The applicant alleged discrimination when she was not awarded a non-bargaining unit position, which was instead given to a bargaining unit member.
The applicant's union, the United Steelworkers, filed a request to intervene.
The applicant opposed the request, citing confidentiality concerns and arguing the union had no authority over the non-bargaining unit position.
The Tribunal granted the union's request to intervene, finding that the union could be affected if the applicant was placed in the position, as it would displace the current bargaining unit member.
The Tribunal also directed the parties to make submissions on whether the successful candidate should be given notice of the application.
