A labor union, also known as trade union, is an organization that represents workers in negotiations with employers over wages, benefits and working conditions. The goal of a labor union is to improve the rights and well-being of its members by providing them with better pay, job security, health care, pensions and other benefits.
Labor unions also advocate for their members on issues such as safety in the workplace, fair wages, and working conditions. They negotiate collective bargaining agreements that set forth the terms of employment for unionized workers. In addition to representing employees during contract negotiations, labor unions may provide other services such as legal representation or assistance with job-related issues.
In summary, a labor union is an organization that represents and advocates on behalf of its members in their dealings with management.
