Employers must comply with labor laws. While there are state laws which pertain to the rights of employees in the workplace, there are extensive federal laws which seek to protect employees. Labor law topics include compensation, discrimination, benefits, union activities, medical and family leave job protection, job safety, workers' compensation, garnishment of wages, use of employee polygraph tests and more. Some of the most widely referenced federal employee labor laws include the Family and Medical Leave Act, the Fair Labor Standards Act, the Occupational Safety and Health Act and the Employee Retirement Income Security Act. The state laws are very similar to the federal laws. However, state laws usually offer a greater level of employee protection. Overall, the focus of all of these laws is to provide for employee to have certain guaranteed protections while in the workplace, while seeking to avoid the abuse of workers by employers.
