The complainants alleged that the respondent terminated Margaret O'Connor's employment because she testified at an arbitration hearing, contrary to section 80 of the Labour Relations Act.
The respondent argued that an arbitration hearing is not a 'proceeding under this Act' and therefore section 80 did not apply.
The Ontario Labour Relations Board held that a board of arbitration or sole arbitrator is a statutory tribunal constituted under the Act, and thus a hearing before such a tribunal is a 'proceeding under this Act'.
Consequently, witnesses at arbitration hearings are protected against reprisals.
The complaint was adjourned sine die at the request of the parties.
