Fired the day after I gave 2 weeks notice

I was fired the day after I gave my notice at the law firm I worked for in Washington State. I am told this is illegal. What type of action, if any is avaible to me and what are the possible remedies?

Since you used to work for a law firm, then you know that your first step is to consult personally with your own retained attorney. Still, assuming Washington law is the same as California's, you did not suffer any unlawful termination.
