The article title says “university wipes out gender pay gap with salary hike”, but it looks to me like the raise is only for the female professors. For those who speak American, that’s just the full professors. It COULD be that those were the only ones paid less, but it seems unlikely given the other stats in the article. Anyway, a move in the right direction!
UPDATE: I missed the bit in the article which said there weren’t significant gaps at other pay grades.
