Substitute teachers in California do get benefits, but which ones depend on how much you work and for whom. Paid sick leave, retirement contributions, workers’ compensation, and legal defense from the district are automatic. Health insurance, unemployment during school breaks, and the more generous leave packages are conditional on hours, assignment length, or the district’s collective bargaining agreement.
What You Get No Matter How Little You Work
Four benefits attach to every substitute assignment, even a single day of work.
You accrue paid sick leave from your first hour. You’re enrolled in a public retirement system and contributions come out of each paycheck. You’re covered by workers’ compensation if you’re hurt on the job. And if a parent sues you over something that happened in the classroom, the district has to defend you.
California Government Code Section 825 requires school districts to defend employees against lawsuits arising from acts within the scope of their employment and to pay any resulting judgment or settlement, as long as you were acting within the scope of your job and cooperate with the defense. You need to report the claim to the district in writing at least 10 days before trial.1California Legislative Information. California Government Code 825
For a workplace injury — a hallway slip, a student altercation, anything in the course of your work — you have up to one year from the date of injury to report it. Once you do, the district must give you a claim form (DWC-1) within 24 hours. During the initial investigation while the district evaluates liability, you’re entitled to up to $10,000 in medical treatment.
Health Insurance Depends on Your Hours
Health coverage is the benefit most substitutes ask about and the one with the sharpest cutoff. Under the Affordable Care Act, school districts that qualify as applicable large employers must offer coverage to any employee who averages at least 30 hours of service per week, or 130 hours per month. Districts typically use the IRS “look-back measurement method,” tracking your hours over a prior period (often 12 months) to decide whether you qualify for coverage in the coming year.2Internal Revenue Service. Identifying Full-Time Employees
Long-term substitutes covering an extended leave or filling a vacancy for a full semester usually clear the 30-hour threshold. Day-to-day substitutes with irregular schedules often fall short. Some districts offer a basic plan to lower-hour substitutes, but you may have to pay the entire premium yourself.
If district coverage isn’t an option, you can enroll in a Covered California marketplace plan during open enrollment or within 60 days of losing other coverage. Premium subsidies depend on household income, with wages, tips, and unemployment compensation all counting toward the threshold.3Covered California. What Counts as Income
If you had district coverage during a long-term assignment that then ended, you likely qualify for COBRA. The district must notify the plan within 30 days of the qualifying event, you then get at least 60 days to elect COBRA, and 45 days from election to make your first payment. Coverage lasts up to 18 months after a job loss or reduction in hours.4U.S. Department of Labor. An Employee’s Guide to Health Benefits Under COBRA COBRA premiums can be steep because you’re paying the full cost the district used to subsidize, plus up to a 2 percent administrative fee, so compare it against a Covered California plan before electing.
Retirement Contributions Come Out Automatically
California requires substitute teachers to participate in a public retirement system, and contributions are deducted from each paycheck.
Substitutes performing credentialed teaching duties are covered by the California State Teachers’ Retirement System. For the 2025–26 fiscal year, members contribute 10.25 percent of their earnings under the CalSTRS 2% at 60 plan, or 10.205 percent under the CalSTRS 2% at 62 plan.5CalSTRS. Contributions Those rates apply whether you work one day a week or five. The contributions go toward a Defined Benefit pension that pays monthly income in retirement based on your years of service credit and final compensation.
Substitutes who work less than half-time may instead be enrolled in the CalSTRS Cash Balance Benefit Program, which works more like a 401(k): your contributions and the employer’s contributions earn a guaranteed interest rate, and you receive the balance when you leave the system or retire. If your assignment later increases to 50 percent or more of a full-time position, you automatically shift into the Defined Benefit program.6CalSTRS. Cash Balance Benefit Program FAQ Not every district offers the Cash Balance option, so ask yours.
The 60-Day CalPERS Election
If you previously held a classified (non-teaching) position covered by CalPERS and then move into a credentialed substitute role, you may be able to elect to stay with CalPERS instead of switching to CalSTRS. The election must be made within 60 days of your hire date in the new position, and you generally need to be an existing CalPERS member with at least five years of service credit.7CalPERS. Circular Letter 200-054-22 Changes to the Retirement System Election Eligibility Criteria If that describes you, ask your district’s HR office for the Retirement System Election form (ES 372) immediately. The window closes fast.
