Back in February 2024, I visited a client's warehouse in Fontana — 120,000 square feet, two shifts, about 60 people on the roster. The warehouse manager, Zhao, flipped through his Q1 schedule and said something that stuck with me: "Lao Mi, the call-ins this year are way up."
So we did the math together. Before SB 616, each employee got 3 days of paid sick leave a year — 24 hours. After the law took effect, it became 5 days or 40 hours, whichever is greater. That's 16 extra hours per person. Multiply by 60 people and you're looking at 960 hours a year — half a full-time position, gone. And those 960 hours won't spread out evenly. They'll hit you during flu season and peak season, the weeks you're already short-staffed.
Here's my verdict up front: this is not an HR paperwork problem. It's a scheduling problem, a temp-labor budget problem, and an attendance-policy problem. Any California warehouse still running its labor plan on the old numbers is covering shifts with duct tape.
What the law actually says
SB 616 was signed by Governor Newsom on October 4, 2023, and took effect January 1, 2024, amending the Healthy Workplaces, Healthy Families Act. The essentials, which every warehouse scheduler should have memorized:
The floor moved to 5 days or 40 hours, whichever is greater. The old floor was 3 days or 24 hours. There's a subtlety most people get wrong: a six-hour-shift employee who uses five sick days burns only 30 hours, so they keep 10 hours on top of the 40-hour floor. An eight-hour-shift employee burns the full 40. Part-timers effectively get more days — so track sick leave in hours, never in days.
Accrual didn't change: one hour of sick leave for every 30 hours worked. Alternatively, an employer can front-load the full 40 hours at the start of each 12-month period and skip accrual and carryover math entirely.
Use threshold: employees must work for the same employer for 30 days in California and complete a 90-day employment period before they can use accrued sick leave.
Caps: the total accrual cap rose from 48 hours (6 days) to 80 hours (10 days); annual use is capped at 40 hours (5 days).
No size exemption. There is no "10-employee threshold" — the law covers employers of all sizes, including full-time, part-time, and temporary workers.

The real scheduling impact comes down to three things. First, your absence buffer has to be rebuilt from scratch. Zhao eventually remodeled his planned absence rate at 5 days per head per year and keeps an 8-to-10-person on-call backup roster through peak season (September to December), with the roster cost baked into the labor budget. Second, part-time and temp sick-day usage is harder to forecast because the hours-to-days conversion differs for every worker. Third — and this is the one most operators miss — your attendance policy has to be rewritten.
What happens when sick leave and a workers' comp claim collide?
The classic warehouse scenario: a picker tweaks his back, burns two weeks of paid sick leave, and only then files a workers' compensation claim. The sick-leave request sits in the system while the injury report lands two weeks late, and HR and the safety lead blame each other.
Understand the two tracks. Sick leave is sick leave; a workers' comp filing is a separate process. The moment a supervisor learns an injury might be work-related, the first move is an incident report and the workers' comp process — not "just use sick leave for now." Sick-leave pay and temporary disability benefits can't be double-collected, and how already-used sick hours get treated depends on company policy and labor counsel.
My practical rule for warehouses: any suspected work injury gets an incident report and a comp filing started within 24 hours. OSHA 300 recordkeeping and California's claim-reporting timelines are independent obligations — don't blend them into one messy ledger. Letting sick leave "hold the line" while nobody files anything is how audits and denied claims happen.
Whose dime does the temp's sick leave come from?
California's law covers temporary workers too — 30 days with the same employer triggers it. Warehouses run heavy on staffing-agency labor during peak, so the question is real: who pays for those 5 days or 40 hours?
In practice, the obligation follows the employer of record — usually the agency that issues the paycheck and handles tax reporting. But under a joint-employer arrangement, liability can land on both sides, depending on the contract and the actual working relationship.
Three pieces of advice. First, pull out your staffing contracts before peak season. The allocation of sick-leave obligations needs to be in writing — add an amendment if it isn't there. Second, get written compliance confirmation from the agency: how many workers it covers and under what standard. Third, budget honestly. Once agencies comply, that cost gets passed through into their hourly rates sooner or later. Squeeze rates so hard the agency can only stay profitable by skirting the law, and the joint liability will come back to your door.
Can you still dock points for sick-day absences?
Many warehouses run attendance-point systems: two points for a no-call no-show, one for a late arrival, termination at twelve. After SB 616, that system needs surgery.
California law bars two things clearly: employers cannot require an employee using sick leave to find their own replacement, and cannot retaliate against or penalize an employee for lawfully using sick leave. Plain English: legally protected sick leave can't cost points, can't be labeled "unexcused," and can't show up as a negative performance review.
My verdict: split attendance into two ledgers. Sick leave gets its own ledger — protected by law, recorded but never penalized. Everything else goes in the other one. California also requires pay stubs to show each employee's available sick-leave balance, and your system needs to track sick leave separately from personal days and vacation. When auditors come, a pay stub without a sick-leave balance line is an easy catch.
Compliance checklist (print it, check it off)
- Employee handbook: update sick leave to "5 days/40 hours per year, whichever is greater"; remove the old 3-day/24-hour language.
- Timekeeping system: accrual at 1 hour per 30 hours worked; total cap 80 hours/10 days; annual use cap 40 hours/5 days; 90-day waiting period.
- Pay stubs: confirm every stub shows the employee's available sick-leave balance.
- Attendance policy: sick leave tracked separately — no points, no "unexcused" counts.
- Staffing/temp contracts: sick-leave responsibility in writing; get the agency's written compliance confirmation.
- Scheduling model: rebuild the absence buffer at 5 days per head per year; keep an 8-to-10-person on-call backup roster through peak (scale to your site).
- Sick-leave/workers'-comp handoff: train supervisors — suspected work injury goes to incident report and comp filing first, never "sick leave will cover it for now."
- Local ordinances: check whether your city or county has stricter leave or labor rules than the state; confirm against official sources for the latest policy.
Tomorrow morning before shift start, open your schedule and your HR system and check three numbers: is the sick-leave cap in the system still 24 hours; does the pay stub show a sick-leave balance line; is sick leave still costing points in your attendance policy? Get those three right, and SB 616 won't be the thing that blows up in your face.
