Sourced lines: 1-hour PP, ½× lost hours, $40 / 9-hour rest, 20-minute grace
Pay lines are pinned to the City of Philadelphia Fair Workweek ordinance PDF and the two OWP HTML pages fetched 28 August 2026. The $40 / 9-hour rest line is in the PDF and the report-a-violation page; it is not in the 19 March 2020 predictability-pay explainer.
- City of Philadelphia Fair Workweek Law PDF — Phila. Code Ch. 9-4600. § 9-4603 Predictability Pay (1 hour add/move; ≥½× per scheduled hour not worked for subtract/cancel, including unused on-call). § 9-4603(2)(d) twenty-minute start/end grace. § 9-4604 Right to Rest: decline hours <9 hours after the previous day’s shift or during the 9 hours following a two-day-spanning shift; if worked, $40 for each such shift.
- OWP: Understanding Predictability Pay (19 Mar 2020) — employer-initiated schedule-change pay. Does not contain the $40 / 9-hour rest line.
- OWP: Report a Fair Workweek violation — “Failure to allow nine hours of rest or obtain consent and pay $40.”
Employer add inside 14 days, 8h @ $20 → $160 wages + $20 Predictability Pay
Cancel 4 scheduled hours @ $20 → +$40 (½ × 4h × $20), not hours worked
Last-out 22:00 / first-in 08:00 (10-hour gap) → $0 rest
Last-out 22:00 / first-in 06:00 (8-hour gap) → +$40 flat (still $40 at a $30 rate; not Chicago’s extra quarter)
Subtract/cancel is ½× after posting for any notice inside 14 days — there is no Chicago MCC 6-110-050(b)(2) extra 50% band that applies only with less than 24 hours’ notice. Schedule-change exceptions (employee written request, voluntary swap, operations cannot begin or continue) turn Predictability Pay and the ½× line off — toggles default off so those premiums apply. The $40 rest line still follows the punches if the short-rest shift is worked.
Coverage is a label, not a fake headcount check
§ 9-4601 Covered Employer: a Retail Establishment, Hospitality Establishment, or Food Services Establishment that employs 250 or more employees and has 30 or more locations worldwide, including chain establishments and franchises counted in the aggregate. The employee’s job duties must involve retail trade, food services, or hospitality services inside Philadelphia. This calculator does not gate the math behind a checkbox for 250 or 30 locations.

Out of scope
- Chicago 1.25× entire next shift (MCC 6-110-070) and NYC $100 clopening

- Seattle / Oregon 1.5× only for hours inside a 10-hour rest window
- Offer of work to existing employees (§ 9-4605) as a computed pay line
- Headcount / location-count eligibility as a calculator gate
- Ticketed-event, hotel-banquet, and 24-hour-after-posting correction exceptions as computed lines
