Job-sharingis an innovative employment alternative that originated in Sweden and is becom-ing popular in the United States (for example, in 2001, 26% of companies in the U. S. offeredit as a flexible work option). Firms that offer job-sharing plans allow two or more persons towork part-time, sharing one full-time job. For example, two job-sharers might alternate workweeks, with one working while the other is off. Job-sharers never work at the same time, andmay not even know each other. Job-sharing is particularly attractive to working mothers andto people who frequently lose their jobs due to fluctuations in the economy. In a recent surveyof 1,035 major U. S. firms, approximately 23% offer job-sharing to their employees. Required:
