Which departments need to be cut down then? Under performing individuals are indeed the first on the chopping block. Which job do you want to see go?
Shall we make all the prison officers and probation officers redundant? Oh wait, we have a massive recruitment and retention crisis across HMPPS and things are dangerous.
Passport staff? So you can wait longer for your passport? DVLA for driving licences?
DWP so it's even harder for people to get their UC adjustments made, appropriate benefits paid or advice?
Communities and Housing? Cabinet Office? FCO, HSE, MOD, Border Force, Education, Rural Affairs, Business, Transport, the Treasury?
Where, exactly, would you start? Most departments are on the bones of their arses.
For example in my dept under a recruitment freeze, internal restructure with a whole level of B9 management being made redundant and volunteers requested for redundancy across the bands and grades. They all leave in 8wks.
Most specifically covid related jobs were temporary contracts (management of the testing, modelling, analysis, etc) , so they aren't working in the CS any more. There was a big section of the CS working on post Brexit untying of bureaucracy, but most of that is also over and people moved on / moved back I to their previous roles.
