idiotic
The "correct" time to leave the office is driven from the top down. The top guy has a word in his immediate inferior's shell-like and gets him (always "him") to pass it along. Nobody wants to work less than their boss, so this top-down culture of overwork is obviously reversed by the same top-down mentality.
I can only assume that the half million yen a month cost of this service is being sold on the strength that if employees don't react positively then the bot can be reprogrammed for spying or search and destroy missions.
