It's not just the husband. Schools, doctor's offices, daycares, etc. will default to calling the mother if they need to reach a parent EVEN IF YOU TELL THEM TO CALL THE FATHER. It's maddening. When you go into a furniture store or a car dealership with your husband, the salesperson will talk to the husband. My husband has explicitly said to these people sometimes 'My wife makes more than I do, she's the one making this purchase' and they will STILL talk directly to him and ignore me.
A boss I worked for recently was angry at a coworker of mine who took a few days off when his son was sick. His exact words when he admonished him later were "Doesn't your wife have sick time? Aren't sick kids her job?"
This same boss once tried to sign me up for training while I was going to be on maternity leave because 'you aren't going to be doing much anyway, babies are boring.'
When he found out I'd be closing my office door a few times a day to pump when I got back to work he threw up his hands and said that I'd be 'useless for most of the day.'
And then one time he was trying to plan for a project and straight up asked me if I was pregnant. I was shocked, but said no. And he followed that up with 'well, are you planning to be because that would be really inconvenient.'
Later in a meeting full of men when I was the only woman present and pregnant, he counted back on his fingers and then said, "I guess your husband had a lot of fun in June, huh?"
