I want to tell my bosses the one thing I really want to tell them
What will you say to them?
I want to kick their asses.
It is wrong to tell your boss you want to kick their ass. Whether you like them or not, vocalizing that is bad.
That is fine, it's life.
You will get fired if you do this to your bosses. Grievances you have with your bosses should be handled through the proper channels.
