I think this is great. People need to be aware of toxic behavior.
That said, though, I am often bugged at work because I am both an introvert and need to isolate my environment by wearing headphones. My team and others make assumptions that I'm unfriendly. It's frustrating and I've just started to go along with it and agree, "Yes, I'm wearing headphones because I am trying to shut you all out." The truth is, I am not mean, but I enjoy my alone time and need quiet to be productive.
Also, a lot of times, I've gotten frustrated with the leadership in the companies I've worked for over the years. Not every company- about half. And a lot of times in the past, I would vent to co-workers about this. I'd also be honest in reviews and surveys describing in detail what had been done incorrectly.
I don't think of myself as toxic, but because I've been so persistent at times talking about someone else failing to do their job correctly as a leader, people see me that way and as a pessimist.
I'm aware of this and have made attempts to be more optimistic. It has really helped out, but it's still tough. I often realize too late that I'm being down on something, even as I try to imagine a future where everything gets better.
I don't think I'm a jerk, bozo, or asshole, and I don't want to be any of those things. But, I also just want to be allowed to be who I am. I'm not always going to be sunshine.
