The point is that there is no other alternative. My observation, at least in tech - is that the expectation of greater than 40 hours of work per week is ever present. There is no choice to earn less, take it easy, and have more time for other pursuits. If both parents are under this expectation then there are fewer hours to be involved. A break of 1-2 years will be held against you in future interviews.
From talking with other parents, this is a common conundrum across industries. No one feels that they have enough time to be a good parent.
More concretely, what work arrangements do you have or are aware of which allow you to cap the hours worked while affording a livable home life?
There is no choice to go to your boss and say “hey I want to work 20 hours, can you cut my salary in half and keep my benefits”?
This misunderstands your value as an employee (linear function of time at the office) and signals you aren’t really interested in the project.
However there absolutely are companies, and roles within the company, where you can work much less than 40 hours - you just can’t explicitly ask for it.
> A break of 1-2 years
Yeah another example that won’t work.
