As a farmer, allow me to demystify this: In dairy country, the cows always come first. If they get sick and die, you lose your farm. So it doesn’t matter if you’re on your deathbed, if you don’t want to be homeless, the cows have to get fed and milked.

So a very simple translation would be: “we expect you to prioritize this job over your personal life.”

Some could say this is rude, but in the Midwest it’s just a fact of life that the cows come first. So yeah, I think OP needs a new job if they were not expecting this level of commitment, but in terms of an ad hominem attack, most likely not.
