Pros
If your based in the office, your not just allowed flexibility but its a nice place to be. Colleagues are friendly and supportive, its a really diverse business so there is lots of variety. Importantly for most of us, we like the public sector ethos of improving outcomes for children and working for a company that is not driven by profits (and we have great terms and conditions!)
Cons
We don't make profits so resource is always scarce so you do have to work hard.
