Purpose: The purpose of this paper is to study the demand-control-support (DCS) model on burnout in male and female managers and non-managers, taking into account genetic and shared family environmental factors, contributing to the understanding of mechanisms of how and when work stress is related to burnout.

Design/methodology/approach: A total of 5,510 individuals in complete same-sex twin pairs from the Swedish Twin Registry were included in the analyses. Co-twin control analyses were performed using linear mixed modeling, comparing between-pairs and within-pair effects, stratified by zygosity and sex.

Findings: Managers scored higher on demands and control in their work than non-managers, and female managers seem to be particularly at risk for burnout facing more demands which are not reduced by a higher control as in their male counterparts. Co-twin analyses showed that associations between control and burnout as well as between demands and burnout seem to be affected by shared family environmental factors in male non-managers but not in male managers in which instead the associations between social support and burnout seem to be influenced by shared family environment.

Practical implications: Taken together, the study offers knowledge that shared environment as well as sex and managerial status are important factors to consider in how DCS is associated to exhaustion.

Originality/value: Using twin data with possibilities to control for genetics, shared environment, sex and age, this study offers unique insight into the DCS research, which focusses primarily on the workplace environment rather than individual factors.
