In a grievance alleging discrimination and harassment, the union sought production of employment references provided by the Ministry to a third-party employer (Serco).
Serco and the Ministry objected, claiming the references were protected by case-by-case privilege under the Wigmore test.
The Grievance Settlement Board held that the references were arguably relevant to the union's bad faith allegations.
Applying the Wigmore test, the Board distinguished the peer-review context in Straka and found that the injury to the relationship between the Ministry and Serco did not outweigh the benefit of correctly disposing of the litigation, which involved public policy rights under the collective agreement.
The motion to quash the subpoena was denied, and production was ordered subject to confidentiality safeguards.
