Using data from a 2005 survey of U.S. workers, we find that a high percentage of employed men and women report that work interferes with nonwork life. This research offers three main contributions: (1) we document the social distribution of work-nonwork interference across social statuses and dimensions of stratification; (2) we develop a conceptual framework that specifies the influence of a comprehensive set of work resources and demands on interference and their contributions to its social distribution; and (3) we advance a "stress of higher status" perspective to understand the paradoxical influence of some work conditions on work-nonwork interference. Findings generally support both the demands hypothesis and the stress of higher status hypothesis, with patterns from both factors contributing substantially to the social distribution of work-nonwork interference. This article refines and elaborates the job demands-resources model with insights from border theory. (Contains 3 footnotes, 4 tables, and 4 figures.)
