonomy, a sense of achievement, finding value in voluntary service, being asked to help, and being recognised for their contribution (Vecina et al., 2013). Many of the above are closely related to the concept of empowerment, which refers to “the perception by members that they have the opportunity to help determine work roles, accomplish meaningful work, and influence important decisions” (Yukl & Becker, 2006: 210). Amongst the various leadership styles that previous leadership research has established, participative leadership is the style that is most often thought to be a major source of empowerment (Huang et al., 2010).

Participative leadership is seen when leaders invite members’ suggestions before making decisions and share responsibilities (Arnold et al., 2000). These behaviours can thus make the members feel empowered through feeling a sense of control and competency, especially when the collective decision has led to a positive result (Yukl & Becker, 2006). It is also suggested that participative leader behaviours can help provide clarity to members about the goals to be achieved when the tasks are unstructured (House, 1996). In the case of volunteering, the empowering effect of participative leader behaviours can be illustrated by the study of Gilbert et al. (2020), in which a community garden leader gave young volunteers the responsibility to take the produce to other elderlies, thereby allowing the young volunteers to perceive themselves as helpers and providers. As a result, it can bring a positive effect on volunteers’ self-esteem and sense of purpose.

Leaders may also fulfil the enhancement motivation of volunteers by simply recognising their contribution or a job well done. Recognition allows one to feel appreciated, honoured and, therefore, esteemed (Bailey, 2003). The fact that leaders are willing to spend time to give personalised recognition may also add value to the receivers (Luthans, 2000). In Esmond’s (2009) study on emergency services volunteers, she suggested that recognition often serves as a powerful underlying force that keeps volunteers going when they feel like quitting.

Discussion

By examining the six main volunteer motivations, we have distilled precise leader behaviours from extant literature that might be effective in triggering the corresponding motivation. This integration of the functional approach to volunteer motivation and leadership theories can be useful for managers of volunteers to better understand why volunteers start and keep volunteering, and also, help them to discern which leader behaviour are most likely to result in more sustainable volunteer workforces. This is especially important for organisations that rely on long-term volunteers to deliver essential services. We suggest, as presented in Table 1, that there are certain behaviours derived from the decades of leadership research that can be adopted to help volunteers to express personal values, learn, advance careers, obtain social rewards, enhance self-esteem and deal with negative feelings.

People can be attracted to volunteer and become more committed to volunteer service when there is a match between the benefits provided by volunteering and their needs and motives (Stukas et al., 2009). Without the monetary incentives and the fact that volunteers can come and go at will, attention should be on how organisations can fulfil the existing needs underlying the motivation to work for no pay. Our interest has been in the role of leadership in this process. Attacking this question from a starting point of one existing leadership theory is futile. For one, participants in an unpaid workforce are varied in the expectations they have for volunteering (Neely et al., 2021) and therefore require different leadership models to satisfy them. Through our narrative review on how specific leader behaviours can effectively address various volunteer motivations, we respond to the calls for more leadership scholars’ attention to volunteering (Vieira Da Cunha & Antunes, 2022) and the calls for more volunteer scholars’ attention to leadership (Posner, 2015). Given the increasing reliance on volunteers against the backdrop of declining volunteer numbers, this article can benefit volunteer practitioners, providing them with a succinct way to navigate the plethora of leadership theories to identify discrete leader behaviours that might be effective for motivating volunteers.

Limitations and Recommendations for Future Research

As the motivation for this article stems from the limited work that comprehensively examined the linkage between volunteering and leadership, providing emerging, novel insights from recent leadership research was not our intention. Although this is a significant limitation, we believe that the connections we have proposed between each functional motivation and leadership theory can enrich the conversation surrounding volunteer leadership. Future work is required to examine if the listed behaviours are indeed preferred by volunteers with the corresponding motivation or if they can successfully fulfil or trigger the related motivation. Moreover, as we positioned this article as a conceptual exploration of the topic, the propositions we made should not be regarded as definitive conclusions. Rather, we hope that they guide future conceptual and empirical investigations into the relationships between leader behaviour and volunteers’ motivations to continue volunteering.

We also recognise that our chosen approach to volunteer motivation and our interpretations of each motivation affect the choices we made on which leadership literature to draw from. Likewise, contextual factors such as followers’ characteristics, organisational capabilities and culture, and contingencies should also be considered in examining the links between leader behaviours and outcomes (Behrendt et al., 2017). The interplay between leadership, motivation and contextual factors is deeply complex. We urge future research to consider the multifaceted nature of volunteer leadership, the diversities of volunteering contexts, and the pressing issue of volunteer retention.

Under-researched Areas and Recommendations for Volunteer Recruitment

The six VFI motivations also represent the psychological functions that anyone may seek to fulfil regardless of the context (Lavelle, 2010). This has led to our discovery of areas where leadership research has paid less attention to. For example, how leaders could adequately enhance the protective mechanism of work activities for those who wish to escape from their personal negative feelings; how leaders may increase the opportunities for employees to receive social rewards. Additionally, we suggest that in order to tackle the problem of declining volunteering, it is equally important for leaders to effectively recruit volunteers. Though leadership has been associated with charisma that attracts people to follow (Corcoran & Wellman, 2016), there was less attention on how leaders may attract new followers from outside the organisation (Banks et al., 2017). Future research may consider how leaders can attract outsiders to become volunteers. Some recommendations derived from the volunteering literature that are relevant to each of the six motivations are illustrated as follows.

Based on our discussion on the values motivation, a leader can communicate organisational goals clearly in a way that helps volunteers internalise the goals and become advocators of the organisation themselves, which may help to attract others to join the organisation (Linda & Welty Peachey, 2012). For the understanding and career motivations, a leader should explicitly promote the informal learning benefits and the benefit of applying soft skills gained from volunteering to formal workplaces (Schugurensky & Mündel, 2005). Based on the concept of social influence, a leader can adopt a word-of-mouth recruitment strategy (Freeman, 1997; Neumann, 2010) as well as target specific demographic groups or promote the organisational culture, since people tend to be attracted to others who share similar social identities (Machin, 2007) or similar values (Hudon, 2008; Wilson, 2001). Drawing from the concept of protective motivation, a leader can consider message framing when recruiting. For example, they can emphasise to potential volunteers the negative consequences if no one is willing to help, while also highlighting their ability to help those in need (Lindenmeier, 2008). How leaders can attract new volunteers while setting the right expectations to sustain their participation is an interesting phenomenon that can be further explored (Dunlop et al., 2022), where instead of the hiree being assessed by the organisation, the organisation is assessed by them.

Conclusion

Volunteering is of huge economic and practical value to society. The decline in people’s propensities to volunteer through organisations could weaken our ability to handle the impact of increasing natural disasters and societal demands. Our goal in this article is to identify links between volunteer motivations and leadership theories by using a well-established volunteer motivation model to pinpoint discrete leader behaviours that might trigger various motivations to volunteer. Our aim is to contribute to scholars and practitioners in understanding how leadership may be applied to volunteering. It appears plausible that there are connections between discrete leader behaviours, rather than holistic leadership styles, that are capable of triggering and fulfilling volunteer motivations. Future research can be designed to map this connectivity and to identify those behaviours with precision where they exist. Such knowledge can assist organisations and leaders to use or hone their behaviours as the trigger to attract more volunteers and keep them volunteering longer. We anticipate that the cumulative knowledge of leadership scholarship is well-positioned to contribute to building a sustainable pipeline of volunteers. Going forward, because we expect increasing calls for volunteers to support essential services where the government is short of supply, we hope this work will introduce new perspectives and inspire an array of much needed volunteer leadership research.
