San Francisco’s 4-year-old, mandatory sick-leave law has gained wide acceptance among employees and their bosses, a new study by the Institute for Women’s Policy Research says.

The voter-approved law, the only one of its kind in California, gives workers one hour of paid sick leave for every 30 hours on the job. Workers can accrue up to five days at any given time at companies with less than 10 employees and nine days at any given time at those with more than 10.

Surveys of 700 employers and 1,200 employees by the Washington institute found that two-thirds of employers support the San Francisco law, and only 1 in 7 employers complained that it affected their profitability.”
