This is a reference, not legal advice. Every rule links to its primary source — a statute, an ordinance, or the enforcing agency — so you can read the law rather than a summary of a summary. Ordinances change, and their exemptions and headcount thresholds are genuinely fiddly. Consult counsel before relying on any of it.
The single most useful thing to know before reading any of this: most US predictive-scheduling law is municipal, not statewide. New York City, Seattle, Chicago and Philadelphia each passed their own ordinance; the states around them did not. Oregon is the significant exception, having legislated statewide.
So "are we covered?" is a question about each location's address, plus usually a headcount threshold and an industry test — and a company can easily have one store covered and two not. The rules below are grouped by state because that is how statutes are published; the ordinance names tell you which city inside it they apply to.
We keep this current because our own compliance engine reads the same data. If you find something wrong or out of date, tell us at hello@weekwright.com — a correction to a primary source is welcome from anyone, customer or not.
