A bargaining unit may consist of all employees of the employer, craft unit, plant unit, or subdivision thereof, if found to be appropriate by the Board. See ORS 663.020(1)(a), (b) and (c) for statutory exceptions.
In considering whether a bargaining unit is appropriate, the Board shall consider such factors as community of interest (e.g., similarity of duties, skills, benefits, interchange or transfer of employees, promotional ladders, common supervisor, etc.), wages, hours and other working conditions of the employees involved the history of collective bargaining and the desires of the employees. The Board may determine a unit to be an appropriate unit although some other unit might also be appropriate.
Bargaining unit(s) shall not include statutory exclusions as defined in ORS 663.005(3)(a) through (i).
