Parkinson’s Law

“work expands so as to fill the time available for its completion”

(*) C.N. Parkinson, in “Parkinson’s Law: The Pursuit of Progress”

Stock–Sanford corollary to Parkinson’s law:

“if you wait until the last minute, it only takes a minute to do”

‘s corollary to Parkinson’s law:

“work contracts to fit in the time we give it”



“the demand upon a resource tends to expand to match the supply of the resource.”
“(the reverse is not true)”

Some define the law in regard to time as:

“the amount of time that one has to perform a task is the amount of time it will take to complete the task”
