Dish Duty Rotation Commission Publishes Mathematically Fair Washing Schedule

MADISON, Wis. — The Post-Feast Sanitation Authority has published its annual dish duty rotation schedule, a mathematically optimized assignment the Authority claims distributes washing, drying, and “mystery Tupperware identification” with perfect fairness.

The Authority, founded in 2016 after what its charter calls “the Great Dish Standoff” — an incident in which 14 family members simultaneously claimed to have “done the dishes last year” — uses an algorithm factoring in age, cooking contribution, arrival time, and “historical dish avoidance patterns.”

“The algorithm doesn’t forget,” said Authority Director Lisa Grant, 54, a data analyst who now applies statistical modeling to holiday cleanup. “It knows that Uncle Ray has ‘supervised’ for six consecutive years. It knows that Cousin Jenna’s ‘bad back’ miraculously recovers for dessert. The algorithm sees all.”

This year’s schedule assigns washing in 20-minute rotations, with drying handled by a separate crew “to prevent the wash-dry monopoly,” and introduces a new role: the Tupperware Archivist, responsible for matching lids to containers, “a task the Authority classifies as both essential and psychologically hazardous.”

“The Archivist position is the hardest job at Thanksgiving,” Grant said. “You open a cabinet and face 40 lids and 30 bottoms, none of which correspond. It is a puzzle designed by a chaotic universe. We rotate the role every 15 minutes for mental health reasons.”

The schedule includes exemptions, strictly limited: the cook is exempt from washing (“they made the meal — the meal is the contribution”), guests over 80 are exempt from all duties (“they have earned rest, and frankly, they will break something”), and children under 10 are assigned “drying the unbreakable items,” a category the Authority defines as “plastic, and only plastic, and we check.”

Particularly innovative is the “dish credit” system, in which guests earn credits for pre-meal contributions (chopping, setting the table, entertaining toddlers) redeemable against dish duty. “One hour of toddler entertainment equals 30 minutes of dish exemption,” Grant explained. “The exchange rate was set by economists. Toddler entertainment is genuinely grueling.”

The Authority will station “compliance observers” — really just grandmothers with excellent vision — at sinks nationwide. “The grandmothers report to us,” Grant said. “They always have. We just finally gave them a title.”

The dish credit exchange rate is reviewed annually by what Grant called “a panel of economists and grandmothers.” Last year’s adjustment raised the toddler-entertainment rate from 20 to 30 minutes of exemption per hour, “after new data showed toddlers have gotten faster.” The grandmothers on the panel reportedly pushed for 45 minutes. “The economists said 30. The grandmothers said try entertaining a toddler for an hour and then talk to us about economics.” The compromise: 30 minutes, plus what the official schedule calls “the grandmother’s discretionary bonus.”
