//Why do you seem to think that the civil service is not working?//
Let's have a look:
The DVLA:
https://www.thetimes.co.uk/article/dvla-backlog-as-medical-delays-to-drag-on-until-autumn-jhtm27xm3
“The Driver and Vehicle Licensing Agency (DVLA) has admitted that there will be no return to normal service for drivers with medical conditions before the end of September. More than 200,000 applicants have waited longer than 10 weeks to find out whether they can continue driving.”
The Passport Office:
https://www.theguardian.com/money/2022/apr/30/passport-office-delay-thousands-summer-holidays
“Travellers told to apply as soon as possible as MPs accuse agency of running ‘absolute shambles’. A couple this week told how they face having to cancel their wedding because of continued delays at the Passport Office.”
The Probate Office:
https://www.theguardian.com/money/2021/dec/30/probate-delay-is-costing-us-1000-a-month-in-interest
“My uncle died 11 months ago, and my mother also died, leaving my brother and myself to settle his estate. Ten months after applying for letters of administration, we are still waiting for probate to be granted.”
The Office of the Public Guardian:
https://www.which.co.uk/news/article/power-of-attorney-registration-delays-of-up-to-20-weeks-could-leave-families-in-legal-limbo-aFbyQ4B0DvKu
“The OPG, responsible for processing Power of Attorney applications, said in July that people would now have to wait up to 20 weeks to register the vital document.”
The Department for Work *& Pensions:
https://www.thisismoney.co.uk/money/pensions/article-10415225/State-pension-delays-Furious-pensioners-slam-DWP.html
"State pension chaos at the Department of Work and Pensions has led to one widow, 82, waiting more than a year for her money and ending up being owed £75,500, This is Money can reveal. A service meltdown has seen pensioners face phone logjams, empty promises of help by staff when they do get through, and in the worst cases hardship or hunger while trying to get payments started."
Do you want me to go on? (Other examples are readily available).
These are manifestations that the Civil Service is not working. They come from looking at the easily recognisable customer-facing services it is tasked to provide. There is no reason to believe that it is only those departments which are not working properly. There have been examples of Ministers being unable to function properly as well (for example when the Afghan crisis kicked off and all the bods in the Foreign Office were WFH with no access to sensitive documents, thus making Ministers' reactions to the crisis almost impossible).
A poster a few days ago asked "why is it that Civil Servants are always the whipping boys?" The answer is straightforward. It is because they seem to assume some forms of entitlement that no other employees have. For example, their union has recently said that their members "feel pressurised by government officials to return to their offices without outlining what benefits this will bring to the workers or their employers." The benefit to the workers is they get paid; the benefit to their employers is they get the work done that is required. Most of all - and completely overlooked in the Union's question (unsurprisingly) - the benefit to the customer (i.e. taxpayers who need these services and can get them nowhere else) is they get the services provided in a reasonable timescale and with as little trouble as possible. Clearly, from the examples I've given above, that currently isn't happening.
