Were you chastised a lot as a child over next to nothing? If so, that would explain why you react the way you do to people in authority.

I react in a similar fashion as I grew up in a dysfunctional home, and was always getting in trouble. Even today I freak out if someone in authority says 'I want to talk to you' to me as that's what my stepfather would say before chewing me up one side and down the other.

One thing I'm slowly learning is that I'm entitled to an opinion and so are you. Try to realize that and find ways to defuse situations so you can discuss things with your coworkers with less drama. I'm not criticizing you as I'm the same way, and I'm 60 years old.

There's a book about learning to stand up for yourself written from the point of view of the public shaming we see here in America where if you disagree with someone and have a business, people will put you out of business unless you grovel to them and admit you're wrong. I haven't read the book, but have heard it's interesting. I hope to buy it in the future as I'm sure I it would help me. Here's a link to it.
