Two years ago I did the same thing for much the same reason. I was walked out of the office about 4 hours after I gave notice and received the notice of their intent to sue the next morning. It turns out that they had no basis for a lawsuit and would have probably lost (they were claiming "inevitable disclosure of proprietary information" as the reason, which apparently has never been won in Mass.) but it would have cost me a bundle. To make matters worse I was entitled to some fairly valuable stock options (I know, I should have exercised before submitting my resignation) which they threatened to withhold based on a secret (not communicated to anyone) that allowed them to withhold options basically for any reason they want. In any event, it took three months to work out a settlement. Luckily my new company picked up the legal bills but I was unemployed without the ability to file for unemployment during that time. What a pain.
