The Grievor, a regular employee, was on a 12-month temporary assignment.
During the assignment, he was summonsed to testify at a Grievance Settlement Board hearing for a colleague.
On the day he provided his summons to management, he was informed that the incumbent of the position he was backfilling was returning early, but his 12-month assignment would be honoured.
Ultimately, his assignment was not extended beyond the 12 months, while two other employees' assignments were.
The Union grieved, alleging the Employer's actions were tainted by anti-union animus and constituted a reprisal for his participation in the hearing.
The Board dismissed the grievance, finding no objective evidence of anti-union animus or discrimination, and accepting the Employer's operational reasons for its decisions.
