The applicant union filed a displacement application for certification to represent employees currently represented by the intervenor.
The responding party employer disputed the applicant's estimate of the number of employees in the proposed bargaining unit and gave notice under section 8.1 of the Labour Relations Act, 1995, but agreed the ballots should be counted.
The Board found the numerical difference between the parties' estimates was not significant and ordered a representation vote.
The Board dismissed the intervenor's objections based on an alleged breach of a court order and union constitution.
The Board also declined the employer and intervenor's request to delay the vote until after the seasonal lay-off ended.
Board Member Ronson dissented, arguing the vote should be delayed until the school year began.
