I had the "pleasure" of dealing with a rabid democrat who we employed for a few weeks as a contractor. Got an earful the first week. Constant littany of BS.
There was an older, wiser contractor who worked onsite with this dim for the first week. A few times he noticeably winced when this fool opened his mouth. I think that he passed the word along...the 2nd and 3rd weeks were very.......quiet.
Personally, I didn't care, I just wanted to get the job done. Loudmouthed kid was just young. I think he assumed that since he knew everything that there was to know about the equipment we were installing (and he did, he was a whiz at it) ... that it translated into knowing everything about everything. Ditto my interest in having him teach me how the stuff worked.... felt the need to teach me about how politics worked, too.
I know the owner of the company pretty well. Will likely mention it the next time we go out for beers. "Don't can this kid, he's too good for that, but you might want to pull in the reins a little on him...."
Beware the left wing kooks as they will spend most of the work day plotting a suit, complaint or whatever to better their position. We had a Clinton supporter at our office who filed 4 sexual harassment complaints in 2 years. The person weighed around 350 lbs. Should have had hull numbers tattoed on her.
Best to avoid. Refer them to a competitor.
