Here's the money quote:
But take a closer look, and it turns out the male directors had an average
of 14.8 years of news work experience, while female directors had only 5.6
years. In other words, the men had almost three times more work experience, but
were paid only about a quarter more.
I've been telling people the same thing for years... decades, even! Men have more experience, and generally are able to work longer hours. My parents both worked, but if I was sick and needed to be picked up from school, it was my mom who got me more often than not. My mom worked regular hours; my dad worked nights and weekends and was on call. It's all about the division of labor. I'm not saying women are required to do this, I'm just saying that in general, that's how couples tend to split the responsibilities, even if the Lileks household doesn't.
It's the same in my house -- I am usually the one who takes our son to daycare, and usually the one who makes dinner, for example. My husband does both, too, but the majority of the time it's me. I never work nights or weekends. He frequently does. It's just how the labor is split.
