I was terminated for

I was called on the phone by the CEO and VP FInance and told they were terminating me, e"ffective today, "because the situation at (client) has made you a liablility to the company. I have never even had a verbal warning about unsatisfactory job performance, let alone a clue that there was dissatisfaction with my work. There was a less than pleasant conversation with the client and the CEO, VP SW Dev, and VP Finance that I also participated in, but did not contribute. Conversation resulted in an offer of a resource from our company to the client for services to assist them with their SW. That was last Friday-I was fired today. I'm 57, female, have worked for the company 2.5 years. All satisfactory evaluations. Do i have a case?
