What would your position be if it were a left-wing business owner (there are plenty) and an employee who was an active Freeper that posted on company time?
I'd say keep him there. They more he angers the other guys the more they are driven to vote against Kerry. The more votes for GWB the better.
Because Freepers are well-mannered, courteous, and kind, it would never become an issue. Mind you, and speaking as right-wing libertarian, it wouldn't matter what the employee's politics happened to be: If he was hurting efficiency and crimping my margins, he'd be out the door before he had a chance to clean out his desk, right-wing or not.
No Freeper would post on company time. ;)
Actually my position would be the same with a fellow Freeper. If it is excessive then we would talk and I would likely ask them to restrict the time they spent on the net. If it confined to breaks and down time then no problem, if it is interfering with your work then that is another thing.
But engaging coworkers in repeated arguments is not acceptable, it causes problems for everyone with in earshot, and like it or not we have to spend eight hours a day five days a week together. I will have a peaceful productive office if I have to break so heads to get it.
