Arranging work time in new and flexible ways has been a topic of growing interest for the past ten years. This handbook for employers explains one way in which jobs can be made more flexible--job sharing. It discusses ways that work hours can be shared with potential benefits for employer and employees. Topics discussed include definition of job sharing, kinds of jobs that can be shared, benefits to the organization, employer concerns, union attitudes, how job sharing works, potential problems, ways to make job sharing successful, and reactions from supervisors of job sharers. A chart of possible job sharing arrangements is also included. (KC)
