How to get your boss fired- petition?
I'd draft a letter for one page explaining why he or she needs to go.
Then on a seperate sheet of paper, include a survey like sheet with names, dates and a column that says "agree or disagree". It's important to get everybody and it looks more thorough if you get the one or two dissenters as well as the 99% of staff that thinks the boss should go.
However, you have to keep in mind, unless the company can select a qualified replacement, they won't fire your boss. Also, depending on the circumstances, the petition may not do anything...but, if it's a really intolerable situation, I'd strongly recommend giving it a try if all the employees feel the same way.
