Sourced lines: 1 / 2 / 4 hour predictability pay; unused on-call 2 or 4; no clopening
Pay lines are pinned to L.E.C. § 42.4 on Amlegal and the OLSE hub / rules / FAQ bodies fetched 28 August 2026. The workplace poster states schedules, predictability pay, and on-call; it does not reprint the 1/2/4 hour table.
- SF.gov FRERO hub — “If changes are made to an employee’s schedule with less than seven days’ notice, the employer must pay the employee a premium of 1 to 4 hours of pay at the employee's regular hourly rate (depending on the amount of notice and the length of the shift).”
- L.E.C. § 42.4 (Amlegal) — (c)(2)(A) 1 hour with <7 days but ≥24 hours; (B) 2 hours with <24 hours for a shift of four hours or less; (C) 4 hours with <24 hours for a shift of more than four hours. (d) unused on-call 2 or 4 hours by shift length.
- OLSE FRERO Rules (29 Jan 2016; L.E.C. citations updated) — Rule 5.1 restates the <24h 2-hour / 4-hour split.
- OLSE FRERO FAQs (updated 8 Aug 2025) — chart: <7 days and ≥24 hours / any length / 1 hour; <24 hours / 4 hours or less / 2 hours; <24 hours / more than 4 hours / 4 hours.
- OLSE FRERO workplace poster — schedules + predictability pay + on-call; not the 1/2/4 table.
Change with 30 hours’ notice, 8h @ $20 → $160 wages + $20 (1 hour)
Change with 12 hours’ notice on a 4-hour shift @ $20 → +$40 (2 hours)
Change with 12 hours’ notice on a 5-hour or 6-hour shift @ $20 → +$80 (4 hours — both are more than four hours under § 42.4(c)(2)(C))
No clopening / rest-between-shifts line
A 5-hour shift with 12 hours’ notice is not 2 hours of pay. The cutoff in the code is four hours or less versus more than four hours. Schedule-change exceptions in § 42.4(e) (operations cannot begin or continue, another employee’s unscheduled absence, mandatory overtime, employee-requested change or swap) turn the 1/2/4-hour and unused-on-call lines off — toggles default off so those premiums apply.
Coverage is a label, not a fake headcount check
The OLSE hub: chain stores with at least 40 formula retail establishments worldwide and 20 or more employees in San Francisco, as well as their janitorial and security contractors. § 42.4(g) applies the section to property services contractors as to work performed in San Francisco at a covered formula retail establishment. This calculator does not gate the math behind a checkbox for 40 stores or 20 SF employees.
