Section 11.21.2.38 - ACCRETION

A. The exclusive representative of an existing collective bargaining unit, may petition the board to include in the unit employees who do not belong, at the time the petition is filed, to any existing bargaining unit, who share a community of interest with the employees in the existing unit, and whose inclusion in the existing unit would not render that unit inappropriate.

B. If the number of employees in the group sought to be accreted is less than ten percent (10%) of the number of employees in the existing unit, the board shall presume that their inclusion does not raise a question concerning representation requiring an election, and the petitioner may proceed by filing a unit clarification petition under these rules. Such a unit clarification petition to be processed, must be accompanied by a showing of interest demonstrating that no less than thirty percent (30%) of the employees in the group sought to be accreted wish to be represented by the exclusive representative as part of the existing unit. No group of employees may be accreted to an existing unit without an election if the board determines that such group would constitute a separate appropriate bargaining unit.

C. If the number of employees in the group sought to be accreted is greater than ten percent (10%) of the number of employees in the existing unit, the board shall presume that their inclusion raises a question concerning representation, and the petitioner may proceed only by filing a petition for an election under these rules. Such a petition, in an accretion situation, must be accompanied by a showing of interest demonstrating that no less than thirty percent (30%) of the employees in the group sought to be accreted wish to be represented by the exclusive representative as part of the existing unit.
