The Personell Department
Bless 'em.
Helpful people, who made sure that all the right forms got filled in at the right times, the taxes and pension contributions got paid, holiday records were kept, sick notes were filed, and all that sort of stuff.
Then, along came Human Resources and some people found ways to turn a purely clerical necessity into a position of real power within the company: the perfect niche occupation for the manipulative nasties in life.
