Even though labor unions are considered non-profits by the Internal Revenue Services, they operate like most big businesses playing with thousands, if not millions, of dollars; money in, money out.
In the U.S., labor unions have operated for centuries. As a business, unions operate by selling membership services, representing employees exclusively to their employer. Unions expect compensation for their services and charge employees membership dues, initiation fees, special assessments and even the potential for fines.
Congress enacted the National Labor Relations Act ("NLRA") in 1935 to protect the rights of employees and employers, to encourage collective bargaining, and to curtail certain private sector labor and management practices, which can harm the general welfare of workers, businesses and the U.S. economy. At the time when the NLRA was enacted 16.6% of all Americans were already unionized.
Unionization skyrocketed within the first decade when unionization doubles to over 35%. Since its peak, unionization has drifted into irrelevance. Unions today only represent 1 of every 16 private sector worker (6.2% - BLS 2019). 93% of private sector workers today choose to remain union-free, representing themselves directly with their employer in an open, respectful 2-way relationship without the interference of an unwarranted third party.
