COVID Return to Work Guidelines: Isolation, Pay, and Accommodations

California’s COVID return to work guidelines no longer come from a dedicated Cal/OSHA regulation. Those COVID-specific rules expired on February 3, 2025, and the current standard is the California Department of Public Health’s isolation guidance: if you tested positive and had symptoms, you can go back to work once at least 24 hours have passed with no fever (without fever-reducing medication) and your other symptoms are mild and improving.¹ If you tested positive but never developed symptoms, no exclusion from the workplace is required at all. Your employer may layer additional rules on top through its own safety program, but the statewide mandate that once set fixed exclusion periods is gone.

When You Can Return After a Positive Test

The operative standard comes from CDPH, which Cal/OSHA now points employers to on its guidance pages.¹

If you had symptoms, stay home until at least 24 hours have passed with no fever (and no fever-reducing medication in your system) and your other symptoms are mild and improving.
If you tested positive but had no symptoms, you are not required to stay out of the workplace. If symptoms show up later, the 24-hour fever-free rule starts from that point.
If a local or state health officer has issued a specific isolation or quarantine order that covers you, that order controls and you cannot return until it is lifted.²

Under the old Cal/OSHA regulation, these were enforceable mandates. Now they function as the baseline that employers should follow through their Injury and Illness Prevention Program when COVID-19 is an identified workplace hazard. An employer who ignores the standard entirely and pressures a visibly sick worker back onto the floor can still face enforcement under California’s general workplace safety law, but the path is less direct than it used to be.

Masking After You Return

CDPH recommends that anyone who tested positive wear a mask indoors around other people for 10 days. Day zero is the date your symptoms began, or the date of your positive test if you never had symptoms.³ You can stop masking early if you get two negative antigen tests taken at least one day apart.

This is now a recommendation rather than a Cal/OSHA mandate, but your employer can still require masking as a workplace safety measure through its IIPP. If the policy is in your employer’s safety program, refusing to mask during the 10-day window can be treated as a safety-rule violation.

Working From Home During Isolation

Nothing in California law requires your employer to let you work remotely while you isolate after a positive test. If your work can be done from home and your employer agrees, telework during isolation keeps you from burning through paid leave. But creating a remote arrangement for isolation alone is not an employer obligation.

The analysis changes if you have a disability. Under the Americans with Disabilities Act and California’s Fair Employment and Housing Act, telework can qualify as a reasonable accommodation when a COVID-related condition meets the legal definition of a disability.⁴ That is a different legal track than ordinary isolation.

Getting Paid While You’re Out

There is no COVID-specific paid leave in California right now. Supplemental Paid Sick Leave expired on December 31, 2022, and the separate Cal/OSHA “Exclusion Pay” obligation ended in February 2023.⁵ You rely on the leave you already have.

California Paid Sick Leave is the main option. If you have worked for your employer at least 30 days, you earn one hour of paid sick leave for every 30 hours worked, with a minimum of 40 hours (five days) per year. This leave explicitly covers self-isolation tied to potential COVID-19 exposure.⁵ Beyond that, you may use vacation or general PTO, and your employer can require you to use those. The absence may be unpaid once your paid leave runs out, unless another protection applies.

One distinction worth keeping straight: using accrued paid sick leave is the employee’s choice. Your employer cannot force you to drain your sick leave bank for a COVID absence. Vacation and general PTO are different; those your employer can require you to use.

What Your Employer Can Still Require

Every California employer has to provide a safe and healthful workplace under Labor Code section 6400, and that duty did not disappear with the COVID-specific rules.⁶ If your employer identifies COVID-19 as a hazard in your workplace, it must evaluate and correct unsafe conditions through its Injury and Illness Prevention Program.⁷

In practice, that means an employer can still require you to stay home while symptomatic, mask for 10 days after a positive test, or submit documentation of your return date. Those requirements come from the employer’s own policy now, not a statewide regulation, but they can be enforced like any other workplace safety rule.

What your employer is no longer required to do, as of February 2025, is a shorter list but worth knowing so you don’t operate on outdated assumptions:⁸

Individually notify employees of close contacts in the workplace.
Provide free COVID testing after a workplace exposure or during an outbreak.
Apply the fixed exclusion periods that the old regulation imposed after a positive test.
Follow the specific outbreak protocols that once required weekly testing when three or more cases appeared in a group within 14 days.
Pay exclusion pay to workers kept out of the workplace due to COVID exposure.

If you were sent home under the old rules and expected exclusion pay or employer-paid testing, those are gone. If your employer voluntarily keeps a stricter policy, the policy is enforceable as a workplace rule, but it is not required by state law.

Protection If You Speak Up or Refuse Unsafe Work

Reporting a COVID case, flagging unsafe conditions, requesting protective equipment, or filing a safety complaint is protected activity. Federal law prohibits retaliation under Section 11(c) of the Occupational Safety and Health Act, and federal complaints have to be filed within 30 days of the retaliatory action.⁹

California adds a second layer. Labor Code section 6310 prohibits retaliation against employees who complain about health and safety conditions, report work-related illnesses, or take part in safety proceedings. Section 6311 gives you the right to refuse work that would violate an occupational safety standard and create a real and apparent hazard. Both apply to COVID-related situations. Termination, demotion, or similar adverse action tied to protected activity can be challenged.

Long COVID and Return-to-Work Accommodations

A standard infection that clears in a few days usually does not trigger disability obligations. Long COVID is a different situation. When symptoms like brain fog, chronic fatigue, joint pain, or shortness of breath persist and substantially limit a major life activity, the condition can qualify as a disability under the ADA and FEHA. Your employer then has to engage in an interactive process to identify a reasonable accommodation, unless doing so would cause undue hardship.⁴

The EEOC has pointed to accommodations that often fit long COVID symptoms:

For brain fog: a quiet workspace, noise-cancelling devices, or uninterrupted work time.
For headaches: alternative lighting and reduced screen glare.
For joint pain or shortness of breath: rest breaks, or removal of physically demanding tasks that aren’t essential to the job.
For fatigue: a flexible schedule or a telework arrangement.

Your employer gets to choose among effective accommodations. You can ask for telework, but if another option works equally well, your employer can offer that instead. The fact that you worked from home during the earlier phases of the pandemic does not entitle you to telework now as a permanent accommodation. You have to show a current disability-related limitation that requires it.⁴

When COVID Qualifies for FMLA or CFRA Leave

A mild case that resolves in a day or two typically does not qualify for job-protected leave under the Family and Medical Leave Act or the California Family Rights Act. These laws cover “serious health conditions,” which generally means an overnight hospital stay, or incapacity lasting more than three consecutive days combined with ongoing medical treatment.¹⁰

A severe COVID case that puts you in the hospital, or keeps you out of work for more than three days with follow-up care prescribed by a doctor, likely meets the threshold. Long COVID with recurring episodes of incapacity that require treatment at least twice a year can qualify as a chronic serious health condition. If your situation fits, you are entitled to up to 12 weeks of unpaid, job-protected leave per year, and your employer must maintain your health insurance during the leave. Eligibility requires that you have worked for your employer for at least 12 months and logged at least 1,250 hours in the year before leave begins.
