Add Comment Question: Can a unionized employee be terminated by an employer for "Frustration of Contract" if no such clause exists in the Collective Agreement, or is the employer strictly bound to the language (or absence of the language) in the Collective Agreement? Answer: Frustration of contract is an employment term and is not required to be in a contract. Speak with your union representative about this if you have further questions about your specific situation.
