I work as a contractor - mainly to government and my experience is that at least 50% of people in the public sector are there purely to keep people in employment. They serve no useful purpose, and mainly create made up work for each other.
I also do very little that is useful despite bringing a great deal of skill. If they cared to ask me what I think, I would be happy to explain why all the things they get me to do are a waste of time. I’d also be more than happy to suggest some simple things they could do that would actually be useful.
