Flexible work schedules offer the promise of a low-cost option for helping people manage work and family responsibilities. Alternative work schedules include part-time work, job sharing, work sharing, shiftwork, compressed work week, flexitime, and flexiplace. Flexitime is the most prevalent full-time flexible schedule and is second in prevalence only to part-time work among all flexible work schedules. Its prevalence in the workplace continues to increase steadily. Research studies on the effects of flexitime schedules have not proven very definitive because of design problems. They do suggest that in many work situations both the organization and the individual worker can gain from this arrangement. Unresolved issues involving flexitime include occupational constraints, the reluctance of supervisors, legal constraints, and union resistance. (The paper concludes with recommendations for researchers, public and private employers, labor unions, and government. A 21-item reference list is included.) (CML)
