Having worked with Sussex Police before I would never work with them again.
I had a similar role to the one advertised and there remains a level of bullying and the 'old boy network' mentality amongst the senior uniformed staff which is heavily white washed and swept under the enormous rug they stand on. Whilst it will always be denied, it still exists with plenty of information sharing down the pub afterwards to 3rd parties.
If your an activist with the Union it's even worse and if you have differing personal views to those they deem as being potentially damaging to their 'good reputation', forget it, don't bother applying.
Not all uniformed or civilian staff are like this, I did meet some really nice ones but the old regimes remain and it can be hard to stomach if you ask too many questions.
However, if your a sheep and don't mind all that, go for it.
You get to say you work with the Police.
