I just spoke with someone in the company and was told that the reason they hired Emma back is because the feeling is that whoever made the call overreacted and realized that what she did was nowhere near as bad as some of the other things that have happened with some people that are still employed with the company. In 2012, WWE Diva Cameron was arrested for DUI and tried to bribe a police officer. The story at the time was that she offered the officer $10,000 to let her go.
Even worse is that when she was arrested and jailed she never let WWE know and WWE found out by reading about it online. She was not fired for what she did.
