What does Godhart’s law mean?

It goes “When a measure becomes a target, it ceases to be a good measure.” How does that work in practice?

Another example is the bradford score. Supposed to show the effect on the company of an employees absence.

Instances X Instances X Days

So 2 days off in 2 instances = 2 X 2 X 2 =8

vs

taking the whole week off 5 days in 1 instance = 1 X 1 X 5 = 5

If I’m not sure if I’m entirely well again after taking monday off and might well be off again friday its less punishment to take the whole week off due to the lower score.

Yet the employer loses 5 days work, not 2.

Which works against the principle, especially as I won’t be telling them on the monday, I’ll be ringing in every day (in the UK we self certify up to 1 week, no doctors notes needed).
