The applicant union referred a grievance to arbitration under section 124 of the Labour Relations Act, alleging the respondent employed non-union workers without referral slips.
At the hearing, the respondent argued the applicant should be restricted to the grievance as filed and precluded from raising interpretation issues not explicitly pleaded.
The Board ruled that a grievance need only particularize the factual allegations and reference the relevant collective agreement provisions, and the respondent is not entitled to particulars of the applicant's legal theory.
The matter was adjourned to be heard alongside a related grievance.
