Based on the Job Demands Resources Model (JD-R), this study investigates the mediating role of meaningful work and work engagement in the association between job resources and employees' intention to stay. A cross-sectional study was conducted through an online survey of 217 employees from different organizations in Puerto Rico. We examined a serial mediation analysis through structural equation modeling. The results indicate that job resources are positively related to meaningful work, while meaningful work is positively associated with work engagement. Further, job resources are indirectly associated with the intention to stay through meaningful work and work engagement. This study contributes to understanding the role of meaningful work and engagement in the JD-R model's motivational-driven process and how these mechanisms promote positive work outcomes in terms of the retention of human capital. Designing jobs and strategies at the workplace to develop meaning and engagement seems crucial to retain employees.

本研究基于工作需求资源模型（JD-R），探讨了有意义的工作和工作投入在工作资源与员工留下意愿之间的中介作用。通过对波多黎各不同组织的 217 名员工进行在线调查，进行了一项横断面研究。我们通过结构方程模型检查了串行中介分析。结果表明，工作资源与有意义的工作正相关，而有意义的工作与工作投入正相关。此外，工作资源与继续从事有意义的工作和工作投入的意愿间接相关。这项研究有助于理解有意义的工作和参与在 JD-R 模型的动机驱动过程中的作用，以及这些机制如何在保留人力资本方面促进积极的工作成果。在工作场所设计工作和策略以培养意义和参与度似乎对于留住员工至关重要。
