So explicitly stating the belief that men and women are equal and should also have equal chances at promotion and holding people accountable.... If not, it has been shown to be very effective to have 360° evaluation. Having subordinates evaluate leaders, not just superiors evaluating employees, is critical.
Also important is trying to foster more cooperative work environments that do not pit employees against each other, and especially de-emphasizing sex and gender differences through desegregation both horizontally and vertically within organizations, and being careful not to symbolically reinforce gender inequality with a variety of methods. I can go into those if you're interested.
I have some other comments on problem solving, but perhaps we can get to that in the question and answer period.
Thank you.
