Starting in January, the financial services giant will expand its paid parental leave policy for mothers and fathers to 20 weeks at full pay, plus another six to eight weeks for women who give birth and require medical leave. Full-time and part-time employees who have worked at Amex for at least a year are eligible. CNN adds: That's a big shift from the company's current policy of offering six weeks of paid leave for the primary parent plus another six to eight weeks for birth mothers who require medical leave. Secondary caregivers, meanwhile, have gotten just two weeks. Under the new policy, parents will also have access to a 24-hour lactation consultant. And mothers who go on business trips will be able to ship their breast milk home for free.
