The applicant trade union applied for certification in the construction industry.
An employees' association sought to intervene but failed to provide written evidence that employees had applied for membership, leading the Board to deny it status.
The respondent employer argued the application should be barred because the applicant had recently withdrawn a similar application.
The Board declined to impose a time bar, finding no evidence that the withdrawal was an attempt to avoid a representation vote defeat.
The Board determined the appropriate bargaining unit and referred the matter to a Board Officer to inquire into the list and composition of the unit.
