Quick question, will appreciate at least one good response. Thnx!?

I'm afraid that your boss has the right to open or shut your door, she is your superior, and making a door stopper will only cause more friction and bad feeling. Working with colleagues and bosses it's best and more adult to keep all lines of communication open, and discuss anything that might be bothering you, and not resort to tactics like wedging a door open, which will get you into trouble with your boss.
