Sure, I could bring up such a law suit. How many of those $10/hour employees are going to? The intimidation exists, regardless. At-will employment is the reason why you have to be afraid for your job if you don't give up your credentials. Even if they don't fire you, you've negatively impacted chances of promotion and possibly put yourself on the top of the layoff list.
