All businesses have rules; some official, some unofficial, but to work for a company is to know what is expected of the employees and that includes specific guidelines that are to be followed. The world of professional wrestling and the WWE are no different as they, too, have their own set of rules that they expect the employees to abide by.
We don't mean wrestling rules like having ten seconds to get back inside the ring, breaking a hold when the opponent touches the ropes, or getting disqualified for using a steel chair, but rules that talents should abide by if they don't want to ruffle any feathers. A few rules may even apply to the company itself, but would be good for the talents to know.
In another era, half of these rules might be thrown out the window or not apply given the nature of both the talents and the environment of professional wrestling back in the day, but in 2015, these seem to be followed much more than they're forgotten. These laws being discussed won't be found in any sort of handout or collateral a talent receives when being promoted to the main roster. No: think of these rules as tips that might be shared from a veteran worker to a respectful rookie on a car ride from one town to the next.
Some of these unofficial rules may carry a larger impact than others, but all of them help shape the world that WWE is today.
