San Francisco Mayor Ed Lee recently signed a first-in-the-nation ordinance to require private employers to compensate employees while on parental leave. The ordinance applies to employers with at least twenty employees who work in San Francisco. It requires employers to provide “supplemental compensation” to employees using California’s paid family leave benefits for new child bonding – bonding with a minor child during the first year after birth or placement through foster care or adoption. The new ordinance goes into effect on January 1, 2017, for employers with fifty or more employees. Employers with fewer than fifty employees will be phased in over the course of a year.
