Step-by-step explanation:
Labor unions are groups that represent employees, generally on a local or organizational level, for the primary purpose of receiving information from employers and conveying it to employees about the workforce and the health of the enterprise.
Unions negotiate on behalf of their members to settle disputes involving wages, working conditions, and benefits. They also work to influence legislation and strengthen their bargaining position with employers. Some examples of labor unions are the American Federation of Labor-Congress of Industrial Organization (AFL-CIO), the American Federation of Teachers, and the United Auto Workers.
