In an unfair labour practice and duty of fair representation complaint regarding the end-tailing of seniority following a corporate amalgamation, the applicant sought production of legal opinions and advice provided to the responding union.
The responding union claimed solicitor-client privilege over advice concerning strategy and negotiations, while conceding waiver regarding the legality of end-tailing.
The Board held that by pleading reliance on legal advice to establish the bona fides of its decision to end-tail seniority, the responding union impliedly waived privilege over all related legal advice, including recommended options and strategies.
Production of the documents was ordered.
