The union applied for certification of a tag-end bargaining unit including Operations Supervisors at Transit Windsor.
The employer argued that the Operations Supervisors exercised managerial functions and should be excluded under section 1(3)(b) of the Act.
The majority of the Board found that the Operations Supervisors exercised significant disciplinary powers, including issuing warnings and suspensions, which created a conflict of interest with bargaining unit employees.
The Board concluded that the Operations Supervisors exercised managerial functions and excluded them from the bargaining unit.
A dissenting member would have included them, finding their disciplinary role to be merely administrative.
