Why McMaster University gave its female academics a pay rise

Good for McMaster. I wonder how many universities have done the analysis, found the pay gap and then done nothing? Or, more likely, set up a project to come up with recommendations etc etc that never quite delivers the outcomes? Quite a few I would have thought. However, as he points out, great for the women currently employed but the pay gap will still start again and continue if the unconscious bias of recruiters and managers responsible for pay isn't tackled. How much do you value your teaching and research staff, enough to make a few senior people feel uncomfortable?
