Employers are prohibited from discriminating against employees based on what?

Employers are prohibited from discriminating against employees based on union activities because such discrimination undermines workers' rights to organize and participate in collective bargaining. This protection is rooted in laws such as the National Labor Relations Act (NLRA), which gives employees the right to form, join, or assist labor organizations, and prohibits employers from retaliating against individuals for participating in these activities.

Union activities enable employees to advocate for better working conditions, fair wages, and other important job-related benefits. By protecting these activities, the law fosters an environment where employees can freely engage in collective efforts without fear of reprisal from their employers. This is crucial for maintaining balance and fairness in the workplace, allowing for legitimate dialogue between employees and management on employment terms and conditions.
