I'm only speaking of the IT Dept MGTI based in Milton Keynes : The environment is fear based. It's very questioning and demanding of answers when things go wrong, with very little being learned from this.
A large number of workplace decisions are based on perception. Rarely do people ask questions about that perception, to make sure, there is actual fact. But, this isn't even something that's hidden... Some managers seem proud of this. Frequently in my early days I was told by my management team "perception is everything"...
There is a significant case of "old boys club" going on here. You can not be fantastic at the real meat and gravy of your role, so long as you remember two things... The rule about perception, and being on great terms with certain members of management.
