The grievor was discharged following a physical altercation with a co-worker.
The union filed the grievance past the time limits set out in the collective agreement.
The employer raised preliminary objections regarding arbitrability due to the delay and the unsigned grievance.
The arbitrator extended the time limits under s. 48(16) of the Labour Relations Act, finding the delay was short and the grievance involved a discharge, despite the union's negligence.
On the merits, the arbitrator found the grievor was the aggressor in the altercation.
Given the seriousness of workplace violence and the grievor's lack of remorse, the arbitrator upheld a substantial penalty, substituting the discharge with a suspension without pay for the period prior to his reinstatement.
