Add Comment Question: Can someone be fired for theft automaticlly, when they are in a union? Answer: Thank you for your question. In a non-unionized context, many times an employer will have cause for dismissal if they can establish that an employee committed theft. It may depend on the circumstances. However, if you are in a union, your best recourse is to speak with your local union representative, who will be able to discuss with you whether the union can file a grievance on your behalf.
