Bollocks to that. When I had a partner, I always saw it as WHOEVER was the SAHP (we chopped and changed a lot, redundancies, someone gaining higher paid work that the other etc.), their job was childcare.
The other persons job was their paid work.
Essentially, we worked for the same amount of hours.
Each of us had a job, that took the same amount of hours. Outside those times, the hours we worked for, everything should be split equally.
Admin split 50-50. Housework split 50-50. And childcare outside the WOHP work hours, split 50-50. The only time that wasn't the case is when a DC was still BF. in which case, I took more of the childcare, and expected my partner to take on more of the housework, so it still all got done.
My Ex partner was unhappy with my views on this. He came from a very 'traditional' family, SAHM doing everything and being a martyr, WOHD doing just his paid work hours and NOTHING else.
I come from a line of people who have split things equally for 3 generations - even my grandparents did this, as in both cases, my Nans earnt more than my Granddads.
Didn't make for a successful partnership...
He's now my Ex. Because he expected to go out to work and do nothing else, yet when he was the SAHP, he expected to do childcare and nothing else. And I mean nothing, not even splitting the chores, he expected me to do it all after my work day.
He just basically didn't want to have to do housework whether he was WOH OR SAH. He didn't see it as 'Men's work'.
