As I understand the situation, Mr H has his disciplinary with the company later this week, for whatever he has been accused of.
A cynic might just suggest that his latest set of unproven allegations are the last throw of the dice from someone who just wants to queer the pitch / stir up as much unrest as possible before he is managed out of the business.
I would put it at no better than evens that he will be a BA employee when this is done and dusted, and frankly the company will be all the better for his type being let go.
If it happens though, what is the bet the McClunky will find him a nice little earner at Unite.
