If a company wants to hire me, do I need an attorney to review the proposed employment agreement?

Absolutely! I cannot tell you how many individuals have come to me after signing an employment agreement, the terms of which the person did not understand. Even if the company says that it will not entertain any changes to the document, you owe it to yourself to find out exactly what that proposed agreement says. As former general counsel of a New York Stock Exchange company, I am very familiar with employment agreements and the provisions that you should insist upon in such an agreement.
