The union filed grievances alleging that the employer violated the collective agreement by refusing to hire the grievor, a union president, at various non-nuclear construction sites.
The employer refused to hire the grievor on the basis that he was a security risk, citing his 1975 criminal conviction for conspiracy to export arms and a 1982 arrest at the U.S. border involving the smuggling of aliens.
The Board dismissed the grievances, finding that the union failed to prove the employer acted unreasonably, arbitrarily, or in bad faith in assessing the grievor's reliability.
The Board also held that even if the Canadian Charter of Rights and Freedoms applied to the employer's employment decisions, the refusal to hire based on security concerns related to criminal conduct did not violate the grievor's constitutional rights.
