#3 Ryan Callahan
Ryan Callahan was the lead "home" writer for Monday Night RAW. He worked for WWE for a few years but in May 2019, Vince McMahon fired him. However, he didn't lose his job because of a rating drop but rather for being someone who "was difficult to work with".
As reported by Fightful.com, Callahan had some issues with another lead writer of RAW, David Kapoor, whom we also know as Ranjin Singh (The Great Khali's manager).
Reportedly, Callahan was taking creative changes "too personally" and it didn't set a great example for fellow writers in WWE. When the issue was brought up to Vince McMahon, he immediately fired Callahan from WWE.
#2 & #1 Steve Oppenheim and Steve Guerreri
The reason we have aligned Steve Oppenheim and Steve Guerreri together is that they were fired at the same time. Oppenheim worked as an in-office lead writer for RAW and was working for WWE since 2011. On the other hand, Guerreri was the co-lead writer for SmackDown since 2012.
Both were fired sometime after WWE had hired Paul Heyman and Eric Bischoff as RAW and SmackDown's Executive Directors respectively, but they had nothing to do with these releases. WWE has been losing ratings for a while now, and according to reports, Vince McMahon decided to fire these two writers in order to "shake things up" in WWE.
