Yeah, I think the post you replied to is confusing night shift with just rotating shift work. The fact that you get off at 7 am on Friday and have to switch your schedule around to be at work at 7 am on Monday is what everyone actually hates about night shift. Steady shift is an entirely different thing. Night shift stinks for many, but there's no messing up sleep when it's what you always do as opposed to rotating 3 shifts, or 2 on a 12 hour schedule.
With our 12 hour schedule, one weekend we worked FSS daylight, off on Monday, then you had to be ready to work night TWT. That was the tough part, which paid off in 2 weeks when you worked 4 daylight shifts and had 7 days off (technically 8 counting the hours) and back to night for 4 nights.
