The applicant trade union sought certification for a bargaining unit consisting of occasional teachers and supply instructors employed by the respondent school boards.
The Board considered whether supply instructors, who are unqualified persons appointed in emergencies, share a sufficient community of interest with occasional teachers to be included in the same unit.
Noting the evolution of collective bargaining practice and the functional similarities between the two groups, the Board found the proposed combined bargaining units to be appropriate and directed that certificates issue to the applicant.
