The Family and Medical Leave Act of 1993 generally applies to employers of 50 or more employees in 20 weeks of the last year. Employees must have worked over 12 months and 1250 hours in the last year (around 25 hours a week). However, employees are not eligible if they work at a work site where the total number of employees employed by the employer within 75 miles of that work site is less than 50. A worksite includes a public agency, including schools and state, local, and federal employers. The 50 employee threshold does not apply to public agency employees and local educational agencies. There are special hours rules for certain airline employees.
