This handbook provides detailed information about job sharing for both administrators and potential sharers who are interested in implementing this new work arrangement. It incorporates results of a survey of job sharing in health care organizations as well as interviews and contacts with health care providers. A section on employees and job sharing begins by considering benefits to sharers. These three basic steps involved in the process for the would-be sharers are discussed: finding a partner, developing a proposal, and making a presentation to the employer. Sample proposals and case studies are provided. A section on employers and job sharing first addresses questions of cost and management, including salary, fringe benefits, new benefits for employees, minimization of layoffs, and service improvement. Discussion of the implementation process focuses on reviewing a written proposal, interviewing teams, and enlarging the scope. A policy/procedure guidance format is provided. Three case studies follow. Attachments include a synopsis of survey results, addresses for the National Network for Work Time Options, and a list of references. (YLB)
