A truly astonishing type of labor action, wherein workers, in protest, maliciously follow the rules which the management et. al. insist that they follow. To the letter. And then some. It's astounding that such an action could possibly be construed as a way of bringing pressure on the bureaucracy, but strange as it may seem, most companies/countries do not structure their rules in a manner conducive to success, if they were actually followed. If it weren't for workers who are wiser than their bosses constantly breaking the rules so they worked, everything would grind to halt. And that's just what happens during work to rule.
It's truly scary that such a thing actually works.
