The applicants applied to terminate the respondent union's bargaining rights for a full-time employee unit.
The union argued the appropriate unit included part-time employees and students, relying on a single document containing terms for both groups.
The Board found the document constituted two separate collective agreements and the full-time unit was appropriate.
The Board also denied the applicants' request to call all petition signatories to testify, citing the need to protect the secrecy of union membership under section 111(1) of the Labour Relations Act.
