Karma doesn't always work this well, but when it does it's so satisfying.
It's funny how a workplace dynamic can switch so suddenly. As long as you keep your head down and do whatever is asked of you, you'll be fine. But the minute you stick up for yourself, you risk putting yourself in the line of fire.
