On Friday, San Francisco Mayor London Breed signed an emergency ordinance
into law that requires large employers to offer up to 80 hours of paid leave for various purposes related to COVID-19. Unless extended, the emergency ordinance will expire on June 17, 2020. The city's Office of Labor Standards Enforcement web page
provides additional information including FAQs
and a copy of the poster
that employers are required to use to notify employees about the new ordinance.
