#2 Could hurt the WWE : CM Punk rubs many superstars the wrong way.
No matter how talented you are, not being able to get along with your co-workers is a huge problem.
Human beings are social creatures, and naturally interact with one another. In the wrestling business, where the health and safety of your colleagues is of the utmost importance, it becomes particularly profound.
There's a list as long as your arm of pro wrestlers CM Punk has upset over the course of his career. He once had a heated argument with The Undertaker.
Not to mention his long standing grudge against WWE upper management. Hiring CM Punk back to the WWE may cause a lot of chaos back stage and might not be the right move for the WWE.
