Gregory Steshenko was fired from Microsoft because users on a elist he was on complained. Check out the USENET post (I saw it in alt.comp.acad-freedom.talk) but it was crossposted to zillions of groups.

This sort of thing happens all the time, actually. A close friend of mine was put on an 'employee improvement plan' (the first step to being fired, actually) because she read/posted to rec.pets.cats. Upon closer examination by her grandboss and subsequent review of her actions before, during and after the plan, it was determined that the action was taken for political reasons. (ie: her boss was looking for a reason to get rid of her because they had a personal conflict). In other words, if they want to fire you, they'll look for a reason. I could be fired for sending this message, if someone wanted to push the issue and my bosses didn't like me. As it is, they do like me, and I do a very good job, so the worst that would happen (first iteration) is an official direction to stop contributing to the cypherpunks list from my work machine. (non-work related use of my government machine.)
