Fair workweek
Also called: predictive scheduling, secure scheduling
Fair workweek is the name given to laws that require employers to publish schedules a set time in advance and to compensate staff when shifts change late. They exist in a number of US cities and states, and similar ideas appear elsewhere under other names.
What such rules typically cover
Advance notice of the rota, predictability pay when a shift is changed or cancelled late, a minimum rest gap between shifts, and a right to decline a clopening. The specifics differ substantially between jurisdictions.
Who they usually apply to
Commonly retail and food service above a certain size. Small independent venues are often outside the scope, which is why many operators have never heard of the term until they open a second site or cross a headcount threshold.
Worth doing regardless
Publishing two weeks ahead and keeping a rest gap are good practice whether or not anyone requires it. Both reduce no-shows and churn, and they cost nothing except planning further ahead.
