The San Francisco Sick Leave Ordinance is often overlooked. The ordinance, that became effective February 5, 2007, requires employers to provide employees who work in San Francisco with one hour of paid sick leave for each 30 hours they work. This applies to all employees who work in San Francisco (more than 56 hours a year) regardless of where the employer is based. There is a cap of 40 hours of paid sick leave for employers who have less than 10 employees, and a cap of 72 hours for those who have more than 10 employees. This cap only applies until the employee uses it up. The employee can begin to accrue again. There is no annual cap for how much sick leave an employee can accrue or take. The ordinance requires employers to post the ordinance (clicking here will bring you to a printable poster) where it can be seen, to keep track of employees hours for the purposes of calculating paid sick leave, and to keep a record of these hours for four years in case of audit by the Office of Labor Standards Enforcement (OLSE).