Paid Sick Leave and the Multi-District Trap
You accrue one hour of paid sick leave for every 30 hours worked, with a right to use at least 40 hours (five days) per year.8California Department of Industrial Relations. Healthy Workplace Healthy Family Act of 2014 (AB 1522) SB 616 doubled the previous minimum in 2024.9California Department of Industrial Relations. California Paid Sick Leave – Frequently Asked Questions
Two conditions apply before you can use accrued leave: you must have worked for the same employer for at least 30 days within a year, and you must have completed a 90-day employment period.8California Department of Industrial Relations. Healthy Workplace Healthy Family Act of 2014 (AB 1522) If you float between districts, each one is a separate employer with its own accrual clock. Hours at District A do not count toward your 90-day waiting period at District B.
You can use sick leave for your own medical appointments, a physical or mental health condition, or to care for a family member. Some districts offer more through their collective bargaining agreements, so 40 hours is the floor.
Bereavement Leave
Under AB 1949, California employers with five or more employees must grant up to five days of bereavement leave following the death of a spouse, child, parent, sibling, grandparent, grandchild, domestic partner, or parent-in-law. You’re eligible once you’ve worked for the employer for at least 30 days.10California Civil Rights Department. Bereavement Leave AB-1949 FAQ The law guarantees the time off but does not require the employer to pay you for it. You can use accrued sick leave or other paid time off to cover the days.
Unemployment During Summer and Winter Break
Whether you can collect unemployment during a school break turns almost entirely on one concept: “reasonable assurance.” If the district tells you it intends to offer you substitute work when school resumes, the EDD treats that as reasonable assurance and denies your claim for the break period, even if the district never gives you a specific return date.11CA.gov – Employment Development Department. FAQs – School Employees
You may still be eligible if:
- The district hasn’t offered or indicated you’ll have work next term.
- Any offer of future work is contingent on enrollment numbers, funding, or program changes.11CA.gov – Employment Development Department. FAQs – School Employees
- You earned enough from a non-school job during the base period to qualify for a claim on those wages alone.11CA.gov – Employment Development Department. FAQs – School Employees
If you’re denied, don’t assume the decision is final. The initial determination is sometimes wrong, especially when the “reasonable assurance” is vague or conditional. You can appeal in writing, typically within 30 days of the mailing date on the denial notice. Read the notice for the exact deadline.
Social Security and the 2025 Change
CalSTRS-covered positions generally do not withhold Social Security taxes, because California’s participation in Social Security for public employees runs through voluntary agreements under Section 218 of the Social Security Act, and many districts have not extended coverage to credentialed positions.12Social Security Administration. Section 218 Agreements A career spent substituting under CalSTRS can leave you with little or no Social Security benefit from that work.
Two federal provisions used to make this worse. The Windfall Elimination Provision cut your own Social Security benefit if you also had a public pension from non-covered work, and the Government Pension Offset could eliminate spousal or survivor benefits entirely.13Social Security Administration. Program Explainer – Windfall Elimination Provision The Social Security Fairness Act, signed on January 5, 2025, eliminated both. The SSA has processed retroactive adjustments back to January 2024 for affected beneficiaries.14Social Security Administration. Social Security Fairness Act – Windfall Elimination Provision (WEP) If you’re currently receiving a reduced Social Security benefit because of a CalSTRS pension and your payment hasn’t gone up, contact the SSA.
Check Your District’s Collective Bargaining Agreement
The benefits above are either statutory minimums or federal requirements. Individual districts often go further through collective bargaining agreements: additional paid leave, higher sick leave caps, jury duty pay that covers the gap between juror fees and your regular earnings, more favorable health insurance terms for long-term substitutes. These agreements are usually posted on the district’s website, and HR can tell you exactly what applies to your hours and assignment type. Make the call early in the school year, not when you need the coverage.
