Answer:
Wagner Act
Step-by-step explanation:
Civil rights was about discrimination, Fair Labor Standards is about minimum age and other regulations. Occupational Health and Safety (OSHA) is about safety of the workplace. The Equal Pay Act is waged based on gender. So, we have the Wagner Act left.
The National Labor Relations Act of 1935 (also known as the Wagner Act) is a foundational statute of United States labor law. The act grants the right of employees, as long as they're in the private sector, to organize in Unions.
