Employer breached collective agreement by using non-union workers despite corporate restructuring making them shareholders.
The applicant union referred a grievance to the Board alleging that the respondent employer breached the collective agreement by employing non-union members to perform bargaining unit work.
The employer argued that following a corporate restructuring, the non-union employees became shareholders and directors, and thus fell within the 'owners and managers' exception in the collective agreement.
The Board found that the employees' duties remained unchanged and did not involve supervising the work of others.
The Board upheld the grievance, finding the employer in breach of the union security and hiring provisions of the collective agreement.
