Why the down votes?
This is a serious suggestion; I don't know the exact situation in America but in Europe all trade unions have trained advisers looking at stuff like this every day.
Going to an union is a much more effective and cheaper solution than every employee talking to an employment lawyer on their own.
I would have guessed that most union reps consult lawyers when they finalize a contract and don't have the law background needed.
I think the best way to describe danish unions are that they are a mix of us unions (that i don't know that much about) and law firms for worker.
You just call them, explain your situation and hear what they say.
In general they give you a quick evaluation and then say: In order for us to help you, you need to be a member - the price is xxx pr. month - if you sign up now we will work on your case straight away, we also have an insurrance that covers lawsuits and some other benefits.

Don't American doctors and teachers have a union?
