A petition for reconsideration of an agency-established bargaining unit may be filed by an employee organization, public employer, or an employee of the public employer. This petition may be filed only in combination with a certification petition. Rules 621-4.1 (20), 621-4.2 (20), 621-4.3(20) and 621-4.4 (20) shall apply. A petition for reconsideration of an agency-established bargaining unit covering state employees may not be filed for at least one year after the initial unit determination. The agency may dismiss the petition for unit reconsideration if the petitioner fails to establish that the previously determined bargaining unit is inappropriate.
