An extensive commitment to nonwork roles was negatively associated with the job performance of 182 women legal secretaries. In addition to its direct negative effect on job performance, nonwork role commitment had both a negative indirect effect (through emotional energy expended on nonwork roles) and a positive indirect effect (through resources acquired from nonwork roles) on job performance. Consistent with a family-to-work conflict perspective, the negative effect was stronger than the positive effect. We suggest that the level and type of job occupied by the respondents in the study may have been responsible for the dominance of the negative effect and encourage researchers to examine the contextual influences that might explain the conditions under which commitment to life outside of work dampens or promotes performance in the work domain.
