I have worked for a company for 6 years. The fired me yesterday for what they say is just cause. They won't tell me exactly what I did only that I lied on a statement. They gave me no severance at all. Do I have a case?

Unless the company can prove that you did something awful, this is a wrongful dismissal. In that case, you would be owed significant compensation. The good news is that these matters are usually quite simple to resolve. It is very important that you give us a call to discuss this at the number below.
