I know he's your friend, but to lighten things up some for ya the "Assistant Chief Engineer" is not the "ACE". He's the "Ass Chief".
Friends or not if you don't activly seek a job in the hvac field if that's what you want to do you'll get left behind and be stuck where you are now. You survived before you got this job. And no you shouldn't be treated like **** like you are. That's not how it is everywhere.
