Job sharing or work sharing and short time or short-time working refer to situations or systems in which employees agree to or are forced to accept a reduction in working time and pay. These can be based on individual agreements or on government programs in many countries that try to prevent unemployment. In these, employers have the option of reducing work hours to part-time for many employees instead of laying off some of them and retaining only full-time workers. For example, employees in 27 states of the United States can then receive unemployment payments for the hours they are no longer working.
