Which act aims to protect the rights of employees regarding their health and safety at work?

The Occupational Safety and Health Act is specifically designed to ensure that employees work in environments that are free from recognized health and safety hazards. This legislation established the Occupational Safety and Health Administration (OSHA), which sets and enforces standards for workplace safety and health. The act requires employers to provide their employees with workplaces that are safe and without serious hazards, thereby directly protecting their health and safety at work.

The other acts mentioned, while important for various worker rights, do not focus directly on workplace health and safety. The Americans with Disabilities Act aims to prevent discrimination against individuals with disabilities in various areas, including employment, but it does not specifically address general workplace hazards. The Employee Polygraph Protection Act regulates the use of lie detector tests but does not pertain to health and safety. The Fair Labor Standards Act primarily deals with wage laws, including minimum wage and overtime pay, rather than issues concerning health and safety in the workplace. Thus, the Occupational Safety and Health Act is the correct choice for the question regarding employee health and safety rights.
