"On April 17, 2020, Mayor Breed signed an amended version of the [San Francisco Public Health Emergency Leave Ordinance (PHELO)]. In addition, the San Francisco Office of Labor Standards Enforcement ... published a workplace poster, detailed guidance for employers in the form of FAQs (updated April 24, 2020) and a complaint form to be used by employees to address violations of the PHELO. The PHELO became effective on April 17, 2020, and will expire on June 17, 2020, or upon the termination of the COVID-19 public health emergency, whichever occurs first. The PHELO addresses the FFCRA's coverage gap by establishing minimum supplemental paid sick leave requirements for private employers with 500 or more employees worldwide, subject to certain limitations applicable to healthcare providers, emergency responders and collectively bargained employees."
