Pros – good if you like going to meetings, team building exercises, over complicating statistics, rail travel to London.
Cons – over staffed and large amount of work is created by internal processes and meetings rather than the public good. 7 year pay freeze, London centred, very left leaning, and cringe worthy amounts of virtue signalling. Good also if you want to continue your academic career your colleagues can pick up after you whilst you do your own thing. Public Health England is 1/3 genuinely caring people who wish to make a change, 1/3 woolly liberals who like meetings and would be unemployed otherwise, 1/3 career types who no longer use the English language in the same context as ordinary people understand it.
