Paying back in spades
Best to prevent revenge scenarios in the first place. Think ahead of the consequences of your actions and how it might be interpreted by your co-workers. In case you have no choice but hitting back, follow these steps. Plan all details before you take any action. Compile information on your target and turn information into intelligence. Be as inconspicuous as possible. Never drop hints about your plan, keep your mouth shut. If accused, deny everything.
