I agree with TT, god that hurt!
In my opinion, JH would be the first to admit he's got quite a job ahead of him, the damage has been done, primarily by AF, then exacerbated by KM.
JH can (attempt to) fix it and ultimately get sacked (or moved down/sideways) because it won't be in line with the Master; or he can do what the Master wants and he'll be sacked (or moved sideways) cause it will get worse. Third option is do a little of both and the staff will want to lynch him and the if the Master finds out then it'll still read as above.
Great job to inherit, NOT! Good luck JH, you'll need it. I hope you can do something positive; the EBA will make or break all that you do; small steps in the right direction will be destroyed by something silly.
Arrrr
