It’s the law: Parkinson’s Law

By | October 23, 2018

Some people love to spout a law, rule or formula to validate their opinion or explain a situation. Problem is, I can’t remember which law is which or the difference between various rules.

So, for the next few weeks, we will post a brief explanation of the most common ones. This week is …

Parkinson’s Law

In November 1955, Cyril Northcote Parkinson wrote a humorous essay in The Economist commenting on the growth of administrative staff in the British Civil Service. He presented this as a law, named after himself, supporting it with staff figures from the Royal Navy.

The premise of his pseudo-scientific law was that the amount of work someone has expands to fill the time you have available to complete it. He gives an example of an old lady who takes a whole day to write a postcard, whereas a busy person might take only 3 minutes. Work, he says, “is thus elastic in its demands on time.”

He goes on to use this to explain the increase in administrative staff, explaining that Civil Servants hire subordinates to delegate work to, which causes an increase in administrative overhead passing it from one person to another which fills everybody’s time. The amount of work previously done by one person now takes three people to complete it.

All this is used to explain the yearly bureaucratic swelling by 5-7%, regardless of the amount of work being done.

Apparently Parkinson based his law on the ‘ideal gas law’ which says that gas expands to fit the volume allotted.

Parkinson appeared on Radio 4’s Desert Island Discs in 1979.
