NLRA

The National Labor Relations Act of 1935, a foundational statute in United States labor law which grants workers the right to form unions and engage in collective bargaining.

Culture of Conflict

The environment or atmosphere where opposing interests, viewpoints, or priorities frequently result in disputes or confrontations.
