Social relations at work as a moderator of the effects 
of job demands on mental and physical health among teachers

Łukasz Baka 



Abstract
The study was intended to verify the theoretical assumptions of the Job Demands – Resources model (JD-R). The authors of the JD-R model argue that job demands lead to deteriorated mental and physical health both directly and indirectly – through increased job burnout. Moreover, job resources buffer negative effects of job demands on health. However, it is not clear what exactly is buffered by job resources – do they only buffer direct effects of job demands on health or do they also buffer effects of job demands on job burnout and effects of job burnout on health? The study sought to investigate (1) the role of the job burnout as a mediator between job demands, depression and somatic complaints; (2) the role of social relations as a moderator of the relationship between job demands and job burnout and between job burnout and depression and somatic complaints. Social relations included supervisors’ support, coworkers’ support and psychological climate at work. Participants were 316 teachers. As predicted by JD-R model, high job demands led to depression and somatic complaints both directly and indirectly – through increased job burnout. Support received from supervisors buffered effects of job demands on job burnout and effects of job burnout on depression but not on somatic complaints. The predicted moderating function of coworkers’ support and of the psychological climate at work was not supported by the data.

Key words: Job Demands – Resources Model, Job burnout, social relations, health
