I’d look for another job, you work for the worst kind of idiot.

Well, OP, I'd say that is good point in life to get every future order you get from your boss (this or another one) in writing. Always. With as many questions as you can fit, so when push comes to shove, it's their ass on fire, not yours.

"Shit rolls downhill." That is why it's great to be a boss: you can usually scapegoat your underlings for your fuck-ups.

People who get mad at someone for following their express orders should be dragged into the street and shot.

That’s why you get stuff like that in writing.

Always and I mean always get your boss or supervior to send job details in an email. or send to confirm said job. I have a boss that would not ever respond to emails he would come to my desk and verbally respond. So I would follow up with an email to the one he would not respond with, Per our coversation you want xyz completed: blah blah blah... Everytime its called the CYA email

Honestly it sounds as though neither of you should be in construction.
