Ok, wow, I just have to ask...
You don’t have to give names or specifics, but could give an example of the Evil Behavior? I am quite curious...
"Good Morning" to other female and to me, first thing "We have a problem!" or variations of that idea. Usually said problem didn't exist or was tempest in a teacup.
Staying behind after hours to help night shift people after pulling a normal day and asking for any kind of comp. time or even an acknowledgement that I did, usually a blank stare. There would be a followup remark to the effect (no matter what) that I took too long to do whatever.
Work out a minor problem for the head AutoCad guy who was very appreciative and even told evil incarnate so - get chewed out for it because she wasn't consulted but never bothered to take an interest in anything outside her little cube.
Telling me that whole departments did not want me around at all. My last day though with a few expected exceptions, got me lots of appreciation, handshakes, hugs (from some of the supposed offended), and a lot of sorry to see me go type statments.
"You will be trained to do all of these great advanced things". Never happened. Rules and policies changing on sometimes daily basis. Try to ask, learn, or anything - get brushed off. Later chewed out for not knowing about whatever the cause of the moment.
Know more about photography/photoshop than whole department put together but was not allowed to have Photoshop installed even though there were licenses. Never mind most people brought their digital camera photos for me to process and most of them could barely turn a camera on.
