I just don't get it

I've never worked full time in an environment like where I am now. People don't know how to resolve issues, are jealous of each other and just in general are unhappy people.

I don't understand. I just don't understand.

And when confronted they act like nothing is wrong and you are too sensitive from bringing it up. I so don't get it. Most people will talk with you and will resolve things but this group of people don't know how to do it.

Is it because they aren't Christians? Is it because they are old? Is it because they are women? Is it because they don't like me? Or what is it? I so just don't understand.
