I walked away from my job nearly a year ago as it was driving me potty. Having a 3 year old and a one year old child made me realise i'd rather be a happy daddy than a nutcase psychotic stress head. My kids wouldn't remember in years to come that i'd slaved in a job i hated, just that i was a short tempered butt head! Ironically the department that i headed was closed and moved 100 miles away (after 2 years of management swearing blind they weren't going to do it!).
Never looked back
Sounds like they've done you a favour... probably dosen't feel like it now... but they have!
And As my dear old Granny used to say...
"F**k 'em... F**k 'em all!
She had a way with with words did Granny!
