How does PERB determine what constitutes an appropriate "bargaining unit"?
Deciding which employees should be included in a bargaining unit is a case-by-case
determination in which PERB applies the criteria listed in section 20.13 of the statute to the
particular circumstances of the case. What might be determined to be an appropriate
bargaining unit for a very small city (all employees eligible for collective bargaining, for
instance, including police officers, office clericals and public works employees) might well
not be deemed appropriate in a large city, where application of the section 20.13 factors
might result in multiple units, each containing different types of employees.
