Cyril Northcote Parkinson said it in 1955. Work expands to fill the time available for its completion.
Seventy years later, we still don’t believe him.
Give a task two hours, it takes two hours. Give it two days, it takes two days. Not because the work is harder. Because we let it breathe until it suffocates everything else.
A Formula One pit crew changes four tires in under two seconds. Not because they have better hands. Because the time is fixed. Non-negotiable. Sacred. Every tenth of a second has a name, an owner, and a consequence. Nothing is vague. Nothing expands.
The rest of us treat time like a waiting room.
And then, to feel productive inside all that inflated time, we multitask.
Here’s the problem. Multitasking isn’t a skill. It’s a story we tell ourselves to feel busy. What neuroscientists actually call it is task-switching. Every shift in focus pays a cognitive toll. Stanford research found that heavy multitaskers are worse at filtering irrelevant information, worse at memory recall, and worse at managing attention than people who simply finish one thing first.
We multitask to feel efficient. We become less so.
The F1 pit crew doesn’t multitask. Each person has one job. One precise, rehearsed, uninterrupted job. That’s not coincidence. That’s the whole design.
Parkinson’s Law fills time from the top. Multitasking fragments whatever is left. Together, they make busyness feel like achievement.
The deadline isn’t the enemy. The absence of one is.
What would your work look like if you gave it half the time?
