Which sectors are covered by the National Labor Relations Act?

The National Labor Relations Act (NLRA), enacted in 1935, primarily covers the private sector, and its main goal is to protect the rights of employees and employers in their relationships with each other. This includes the rights to organize, engage in collective bargaining, and take part in concerted activities for mutual aid or protection.

The correct choice reflects that the NLRA applies to private sectors, which includes a wide range of industries, such as manufacturing, retail, and skilled trades. Skilled trades, such as plumbing, electrical work, and carpentry, often involve unions and collective bargaining, making them directly relevant to the provisions of the NLRA.

Other sectors mentioned in the options, such as education, healthcare, and the federal government, typically fall under different regulations, such as public labor laws that may not provide the same protections or rights as those granted by the NLRA. Non-profit organizations also do not generally fall under the NLRA unless they operate in a for-profit capacity, making the private sector focus of the correct answer particularly significant.
