I think there is a bargaining relationship between an employer and a union, especially workers who « assign » their bargaining rights to the union. Workers don`t really get a contract with their employer, the union does. Good faith negotiations are aimed at obtaining collective agreements that are acceptable to both parties. In the absence of an agreement, dispute resolution procedures can be used, from mediation to arbitration to mediation.  Collective bargaining (section 8 (d) &8 (b) (3)).

Finally, workers who do not have the right to bargain collectively also convey their « bargaining demands » to the public. Domestic workers in Hawaii, Massachusetts, California, Connecticut and New York have successfully passed the Domestic Workers` Bill of Rights that guarantee them access to overtime pay and adequate protection in the workplace.
The vast majority of Americans do not have access to a collective bargaining process. Employers` hostility to trade unions is chilling organizing efforts.  Workers who want to unite to raise wages and standards are looking for new « ramps » to negotiate, especially if their employers refuse to recognize their union or bargain collectively with them. Sometimes the NRA`s bargaining structure does not allow people to negotiate with their « real » boss – the company that has real economic control over their work, but is not their direct employer. In these cases, employees use alternative strategies to build power and influence their salaries and norms. The 1998 ILO Declaration on Fundamental Principles and Rights at Work reaffirms the importance of effective recognition of the right to collective bargaining. Not all workers are considered « workers » under the NRA. Superiors and managers, although paid employees, are considered managers and fall on the side of employers in negotiations.
Workers also do not need to be part of a union to conduct collective bargaining. A group of workers may elect a representative who negotiates on its behalf, but who is nevertheless covered by the NLRA. .
