Upon the filing of a petition for election of collective bargaining representative or a unit clarification petition, Board staff intervene actively with the parties to seek to resolve any unit determination issues in dispute. Unit disputes are informally resolved in many instances; if unit issues are not informally resolved, then a panel of three Board members will decide the matter after a hearing and filing of briefs. In cases where petitions for election or decertification of a collective bargaining representative are filed, once unit issues are resolved, Board staff conduct representation elections, usually at the involved workplace.
