(Bloomberg)—As the labor market tightened in 2018, organizations turned to one benefit in particular to attract and retain U.S. employees: Paid family leave. After Starbucks Corp. and Walmart Inc. extended paid time off to hourly workers in January, 18 more large companies followed suit. As a result, an estimated 4.8 million people had access to more generous paid leave benefits this year, according to data compiled by PL+US, a paid leave advocacy organization. Many employers, like General Mills Inc., increased the amount of paid time off available to new moms and added the benefit for new dads, too.
