At the end of the day he is in a top job, very well paid with lots of responsibility.
Rightly or wrongly in those jobs how you conduct yourself outside of the working sphere plays a massive part. Yelling obscenities about people from a certain part of the country and behaving in a completely out of control way is hardly going to fit with the type of image his company wants to portray. Nor are his hateful blogs.
His problems for employment are going to be exacerbated by his position and nature of his job. His position means he is likely to have a team of people working for him who are expected to live up to a decent standard of behaviour in public. I would imagine his ability to conduct that part of his role is greatly undermined.
Secondly his role as a lawyer is about calmly accessing information and making a case. He is completely out of control in that video, he's lost it. I imagine his employers have seen the writing on the wall.
No doubt there will be some saying "nanny state" this or "what's wrong with a bloke letting off steam". The obvious point to make though, is the sort of bloke who wants to engage in such banter doesn't get the opportunity to work in such jobs. They kind of root out that behaviour. Likewise it can't really be a nanny state when it's a private company, often hostile to the states aims who have made the decision.
There will be a dozen people better suited ready to fill his role. I am not saying that's right or wrong, but this isn't your knobhead 17 year old who works for Macdonalds, this is a highly qualified individual.
I have to say I don't particularly like the idea that people are expected to carry on a level of professionalism outside of the workplace. Nor do I think people should really be losing their jobs for stupid behaviour outside of work.
However I can't imagine that idiot would hold any great degree of sympathy on either of the above issues. I'm sure he'd have people sacked if he wanted too, he just wants the right to do it himself. That alongside the fact he basically runs a blog attacking poor people and hates people from areas of the country that are less affluent doesn't endear me to him greatly and I can't care much either way.
But please, drop this bizarre notion that this is indicative of some loony left regime of political correctness. A knob acted in a deplorable way. His right wing, anti-state, anti- PC private company subsequently decided he was a liability to them. If you have any anger direct it towards them. It has nothing to do with the state, who have made no attempt to infringe his right to free speech. A right to work in a how profile job is a very different thing.
