"The Bully has a Jekyll and Hyde nature - is vile, vicious and vindictive in private, but innocent and charming in front of witnesses; no-one can (or wants to) believe this individual has a vindictive nature - only the current target of the serial bully's aggression sees both sides; whilst the Jekyll side is described as "charming" and convincing enough to deceive personnel, management and a tribunal, the Hyde side is frequently described as "evil"; Hyde is the real person, Jekyll is an act."
