Job sharing, a new option in permanent part-time employment, is attracting national attention as a viable alternative to more traditional patterns of work. Job sharing is defined as an arrangement whereby two employees hold a position together, whether they are as a team jointly responsible for the whole or separately for each half, dividing time, salary, and fringe benefits. A survey of 238 job sharers was conducted to determine the characteristics of the people choosing this alternative work pattern and their experiences and responses to the job sharing situation. Job categories represented include teachers (26 percent), administrators (25 percent), clerical (15 percent), counseling and social service (13 percent), and researchers (9 percent). The remaining category consists of such diverse occupations as editors, librarians, bank tellers, physicians, and food service workers. The study includes a review of the definitions and experiments through which the job sharing concept has evolved, an analysis of the survey data, and selected indepth interviews with partners, supervisors, and some of their full-time coworkers, and concludes with some policy implications for more extensive use of this alternative work pattern.
