State & Federal Law Hybrids are the Norm.  

The application of state labor and insurance laws, as well as federal labor and employee benefit laws, to employer-sponsored benefit plans has been the norm in Texas and other states for many decades.  For example, just like Texas injury benefit programs, workers’ compensation programs must comply with federal laws like the Family and Medical Leave Act (FMLA), Americans With Disabilities Act (ADA), Occupational Safety and Health Act (OSHA), and Fair Labor Standards Act (FLSA).
