The applicant union applied for certification to represent a craft bargaining unit of stationary engineers employed at a sewage treatment plant, seeking to carve them out from an existing, broader industrial bargaining unit represented by the intervener.
The Board declined to exercise its discretion under section 6(3) of the Labour Relations Act to permit the craft severance.
The Board found that the stationary engineers did not have a separate community of interest, and that carving out a small unit would lead to undue fragmentation and potential industrial instability.
The application for certification was dismissed.
