I'm a woman and fairly aggressive and experienced negotiator. When I negotiate for myself, I find the gap is about 10%. When I used to work as an agent and I was negotiating on the behalf of others, it was the exact opposite. I was able to get my clients about 10% more with less work even though I was less skilled at negotiation than other agents. If I was better, I'm curious if I could've gotten 15% or 20%. In tech though, I end up making more money than my male co-workers because engineers in general are such terrible negotiators. It's very hard to find female engineers at all, but many years ago (before Glassdoor) I did manage to interview at one company (~200 employees) with 25% female engineers. Their offer was 40-60% of market value and their benefits were awful. My guess is that the men at that company were making 60%, and women 50%. I interviewed at another company where there were 100 women employees. The only men were the 3 founders, all 10 warehouse workers, and all 4 on the tech team. Interviewed with the founder and I got an offer. It was low but I could not get him to budge a dime so I turned him down. He called over 6 times after that trying to get me to take the job. He seemed genuinely confused about why I wouldn't take it. I'm pretty sure he was a very nice and reasonable boss with the one exception of pay. He was just delusional in that department. I interviewed at a ton of these companies almost none of them are thinking "Haha! We can get away with paying our workers 70% of market value," instead they are truly deluded. I think women are more likely to just accept the low pay and not negotiate at all. When interviewing, I used to just get this intuitive feeling like "I don't think this place pays well," and it took me many years to realize what I was just seeing was too many female employees.
