The work doesn't have a fixed duration; it stretches to fill whatever container you give it. Parkinson observed this originally in bureaucracies (a report that could be done in one day takes three when three are allocated), but the pattern is universal in knowledge work. ## Why it happens **Effort adjusts to perceived time available.** If you have a week, you approach a problem as a week-long problem. If you have a day, you find the 80% solution that matters. **Scope expands with available time.** Extra time rarely stays empty — people find adjacent improvements, additional polish, more edge cases to handle, more documentation to write. This isn't laziness; it's often genuine value-adding activity. But the result is that the task always ends up using the time. **Perfectionism is proportional to deadline pressure.** "Good enough" requires a definition of "good." When there's abundant time, "good enough" ratchets upward. **Meetings expand too.** A meeting scheduled for an hour takes an hour. The same discussion, if you must resolve it in 30 minutes, usually resolves in 30 minutes. ## How to use this for good **Set tighter deadlines intentionally.** When you want a decision made, a d
