Speaking at a conference, he was asked to give his thoughts about what women should do if they are not comfortable asking for a raise.
Nadella answered: "It's not really about asking for the raise but knowing and having faith that the system will actually give you the right raises as you go along."
"And that, I think, might be one of the additional super powers that, quite frankly, women who don't ask for a raise have. Because that's good karma. It'll come back, because somebody is going to know that is the kind of person that I want to trust," he added.
Nadella later apologized, saying: "I believe men and women should get equal pay for equal work. ... if you think you deserve a raise, you should just ask."
