The hearing examiner shall render a report and order within a reasonable time either dismissing the petition in whole or in part or clarifying the unit, determining requests for exclusionary designations, determining an appropriate unit and directing an election or designating the organizations to appear on the ballot. If the report and order establishes a bargaining unit different from that proposed, the hearing examiner may require the supplementation of the showing of interest forms or employee authorization forms prior to scheduling an election or certifying a bargaining agent by majority sign-up. The hearing examiner may also take other appropriate action.
