I kind of like Dr. Peteron's view on these kind of questions, try flipping them around. Don't ask "Why do women earn less?" Try framing it as "What are the reasons men earn more?" Another one, "Why is it that there are so few women in high level management positions?" frame it as "Why are there so much men willing to put up with the stress and pressure of high level management positions?"
There are a lot of reasons for the inequality between men and women. I'm not saying they are "justified" or "fair" but there are some obvious (painful, even) but true reasons why men and women don't earn the same. Of course, these reasons do not specify the whole margin but they explain quite some of the variation.

What does it change if the answer is "It is easier for men because they have to put up with less harassment, less pressure and are more encouraged"?

Except this "framing" implicitly introduces the assumption that gendered differences in stress and pressure tolerance is the cause.
Income inequality?
Does risk of dying on the job count as something worth higher pay?
If so, then I think you should reconsider the mantra of "wage gap".
Note: this is just the first hit on google, I'm a bit reluctant to write down an entire arguement here because you have very like already made up your mind...
But you are describing "sexist outcomes" which isn't the same sense of the word. It alludes to a sexist mechanism only - whereas the board quotas are the sexist mechanism.
"Income inequality" Has been discussed plenty of time, so I'm not going to reproduce it here. In any case, there is plenty of dispute on whether it is the result of "sexism".
"domestic workload" is something society does criticise, but in any case it is a social convention only - not enforced by law.
