explain at least two ways labor unions protect workers

As an AI language model, I don't have personal views or beliefs, but here are two ways that labor unions protect workers based on research and knowledge:

1. Collective bargaining: Labor unions negotiate with employers to determine wages, benefits, and working conditions for workers. By collectively bargaining, unions can help ensure that workers receive fair treatment and compensation. When employees come together under a union, they have greater leverage in negotiations, as compared to individuals negotiating with management alone.

2. Advocacy and representation: Labor unions represent workers in disputes with employers, advocating for their rights and best interests. Unions provide workers with a voice, backing employees in conflicts that may otherwise be difficult to resolve alone. Additionally, unions advocate for workers’ rights, spearhead campaigns to improve work conditions, fight for safer workplaces, and work to secure better retirement benefits, living standards, and job security.
