How are union contracts negotiated through collective bargaining?

"A labor agreement, or union contract, is created through collective bargaining. Typically, both management and union negotiation teams are made up of a few people. One person on each side is the chief spokesperson. Bargaining begins with union and management negotiators setting a list of contract issues that will be discussed. Much of the bargaining over specific details takes place through face-to-face meetings and the exchange of written proposals. Demands, proposals, and counterproposals are exchanged during several rounds of bargaining. The resulting contract must be approved by top management and ratified by the union members. Once both sides approve, the contract is a legally binding agreement that typically covers such issues as union security, management rights, wages, benefits, and job security.\n\nA union wants all employees to be union members. This can be accomplished by negotiating a union security clause. The most common union security arrangement is the union shop, whereby nonunion workers can be hired by the firm, but then they must join the union, normally within 30 to 60 days. An agency shop does not require employees to join the union, but to remain employees, workers must pay the union a fee (known as the agency fee) to cover the union’s expenses in representing them. The union must fairly represent all workers, including those in the bargaining unit who do not become members. Under the Taft-Hartley Act of 1947, a state can make any and all forms of union security illegal by enacting a right-to-work law. In the 28 states that have these laws, employees can work at a unionized company without having to join the union. This arrangement is commonly known as an open shop. Workers don’t have to join the union or pay dues or fees to the union."
