The Bill and Melinda Gates Foundation says it will reduce its paid parental leave program by half -- to help the nonprofit run more smoothly.

On LinkedIn, Steven Rice, the head of human resources at the foundation, wrote that the paid leave program was more disruptive than expected when the policy was announced three years ago. The Gates Foundation had offered a year of paid leave; this move would reduce it to six months.

"On one team, 50 percent of the staff was either on leave or staffed by those in backfill positions, making the regular work of the foundation far more difficult than expected,” Rice wrote.

The foundation made headlines in 2015 when it announced it would offer parents a year off to care for their newborn babies. The foundation was on the cutting edge here in the U.S., which is the only industrialized country that does not require paid parental leave.

The Gates plan was also cutting edge because it offered the benefit to both moms and dads, with the goal of greater gender equity in the workplace and in families. Woman and men were encouraged to take the time to care for their kids.

Women were more likely to take the full year than men; 77 percent versus 41 percent of men.
