Poor working conditions and high employee turnover in eldercare have frequently been addressed over the years. The aim of the study is to examine the relation between work overcommitment and employee well-being and turnover intentions in eldercare and whether leader support and role clarity moderate the relation between overcommitment and employee outcomes. A questionnaire was distributed to workplaces in eight Swedish municipalities. The results show that overcommitment was related to employees’ impaired well-being, as well as to their turnover intentions. We also found that leader support buffered the negative effects of overcommitment. The role clarity was quite high; however, it did not have a moderating effect.
