I'm certainly in this category. However, when dealing with, say, a lab instrument or technique, I am extremely shrewd, objectively sorting out any issues and why they might be occurring. Funny in that with people, they simply do not follow the rules in terms of fairness or even predictability.
I've had certain individuals be intensely undeservedly inappropriate with me. Supremely manipulative, deceitful, even abusive and just plain mean to serve themselves. What recourse do I have? This depends entirely on whom you are dealing with. If an individual is behaving inappropriately and they are in a position of authority, there may not be much recourse (depending on the situation). I've been in impossible situations and have LET another run over me badly. I have reasoned that if I'm extra-nice to them, then they'll leave me alone.....really does not work. Instead, it seems to give them permission to go further. Ouch.
Many bully situations entail an imbalance of power such that if we fight back, then we get the blame. This is seriously unfair and wrong, but it's oftentimes reality. My tact now is to avoid those who flagrantly violate. Just avoid them 'like the plague.' I simply do not have the wherewithal to combat their 'mind games' and must instead focus on what I need to do. I guess the moral is to work with those who are trustworthy.
There is a irony though.......I have personally met and worked with individuals who are considered to be really tough and hard to get along with. An example: I had a (former) professor who later become my boss. Gruff hot-tempered man and really strict! Many were leery of him as a result. But I learned that he was always fair and he really listened. He and I became not just good colleagues, but also close friends (yes, like a father figure). He had an element of predictability - I knew I could always count on him. I honestly do not mind 'tough' people, even those with big egos so long as they are fair.
Anyway, I know exactly what you all mean. And yes, acting confident (even if you're faking it!! !) makes a big difference.
