I have this weird thing where my boss always writes me mean messages while I'm giving presentations, sometimes through slack and sometimes through the PM function on the video chat service we use. Sometimes the messages are only a little mean and sometimes they're pretty hostile. I can't tell if she's testing me to see how well I'd do in a pressure situation, or if she thinks she's being helpful, or something else entirely. She once said to me, "I have no empathy," so that's something to consider, too, I guess (and that was years before I agreed to work for her, so it's not like I wasn't warned!). Fortunately for me I have pretty thick skin, but even one of the other people in the company who I was talking to about it, was like, "Yeah that's not normal." If I didn't know better I'd think it was some form of attempted bullying, but I actually think she thinks it's her version of leadership. Gonna keep my mouth shut for now, which is something I'm inherently good at, and see if it lasts.
