Division I - Bargaining Agents and Units — Examination of records

For the purposes of determining whether the majority of the employees in a unit consist of members in good standing of a trade union or whether a majority of them have selected a trade union to be their bargaining agent, the board may make the examination of records or other inquiries that it considers necessary, including the holding of the hearings or the taking of the vote, that it considers expedient, and the board may prescribe the nature of the evidence to be provided to the board.
