Community of Interest Law and Legal Definition

Community of interest generally refers to a common interest of class of people living in a community. It also refers to a common grievance that must be shared by all class members to maintain the class action. Under labor law, community of interest is an important criterion used by the National Labor Relations Board (NLRB) to determine whether a group of employees should be allowed to act as a bargaining unit.

In NLRB v. Catherine McAuley Health Ctr., 885 F.2d 341 (6th Cir. 1989), it was held that a bargaining unit is determined when the unit shares a community of interests in wages, hours, and other conditions of employment. However, the following factors also indicate a community of interests:

1.Similarity in skills, interests, duties, and working conditions;

2.Functional integration of the plant, including interchange and contact among the employees;

3.The employer's organizational and supervisory structure;

4.The bargaining history; and

5.The extent of union organization among the employees.
