Throwing my own conspiracy in, but bear with. Given that we don't have an assistant manager, I don't think it is beyond possibility that dismissal was shaped towards the role being 'dissolved'. It's a pretty interesting loop hole that I think Grendel mentioned previously, but I have seen it being used in an old job where one of the manager's had got lazy and wasn't performing.
They knew it was a really difficult task to get rid of her, as the team were doing well (regardless of her lack of stewardship). She had been there ten years and actually built the team up herself originally. In the end they said they were going to just operate the department with team leaders, and her 'manager role' was no longer needed. They paid her off for 11months salary, which was more than enough to stop her trying to fight it.
If it was gross misconduct, surely it would just be that? There doesn't even seem to be a case of 'suspended under investigation' and the lack of assistant manager is a pretty big thing. It isn't impossible that Viveash has done something shocking, but with some of the rumours around coaching style, and dissent towards new staff, it wouldn't completely surprise me if they have just used this loop hole to get rid of him for being unagreeable or a bit tough on players.
@Saddlebrains - apologies if it wasn't you, but wasn't there something about Sheaf saying 'it's him or me'?
As Viveash in the public eye, reputation counts for a lot. Hence the solicitor involvement and lack of real word from the club.
