A rotating shift schedule is one where employees cycle through different shifts over time — a week of mornings, then a stretch of evenings, then a run of nights — instead of being locked to the same block every day. If your operation has to be staffed around the clock but you don’t want the same handful of people permanently stuck on nights, some form of rotation is usually how you spread that burden. This post is the plain-English version: what the term means, the two directions a rotation can turn, how fast it should turn, and where the well-known named patterns fit in.
I’ve built scheduling models for manufacturing plants and 24/7 operations for a couple of decades, and rotation is one of those topics where the folklore and the research don’t always line up. So I’ll keep the claims modest and point you at the source material where it matters.
