I run an arm/operation of an organisation with a turnover in the hundreds of millions and to think that people in different sectors work harder than others or are worth more is tabloid type fodder for gullible people.
Talented high performing people work in firms large and small, charities large and small, there are great teachers and lots of people are mixed sector. There are poor performing people in all sectors as well, we’ve all come across them. Plenty of private businesses and consultants rely on contracts from large public sector and Whitehall. I used to be one of them.
