"I did this parallel to my sprint work as if nothing had changed. This meant some of my work was done outside my normal working hours, but growth always comes with sacrifice."

The thing is, companies can choose not to incentivize this behavior, because they know how toxic it can be. I work for one that's like that. At an individual level, you do have the choice to nudge your company's culture by what you choose to do for the money they pay you. It can be a tough choice to walk away from extra $$$ you can get by leveraging your privilege that you either don't have outside responsibilities or you have someone else whose time can be converted to your career as they deal with your share of the household labor, but the only way we can fix systemic bias is with our own individual choices.
