In the face of declining enrollments and widespread reductions-in-force in school systems, job sharing can provide part-time positions for persons unable to work full-time and can allow some individuals to maintain their positions on a part-time basis as an alternative to being laid off. Job sharing can also benefit school systems by increasing the size of the potential applicant pool. Job sharing, however, is not a panacea for school staffing problems and administrators should weigh its benefits and drawbacks before determining its viability as an employment option. This publication examines various aspects of job sharing, including an overview of the general literature. It delineates the advantages and disadvantages of job sharing to employers and employees and gives specific consideration to job sharing in teaching. Also included are sample contract language, policies and guidelines from several school districts across the nation, and legislation designed to enlarge opportunities for permanent, part-time work in California, Minnesota, and Hawaii.
