Role of collective bargaining unit

A bargaining unit, in labor relations, is a group of employees with a clear and identifiable community of interests who are represented by a single labor union in collective bargaining and other dealings with management. Examples would be non-management professors, law enforcement professionals, blue-collar workers, clerical and administrative employees, etc. Geographic location as well as the number of facilities included in bargaining units can be at issue during representation cases. https://en.wikipedia.org/wiki/Bargaining_unit.

A collective bargaining unit refers to a group of employees sharing mutual interests within a given employer unit, comprised of all or less than all of the entire body of employees in the employer unit or any specific occupational or geographical grouping within such employer unit. (Book V of the Labor Code of the Philippines)

A bargaining unit is more accurately called a "collective bargaining unit" (CBU). Such unit is represented by a democratically-elected representative formerly called the exclusive bargaining representative (EBR) now called the sole and exclusive bargaining agent (SEBA).

The labor organization designated or selected by the majority of the employees in an appropriate collective bargaining unit shall be the exclusive representative of the employees of such unit for the purpose of collective bargaining.
