Recently, the union concluded negotiations for some 75,000 commercial cleaners on the East Coast. The New York agreement alone involves 22,000 commercial cleaners.32 The union negotiates with a multi-employer association or with employer groups, and its agreements bind signatory employers in all cities where the union has local agreements. In other words, in the New York agreement, for example, New York employers agree to abide by the Philadelphia collective agreement when they work in Philadelphia. In recent negotiations, SEIU Local 32BJ has gained substantial wage increases, pension improvements, new protection against sexual harassment and much more. Employers also agreed to a union recognition procedure for cleaners in Miami, opening the door to extending the protection of collective agreements to 1,500 additional building cleaners in miami. The Court also clarified that freedom of association means that an individual has the right to develop his own beliefs rather than let him be thwarted by the state. For example, unions are prohibited from using non-member money to revive an ideological cause that has nothing to do with the union`s duties as an agent. The National Labor Relations Act prohibits employers from interfering in the exercise of rights relating to the organization, creation, membership or support of a labour organization for collective bargaining, from restricting or compelling or prohibiting workers. Similarly, labour organizations must not restrict or coerc workers into the exercise of these rights. A collective agreement is a written contract between an employer and a union representing workers. The KBA is the result of a broad negotiation process between the parties on issues such as wages, hours and terms of employment. What are the rules governing collective bargaining for a contract? The NLRB has long believed that a unit with a single agency is probably appropriate.15 This rule is the language of the NNRA that describes potential bargaining units as „employer unit, craft unit, factory unit or subdivision of it.“ 16 As a general rule, the only institution is a single job, although workers and trade unions can seek unity with several establishments, or even a national unity, and try to convince the NLRB of the appropriateness of such a unit. The analysis examines whether work, personnel, supervision and labour relations in the various institutions are sufficiently linked to warrant unity with multiple annexes.17 The provisions of the NLRB bargaining units are rarely reversed.
