The old chestnut about the Public Sector being lower paid is a myth. It may have been the case 20 years ago, but it's not the case any more. Not many shop workers, security guards, delivery drivers, or farm workers in the public sector.
Much better pensions in the Public Sector too.
As a matter of interest, how many Public Sector workers have been either been furloughed or lost their jobs in the past year?
220 staff work(ed) in my local authority. At first lockdown, around 70% were fully furloughed (in my department - only five of us out of 50 were not furloughed) - most for the duration. We have now restructured because of the financial hit, and we have lost 15 of our 50 (plus others in other areas). Out of the 35 that are left, around 15 are still part furloughed at the moment (working half-time).
