Think of fairness as matching capacity, not forcing a daily 50-50. Do a one-time sit down to list every recurring task and estimate minutes per week for each. Use your work hours to set proportional weekly targets. For example, if you work 40 hours and your partner averages 55, you might aim for roughly 60 percent of the total chore minutes and they do 40. Put the targets and task owners on a whiteboard or shared note so it is visible and not living in one person's head.
Create two modes. Normal mode when hours are typical, and heavy week mode when they have 10-12 hour shifts. In heavy mode your partner only covers must-do personal stuff like their laundry and a quick tidy, and you absorb the rest, then you rebalance on their days off with a couple of longer tasks they prefer. Keep a few fixed owners to reduce mental load, like one person owns bills and litter boxes, and rotate the "manager" for groceries and appointments each month so the planning burden is shared. Set a minimum standard so you both know what "good enough" looks like, and agree that deep cleaning stacks to weekends. Do a 15 minute check-in each week to answer three things: what's heavy for each of you, what can slide, and what help is needed. When schedules change day to day, use a quick text rule like whoever is home first starts dinner and dishes, and the other closes the kitchen for 10 minutes before bed.
