They don't really care about the people that work for them nor the people around them. It doesn't take long to recognize those that have a lack of integrity or pride. Those are the people that, often times, you have to back out their door so you're not stabbed in the back on the way out. They are the kind that let someone else take the hit for something they did. I can't believe it was that long ago.
Some people take admitting a mistake as being weak and imperfect.
Whoa is me, if we were all perfect we wouldn't be here on earth. I firmly believe if you have pride in yourself, you wouldn't have any breach in integrity. It's hard to be ethically or morally corrupt if you have self-esteem and pride within yourself. There are times I've screwed up at work and as much as I didn't want to admit it, I did. There - I would get it over with, internalize it for a while and then get on with my life.
