Once you take charge and get everyone talking, you will find that the problem is not as bad as everyone predicted.
It's tempting, but you'll only make a bad situation even worse if you allow your frustration and anger to be unleashed. If you do, they'll only retaliate and hit the ball back into your court, and you will probably end up in an angry rally that benefits no one.
If you want it, ask for it. It's that simple. You might not get what you want, but at least you tried.
