KTVU higher-up suits are ticked off that Mibach was unable to form an on-air bond with Arnold and seemed rather delighted she split --a KTVU staffer: "It wasn't his fault about 'Keba's situation but in their mind he never really tried hard to work with her."
Mibach's status would seem to be secure from here simply because another big-name leaving KTVU would be more harmful and add to the overall chaos currently afflicting the Fox2 O and O (owned and operated station)
Then again, Mibach's profile has been significantly marginalized at Jack London Square --therefore if he's indeed ultimately sacked, I'm not surprised.
Another thing: who is an adequate replacement?
We'll be watching.
