Clunk is right as is Etops, although I wouldn't necessarily couch it in those terms. If you resign on Friday, you've solved the problem that you expressed in post #1.
However, that doesn't mean a thing come Monday morning. There really are no dream jobs for the overwhelming majority of people, most of us have to put up with some form of tosser or other interfering in our daily lives. I quit the corporate world to get away form useless managers & faceless beauracracy & also to make a few quid.
Whilst it worked for me, I inevitably have to take it up the japside from customers once in a while; my new masters, so unless Holly Vallance is looking for a new Brazillian wax technician, I would think long & hard about the motivations before telling the boss to poke it up his hole.
