COVID-19 workplace safety

Physical distancing and capacity limits for businesses and activities are over. Guidance for specific industries has ended. But employers are still responsible for maintaining safe environments for employees and customers.

COVID-19 Prevention Emergency Temporary Standards

Employers must follow workplace safety and health regulations to protect workers. That includes protecting workers from COVID-19. Follow the COVID-19 Prevention Emergency Temporary Standards (ETS) to keep your workplace safe. They cover:

  • How to prevent infection in the workplace
  • What to do about outbreaks
  • How to keep employees safe in employer-provided transportation and housing

Visit Safer At Work to learn more about COVID-19 workplace safety.

Masking at work

Masks are required for everyone at work indoors, whether they are vaccinated or unvaccinated. Learn more about masking at work. Find details in the face coverings section of the FAQs about the ETS.

Returning to work after getting sick or exposed to COVID-19

Employers must ensure workers meet the criteria in the ETS before they return to work. When CDPH recommends shorter periods, employers must ensure workers meet the recommended criteria. Find details in the isolation and quarantine section of the FAQs about the ETS.

Workers that have COVID-19 symptoms

If a worker has symptoms, they can return to work when all of these are true:

  • Their fever is gone, and
    • They have no other symptoms, or
    • Their other symptoms are improving.
  • They get a lab test (antigen preferred) on Day 5 or later from when their symptoms began with a negative result.
  • They wear a well-fitting mask around others for 10 days, especially when indoors.

Otherwise, they cannot return to work until all of these are true:

  • At least 10 days have passed since their symptoms began
  • Their fever is gone for 24 hours 
  • Their symptoms have improved

This applies to everyone, regardless of vaccination status. It also applies to people who:

  • Had a previous infection 
  • Do not have symptoms

Workers that do not have COVID-19 symptoms, but test positive

If a worker does not have symptoms, but tests positive, they can return to work when all of these are true:

  • They never developed symptoms.
  • They get a lab test (antigen preferred) on Day 5 or later from their last exposure with a negative result.
  • They wear a well-fitting mask around others for 10 days, especially when indoors.

Otherwise, they cannot return to work for at least 10 days after they first tested positive.

This applies to everyone, regardless of vaccination status. It also applies to those who:

  • Had a previous infection 
  • Do not have symptoms

Workers that do not have COVID-19 symptoms, but had close contact

A worker who had close contact with someone who has COVID-19 but does not have symptoms must get tested on Day 5.

They can continue to go to work if all of these are true:

  • They are fully vaccinated and:
    • Boosted, or
    • Not yet eligible for their booster.
  • They do not have symptoms.
  • They test on Day 5 with a negative result.
  • They wear a well-fitting mask around others for 10 days, especially when indoors.

If they cannot get tested on Day 5, they can continue to go to work. They must do the following for 14 days after their last exposure:

  • Wear a mask
  • Maintain 6 feet of distance from others

If they are eligible for their booster, but have not received it yet, they can continue to go to work if all of these are true:

  • They get a lab test (antigen preferred) within 3-5 days from their last exposure with a negative result.
  • They do not have symptoms. 
  • They wear a well-fitting mask around others for 10 days, especially when indoors.

Otherwise, a worker can return to work when all of these are true:

  • They never developed symptoms. 
  • They get a lab test (antigen preferred) on Day 5 or later from their last exposure with a negative result.
  • They wear a well-fitting mask around others for 10 days, especially when indoors.

Workers that do not get tested can return to work after Day 10 from their last exposure.

Providing N95 respirators

Employers must provide unvaccinated employees with N95 respirators upon their request and at no cost. California is providing a one-month supply of N95 respirators to small businesses. Visit the Voluntary N95 Distribution page if your business would like to participate in this program.  

Employers may require employees to be vaccinated

An employer can require their employees to receive a COVID-19 vaccine as long as the employer:

  • Does not discriminate against or harass employees or job applicants on the basis of a protected characteristic, such as disability or national origin
  • Provides reasonable accommodations related to disability or sincerely-held religious beliefs or practices
  • Does not retaliate against anyone for engaging in protected activities, such as requesting a reasonable accommodation

Learn more about workplace safety and civil rights in the Department of Fair Employment and Housing’s FAQs.

Find details about reasonable accommodations in the U.S. Equal Employment Opportunity (EEO) Commission’s information about COVID-19 and EEO laws.

Request proof of vaccination

Employers requiring proof of COVID-19 vaccination status for employees or patrons should follow the CDPH Vaccine Record Guidelines and Standards:

  • Verify records through a private and confidential process.
  • Protect patrons from discrimination.
  • Do not create barriers to essential services or restrict access based on a protected characteristic.

Help employees get vaccinated

Employers can assist their employees by:

  • Coordinating vaccination events with provider partners
  • Hosting a mobile or pop-up clinic
  • Helping employees book appointments
  • Providing employees with educational resources
