One of the staff who worked with him, and was one of the victims of his incessant bullying, said that " It was the one and only genuinely horrible, undermining and consistently upsetting period of my career which had led to stress, anxiety and a loss of confidence, was when I worked for him". She said Mr Bercow had failed to show remorse and had instead "blamed the process for being flawed, amateurish and unjust and not even applicable to him".
No one should be expected to work with someone who loudly and continually criticises their upbringing, education or background but I expect the usual snippy, snarky, Bercow admiring apologists will find some way to defend him his behaviour.
