I found it super entertaining.
When I left Google in 2015 to go on sabbatical, I distributed 20 copies to various middle and upper-middle managers, mostly as friendly/jocular warning/admonishing.
When I returned in 2016, it seemed that one half had gotten the joke, and the other half had used it as a manual.
Either way: The linked article shows that the author has red-discovered Parkinson’s Law for himself.
(I recommend y’all read the book)
