Except it very rarely happens with football managers.
It does happen in the case of some kind of investigation (Dave Jones) and there's a similar thing when managers get sacked they will continue to be paid compensation but that stops if they get another job which is why you often see managers taking a break after a sacking. But gardening leave as you get with chief execs is not a thing in football.
The other factor to consider is if we appoint another manager while RK is on gardening leave that could be interpreted as constructive dismissal/breach of contract as there is no good, objective reason for RK to be on gardening leave (ie he isn't ill/depressed/under investigation for historic abuse).
Really can't see it.
