I would hazard a guess that a weak manager, manages all employees poorly. However, I would bet a lot of money that, like so many things in life, when you are bad in all quadrants on one thing, you'll likely be bad at other things like managing women. Realistically, they are the nearly the same to manage, but you can do some dumb things to make them feel excluded or make them feel like there is a boys club (probably because there is.)

Susan Fowler's team, for example, a bad manager thought it was a good idea to save costs by not purchasing leather jackets for women on the Uber DevOps team. Spare the few hundred or thousand dollars (even if it were in the thousands) and make your employees feel equal and like they are a part of the same tribe. It's common sense. Pocket change to Uber and it makes people feel comfortable around their coworkers, and they will enjoy being part of a team and being passionate about their work-unit, co-workers and take pride in their company.

Here's some anecdotal evidence. I had a product manager last week tell me she thought it was great that our company bought women's jackets for the team instead of making them wear bulky men's sizes like so many companies she has worked for in the past. That cost me less than $150 for them to set up the plates/screens/whatever with the printer but it bought me thousands to tens of thousands of dollars in good-will. Great investment. For me, this was a small gesture on my part and the companies behalf. But, it went a long way. The ladies on my teams are strong contributors, and it's table stakes for me to make sure they feel included and part of the team. Even if I have to tailor to them. Pun intended.

My direct management of every employee is a little bit different based on who they are, their communication style, how they receive feedback and their work-style. I assume that gender goes a little bit into how I interact with each person on my team and I am willing to admit I probably have some biases but overall if you're already managing your team with a high eq, you'll fare well and create an inclusive team.
