I was dismissed without notice for violation of a non-solict clause in an employment contract that I was intimidated into signing 14 months after I started

It depends on what you did. If you were soliciting clients from your employer, while you were still working there, that would be cause for dismissal, regardless of any contract. If you were not soliciting clients or if you did nothing wrong, then this has to be a termination without cause, which means that you get severance. Please call me to discuss.
