What is the primary function of labor unions?

The primary function of labor unions is to represent workers against unfair labor practices. Unions are organizations formed by workers in various industries to advocate for their rights, improve working conditions, negotiate wages, and provide a collective voice in discussions with employers. By uniting workers, unions can leverage their collective bargaining power to negotiate better terms than individual workers might achieve on their own. This representation is essential in addressing issues such as unfair dismissals, workplace safety, and equitable pay, ensuring that workers' rights are protected and upheld against potential exploitation.

In contrast, the other options do not align with the core purpose of labor unions. Promoting individual entrepreneurship is typically associated with fostering business innovation and independence rather than representing worker interests. Managing government regulations falls under the jurisdiction of government entities and is not a direct function of labor unions. Finally, the notion of eliminating competition in the workforce contradicts the essence of unions, which aim to improve worker conditions rather than undermine job opportunities.
