Pros
Lots of bright, sharp people trying their best to do a good job and succeeding on the whole. Excellent benefits package. Nice new offices on the whole and a strong investment in L&D. Much stronger cost focus, but restricted by the antiquated public sector accounting approach. Once you are in you are pretty much safe.
Cons
Can be easy to be a small cog in a large machine. Very frustrating for those from the private sector. Litigation culture means everyone spends an inordinate amount of time covering their back. Turf wars between senior management prevent clear communication of vision. Very difficult to get rid of underperforming staff - and there are a few left! Often little drive to change things in some areas. Lots of turnover of staff in some areas too.
