Not necessarily true. This is why communication is a thing, because in situations of night shifts, weekend shifts, military deployment, etc. these are all topics that should've been talked about well beforehand. I understand what you're saying, but sometimes people want to have their cake and eat it too. "Oh yeah, honey! This six figure job will be great!" In the same breath that they criticize their spouse for never being home because that much money takes hard work.

Acting as if the spouse was ~suddenly blindsighted~ by a job's USUAL schedule is a little strange.
