Union representation



ERB is responsible for determining when (and under what circumstances) public employees will be represented by a labor organization for purposes of collective bargaining with public employers. ERB’s responsibility includes determining what bargaining units are appropriate and for clarifying the scope of an appropriate unit. Requests that ERB take action with respect to a prospective or existing bargaining unit must be filed using the appropriate form below.

**Note: ERB forms are fillable, however, information is not automatically saved. We suggest to download the form, complete the form and save it, to ensure information populates correctly when filed.
