This report summarizes strategies San Francisco employers used to implement the nation's first law requiring paid sick days for all employees, based on interviews with a sample of businesses. Although employers faced three new policies that affected staff wages and benefits, they were able to implement the paid sick leave requirement with minimal impacts to their business. The report details employer responses to the law in their operations, staffing, employee benefit packages, and reporting requirements. By assessing employers' perspectives on the operational challenges of the law, the study provides lessons to inform future research and policymaking.
