I wonder what the 'get a lawyer' threshold is? I mean, as a SysAdmin or a programmer, I've not seen a reputable company even threaten to sue someone for leaving... the very idea smacks of empty threats from a crazy, entitled consulting client. I mean, I'm all for getting lawyers when you need them, but if I've never seen it happen, is it worth the cost? Maybe it's something that is more common when people who deal with customers (sales) leave.
