Final answer:
The statement that modern U.S. labor relations law relies on a combination of federal and state laws, judicial decisions, and administrative agency decisions is true. Key legislation includes the National Labor Relations Act and Taft-Hartley Act, supplemented by other laws ensuring worker's rights and protections. Therefore, the correct option is A.
Step-by-step explanation:
The statement is true. Modern U.S. labor relations law is indeed based on a combination of federal and state statutory laws, local government ordinances, judicial decisions, and regulations enforced by administrative agencies such as the National Labor Relations Board (NLRB). The National Labor Relations Act of 1935 and the Taft-Hartley Act of 1947 are key pieces of legislation that shaped labor rights and union activities in the United States. Additionally, various other laws contribute to the regulation of labor markets including those concerning minimum wages, maximum work hours, child labor, workplace health and safety conditions, discrimination, and family leave.
Organized Labor and the labor union movement have evolved over time in response to changes in working conditions, particularly during the Industrial Revolution. The evolution of the labor law framework, including the right to form unions and engage in collective bargaining and striking, has been integral to balancing the power dynamics between employers and workers. For public sector employees, the right to strike can vary depending on state laws due to the potential impact on society's functioning.
