Other things include super clickiness or even personality differences can be an issue of wether or not you can move up to your next role. If they like you, then you can move up. Also they document every little thing about you in this book and watch for patterns they want to fix about you. If you sense that you are not liked by management watch your back because they will write down anything they can in this book and talk about it in there management meetings and then figure out ways they can fire you.
