No. My Dad was like your DH, he worked shifts too. The shifts were always an excuse for the family to rotate between deathly silence, cowering fear and pretending to be jolly.
I was astonished when I found out that not everyone's house was like that, even with shift work. I was also screwed up, pretty much for life, by everything I learned from my parents' marriage
There's much value in kids learning manners, respect & consideration. But what you have there is a personality cult - they're not learning to consider others, merely that they are less important than their father's moods.
It would be nice to think your DCs weren't in for the same difficult fate as me & my sibs.
In my experience, staying together is NOT better for the children, if it teaches the children that you must suffer your fate and shut up about it.
What about your own self-respect & dignity, too? Wouldn't like to sing in the shower, even if your DH was tired?
Threaten to quit. If that doesn't work, do it.
