The Employer brought a motion to strike portions of the Union's Statement of Particulars in a grievance arbitration, arguing that allegations dating back to 2011 violated the Board's 'three-year rule'.
The Union argued the rule breached natural justice or, alternatively, that exceptions should apply due to the grievor's fear of reprisal.
The Arbitrator upheld the validity of the three-year rule, finding it consistent with natural justice and the expedited arbitration process.
The Arbitrator struck the particulars relating to the alleged 2011 co-worker prank and subsequent ostracization due to the extreme delay and prejudice to the Employer.
However, the Arbitrator allowed evidence regarding the supervisor's 2011 response to the prank, finding it relevant to establishing the origins of the alleged recent pattern of harassment.
