I work in software support. In my current company, the rank and file are close-ish to half male/half female, but management is almost all male, including all the way up to the 4 founders/heads of the company, and most customer teams are male-dominated. I often am on calls with the network teams at customers, and it’s very common for those almost entirely male teams to ignore what I say because I’m female. I very often have to repeat myself many times, and even then it usually goes better if I bring a male on the call to say what I’ve been saying. However, I’m pretty lucky, because when I brought up that one call in particular got sexist, my male manager essentially said “That’s not ok. Should I talk to their leadership?”. I’ve never had a manager, even a female manager, respond that way. Previous managers always pretty much said to deal with it, which I’ve gotten pretty good at. Now, I will sometimes bring my male manager on calls so that when the team asks him a question, he can say I’m the expert and let me answer. It doesn’t hurt that I do have a deeper knowledge of the technical areas, and my manager knows it.
