Two of the more obscure of human occupations is the Manager and the Supervisor, whose job it is to interrupt the other workers from completing their tasks by assigning new ones, tasks the workers were about to undertake anyway, and then informing them later of all they have failed to complete. The Supervisor is especially puzzling in that they seem to duplicate the role of the Manager and they don’t even wear visors, or seldom do. Possibly they did in the past and the name is a holdover.
Due to the illogical nature of these roles, one can only assume they sprang from an as yet undiscovered religious observance, possibly a lesson in humility. The result is more often humiliation.
