As a member of a union, you receive all the benefits achieved by the union in negotiating employment benefits with your employer. When your union negotiates payment and benefits on behalf of many employees, you are part of a much larger group that generally has much greater bargaining power in dealing with employers. For example, one worker may believe new safety measures should be implemented but may not be able to get his employer to agree. If more workers band together in a bargaining unit to pressure the company to implement the safety measures, there is a much better chance the company will listen. This is commonly referred to as collective bargaining.
Collective bargaining results in many positive benefits. The wages of union members are, on average, 30% higher than those of workers who do not have union representation; 93% of union workers are entitled to health benefits, while only 69% of non-union workers do; and 77% of union workers have a guaranteed, pension, compared to only 17% of non-union workers. In addition, unions often lobby for legislation and political candidates that are more favorable to employees.
