Union contracts, like any other employment contract, usually contain details about how to terminate an employee, how pay is structured, when raises are given, and other financial information. The difference here is that a third party, the union, negotiates this legal document for the workers it represents. Many times what the workers want or feel is important is not in these voluminous documents, which are only read by a few union representatives.
A union member should always read his or her union contract to make sure that he or she is getting all the rights and protections in the workplace that are listed in the contract. Union members should lobby their representatives for the benefits that are important to them before contract negotiations between the employer and union even begin.
