Parkinson's Law was never really about deadlines
The line everyone quotes — work expands to fill the time available — was the setup. The real joke was a formula.
In November 1955, a historian named C. Northcote Parkinson published a satirical essay in The Economist about the British Civil Service. Everyone remembers the aphorism it produced. Almost no one remembers what he actually proved with it.
Parkinson pulled the Admiralty's own staffing records. Between 1914 and 1928, the number of Royal Navy ships in commission fell by roughly two-thirds and dockyard workers dropped by a third — while the number of officials administering the fleet rose by nearly 80%. He found the same pattern at the Colonial Office: staff kept climbing at 5 to 6% a year through the 1930s, 40s, and 50s, entirely disconnected from whether the empire it managed was growing or shrinking to almost nothing.
His explanation had two working parts. An official wants to hire subordinates, never rivals — subordinates make him look essential and never threaten his job. And once hired, those subordinates generate memos, drafts, and meetings for each other to answer, which then justifies hiring more people to handle the correspondence. The empire grows on its own exhaust.
The modern version isn't a government department. It's the meeting invented to discuss the last meeting's action items.
