There are extensive labor employment laws in the United States. These laws may be referred to as the body of laws known as "employment law." While there are many state laws pertaining to the rights of employees in the workplace, there are extensive federal laws which seek to protect employees. The federal laws have more widespread applicability, while every state has its own unique statutes which provide for employee protections. These employee labor laws include laws which relate to a significant array of topics. Such 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 aim of all of these laws is to provide for employee to have certain guaranteed protections while in the workplace and to avoid the abuse of workers by employers. It is important to note that not all federal employee labor laws apply to all employers; every law contains criteria in order to identify those employers which must comply with the particular employee labor law.
