Work expands to fill the time available for its completion. If you’re into productivity, you’ll know this proverb as Parkinson’s Law. This interesting statement was made by Cyril Northcote Parkinson, the famous British historian and author, in 1955.
Parkinson’s Law – work expands to fill the time available for its completion – means that if you give yourself a week to complete a two hour task, then (psychologically speaking) the task will increase in complexity and become more daunting so as to fill that week.
It may not even fill the extra time with more work, but just stress and tension about having to get it done. By assigning the right amount of time to a task, we gain back more time and the task will reduce in complexity to its natural state.
Parkinson’s Law is an observation, not some voodoo magic. It works because people give tasks longer than they really need.
