Abstract Objectives We aimed to explore the association between long working hours and health‐related productivity loss (HRPL), due to either sickness, absenteeism or presenteeism, stratified by household income level. Methods From January 2020 to February 2020, data were collected using a web‐based questionnaire. A total of 4197 participants were randomly selected using the convenience sampling method. The nonparametric association between weekly working hours and HRPL was determined. Subsequently, a stratified analysis was conducted according to household income (1st, 2nd, and 3rd tertiles). Finally, the differences in HRPL of the different working hour groups (<40, 40, 40‐51, and ≥52 hours) were investigated using a multivariate linear regression model. Results Long working hours were more significantly associated with HRPL, as compared to the ‘standard’ working hours (40 hours/week). A larger proportion of productivity loss was associated with the presenteeism of workers, rather than absenteeism. The relationship between HRPL and weekly working hours was more prominent in the lower household income group. Conclusions The results of our study indicate that HRPL is associated with long working hours, especially in the lower household income group. Reducing the workload for the individual employee to a manageable level and restructuring sick leave policies to effectively counteract absenteeism and presenteeism may be a feasible option for better labor productivity and employee health.

长时间工作与健康相关生产力损失的关联，以及收入水平对其的不同影响：对韩国工人的横断面研究

摘要 目标我们旨在探索长时间工作与健康相关生产力损失 (HRPL) 之间的关联，原因是疾病、缺勤或出勤，按家庭收入水平分层。方法 2020 年 1 月至 2020 年 2 月，使用网络问卷收集数据。使用便利抽样方法随机抽取了 4197 名参与者。确定了每周工作时间和 HRPL 之间的非参数关联。随后，根据家庭收入（第一、第二和第三个三分位数）进行分层分析。最后，使用多元线性回归模型研究了不同工作时间组（<40、40、40-51和≥52小时）的HRPL差异。结果 长时间工作与 HRPL 更显着相关，与“标准”工作时间（40 小时/周）相比。更大比例的生产力损失与工人的出勤率有关，而不是旷工。HRPL 与每周工作时间之间的关系在较低家庭收入组中更为突出。结论 我们的研究结果表明 HRPL 与长时间工作有关，尤其是在低收入群体中。将个别员工的工作量减少到可管理的水平并调整病假政策以有效抵消缺勤和出勤可能是提高劳动生产率和员工健康的可行选择。HRPL 与每周工作时间之间的关系在较低家庭收入组中更为突出。结论 我们的研究结果表明 HRPL 与长时间工作有关，尤其是在低收入群体中。将个别员工的工作量减少到可管理的水平并调整病假政策以有效抵消缺勤和出勤可能是提高劳动生产率和员工健康的可行选择。HRPL 与每周工作时间之间的关系在较低家庭收入组中更为突出。结论 我们的研究结果表明 HRPL 与长时间工作有关，尤其是在低收入群体中。将个别员工的工作量减少到可管理的水平并调整病假政策以有效抵消缺勤和出勤可能是提高劳动生产率和员工健康的可行选择。
