The grievor, a warehouseman with 17 years of service, grieved a three-day suspension, a ten-day suspension, and his ultimate termination for workplace harassment.
The discipline stemmed from repeated incidents of aggressive and discriminatory behaviour directed at co-workers, particularly an accommodated worker.
The union argued the grievor's conduct was non-culpable due to underlying mental health issues and that the employer failed in its duty to inquire about a disability.
The arbitrator dismissed the grievances, finding no medical evidence to establish a nexus between the grievor's mental health and his misconduct, and no sufficient basis to trigger a duty to inquire.
Given the grievor's lack of remorse, repeated misconduct, and failure to heed a final warning, the termination was upheld.
