The Honest Arithmetic When Everyone In The House Works
Two full time jobs plus a household is more hours than exist, and pretending otherwise causes the fights.
When every adult in a home is working, the arithmetic is unforgiving and mostly unspoken. Paid hours, travel, and the recovery time that any demanding job requires already consume most of the waking week. The household work sits on top of that, and it does not shrink to fit. What follows is a slow accumulation of things not done, which surfaces as irritation about a specific unwashed dish rather than as the structural shortfall it actually is.
Doing the sum out loud helps more than it sounds like it would. Count the real hours: paid work, travel, and the fixed obligations nobody can move, for each person. Then look at what is left and what has to fit in it. Very often the honest conclusion is that the household is attempting more than the available hours allow, and that no redistribution between two tired people will fix it. That is a different problem from an unfair split, and it needs a different answer.
The answers are limited and worth naming plainly: do less, pay someone to do some of it if that is available to you, accept a lower standard in named areas, or change the paid hours. Most households end up with some combination, and most only get there after months of trying to solve an hours problem with a fairness solution. Deciding together which standards are being deliberately dropped is far better than each person privately deciding, because privately dropped standards look, to the other person, exactly like not bothering.
