Uneven household chores usually mean the system is hiding part of the work, not that the work does not exist.
Make invisible work visible
Start by naming the recurring work that keeps happening quietly: dishes, resets, trash, laundry flow, and room cleanup.
Check whether tasks have owners
Chores drift when they are shared in theory but unowned in practice.
Use a system that can be reviewed
If you cannot see overdue chores, recurring tasks, and who completed them, the same uneven pattern will keep returning.
