The grievor, an electrician, filed a grievance alleging he should have been called in to shut off a fire pump on two dates, rather than plumbers or mechanics.
The matter proceeded by mediation-arbitration.
The Arbitrator found that at the relevant time, the Employer's established call-in procedure for fire pumps listed plumbers first and mechanics second, but did not include electricians.
Although the parties subsequently agreed to add electricians to the call-in order, the Employer acted in accordance with the procedure in place at the time.
The grievance was denied.
