From serious diseases to common colds, employers must manage a range of illnesses and disabilities that affect their employees. Employers must consider liability issues, federal and state regulations, methods to stem the spread of communicable diseases, and employee concerns and fears. There are several laws that prohibit employment discrimination based on disability or serious health conditions, including the Americans with Disabilities Act (ADA), the Federal Rehabilitation Act of 1973, the Family and Medical Leave Act of 1993 (FMLA), and the Occupational Safety and Health Act (OSH Act).
