This study reveals the mediating effect of musculoskeletal complaints (MSCs) and the moderating effect of job resources on the relationship between job demands and presenteeism of workers in dependent self-employment (DSE). Recently, as the number of workers in DSE has increased, the importance of adjusting job demands to control presenteeism, address MSCs, and develop job resources has increased. Objectives We tested the effects of job demands on presenteeism to investigate the mediation of musculoskeletal complaints (MSCs) and the moderating effects of job resources among dependent self-employment (DSE) workers in Korea. Methods Using data from the fifth Korean Working Conditions Survey, we analyzed 2252 workers, and a two-step regression analysis was used to test the mediated effect of MSCs and moderated the effect of job resources on the relationship between job demand and presenteeism. Results Musculoskeletal complaints mediate the relationship between job demands and presenteeism. Job control moderated the relationship between MSCs and presenteeism among the job resources. However, the conditional indirect effect of job demands on presenteeism through MSCs was independent of job resource levels among DSE workers. Conclusions Various strategies are needed to address MSCs and enhance job resources for DSE workers, which might diminish the negative effect of job demands on presenteeism.
