If you become disabled during your military service, your employer must make efforts to accommodate you. For less than 31 days of service, you must return to work on the first day of the next work period. For periods of service between 31 days and 180 days, you must submit an application for reemployment within 14 days after finishing your service. If you served for more than 180 days, you have 90 days to submit an application for reemployment. If you are hospitalized or recuperating from service-related illness or injury, the application deadlines are extended for up to two years.
Most states also have laws requiring employers to give employees time off for military duties.
