 What to do when your code is stolen?
RiderOfGiraffes: IANAL ...Generally, default contracts (those in effect if you don't explicitly have one) state that anything you do or produce while working for a company belongs to the company.Sucks, doesn't it.If that's the case where you are (and it varies from region to region, country to country) then you have no rights.  What you produced is theirs, and they can do what they like with it.  Whether this really does extend to removing your copyright statement or not I don't know, but you're not going to find out cheaply.My advice, for what it's worth, is to chalk it up to experience.  In two weeks you built something you could be proud of.  Looking at it another way, you've lost only two weeks of your time, been paid, and learned a valuable lesson.Don't produce something unless you know who has the rights, who's paying, and how much.The only other advice I can give is to write a letter "more in sorrow than anger" expressing your disappointment that they have appropriated your work, removed the credit, and have failed to acknowledge the effort you put into it.  You could include a comment that it's been an eye-opener, and experience that you intend to pass on to others.  See what response that gets.  Be careful not to make threats.  Be "saddened" by the incident.Remember, these are comments from someone without a stake in it, and any action you take is your own.  I still suggest you simply walk away, taking the lesson.
