Illinois scheduling laws
Illinois pairs Chicago's Fair Workweek Ordinance with statewide rules: One Day Rest in Seven Act and the new Paid Leave for All Workers Act (2024). Predictive scheduling is the centerpiece for Chicago employers in covered industries.
This is a reference, not legal advice. Every rule below 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. Consult counsel before relying on any of it.
2 of these 4 rules apply regardless of industry; 2 bind only certain sectors, and each one says which. Most US predictive-scheduling law is municipal, so where a rule comes from a city ordinance its name says so — a company can easily have one location covered and two not.
Chicago Fair Workweek — 10/14-day advance notice
Chicago Mun. Code §1-25Covered employers (100+ employees globally, 50+ in Chicago) in retail, hospitality, healthcare, manufacturing, and others must post schedules 10 days in advance (rising to 14 days). Industries vary slightly in coverage thresholds.
Applies to:RestaurantsRetailHealthcareManufacturing
In Weekwright: Publish-week locks the schedule with a timestamp; the audit log captures every post-publish change for predictability-pay calculation.
Predictability pay (Chicago)
Chicago Mun. Code §1-25-050Schedule changes inside the notice window trigger predictability pay — 1 hour additional wages per added shift or extended shift; up to 50% of cancelled shift wages for short-notice cancellations.
Applies to:RestaurantsRetailHealthcareManufacturing
In Weekwright: Every shift mutation is audit-logged with before/after state. Compute predictability-pay liability deterministically, not from manager recollection.
Statewide One Day Rest in Seven Act
820 ILCS 140/2All employees in Illinois must receive at least 24 consecutive hours off in every calendar week. Limited industry exemptions.
In Weekwright: MAX_CONSECUTIVE_DAYS preset to 6 BLOCKING enforces this. The conflict detector refuses to publish a 7-day streak in the same calendar week.
Paid Leave for All Workers Act
820 ILCS 192Effective January 2024 — all Illinois employees accrue at least 40 hours of paid leave per year, usable for any reason. 1 hour earned per 40 worked.
In Weekwright: Time-off requests cover both sick and personal leave types; the conflict detector blocks shifts on approved leave days regardless of the reason.
Primary sources
Read the law itself. These are the statutes, ordinances and agencies the rules above are taken from.
Illinois by industry
The same statutes read for one vertical, with the scheduling patterns that vertical actually runs.
Other states
Again, because it matters: this is not legal advice. It is a reading aid over primary sources, maintained by a software company rather than a law firm. It surfaces obvious gaps so you can act on them — it does not tell you whether a specific ordinance applies to your specific business. Consult counsel for that.
