You know you're in trouble when a Rocket Shark start messing with your faxes. Rocket Sharks do have a tendency to mess with people to get an excuse to kill them, Rocket Sharks do have a personal set of values.
A Rocket Shark is Stealing/Destroying My Work!Edit
What should you do? I'll tell you what. Do nothing. Keep multiple copies of all of your work hidden in separate place, but with some copies in plain sight. Keeping all copies in hiding may make the Rocket Shark frusturated when tearing up specific documents in your workplace.
Remember the basic laws of dealing with Rocket Sharks:
Do not anger them.
Do not look at them.
Do not conspire against them.
