To change or not to change, that is the question.

I have been offered a job, with a different company to do what I was once trained to do in the Army.I was trained to be a diesel mechanic when I served for a little while, and when I got out noone would hire me because of the fact I wasnt ASE certified or didnt have my own tools.Now I have a job offer to go back and do the job I once trained for.Then on the other hand I also have this my current job at a printing company that isnt paying worth a damn, but I like the work......sometimes.I once made some good money for the printing company, but since I went from working nights to working days I no longer make the good money.In fact I make the same thing now that I did four years ago.Now with gas prices as high as they are now I cant make ends meet that well.Even though my wife just started working it still hard to make ends that well.I also just found out today they are going to hand a promotion to someone in the plant that has been there for awhile, and found out my name wasnt even on it.Being pissed off just the word for it, I pretty much just exploded and made them know I wasnt happy with that idea.Now I have to wait till Monday to talk to the plant manager about the promotion and my job offer with the diesel shop working on tractors.I havent done my old trade in years, and a old friend of mine is going to help me get the tools I need.If I dont get the promotion for press operator, I will drop my current job in a heartbeat.But if this other job doesnt pan out I will be shit out of luck.What I want to do is take a week off from my current job for vaction and try this job out without reprecussions.I just really dont know what to do.
