I'm not sure what you mean by "unenforceable." In all cases, the job is lost, and that is enforcement enough. It isn't a criminal issue, and I seriously doubt anyone has ever been arrested, but nothing can stop a lawsuit from being filed. Whether it is successful or not isn't the issue. Even if you win a lawsuit, you can still lose your savings and your home. So be careful with your signature, read the fine print, and be resigned to keep your word, and have no worries. Screw around, and you'll at the very least be terminated without a reference for however long you worked, leaving ugly conspicuous gaps in your resume. 9 times out of 10, an employer will hire the less competent but more honest individual. Once you lose your credibility, it's gone.
