Wow. So the answer is 'fuck them!' Great, you're all wonderful.
Imagine if you will, that a burglar is smashing their way through your front door with an axe (a job I had to resource last week). You call 999, petrified. The officers take 10 minutes to get there as the nearest unit is 15 miles way. Now the burglar has got into your house and is attacking your husband. But yay ! The police are there and arrest the man.
Now imagine that the officers that normally cover your area are all off isolating with Covid and working from home, although they just have a bit of a cold and feel fine to work. So now the response time is going to be 40 minutes because you live in a rural area, the nearest unit is 30 miles away but they have to finish at the previous emergency before they get to you. Also the control room of your local force is very short staffed due to isolating and your 999 call was answered by a call handler in another force who didn't know where you live and originally sent the incident to the wrong force. So there's already been a delay.
By the time the officers eventually get to you, your husband has a broken jaw, the burglar has got away with half your jewellery and £2k you had taken out for Christmas.
Yes this is an extreme example but this is what staff shortages on the emergency services mean. We cannot afford to lose whole sections of officers and front line staff to isolating all the time.
This morning we had officers with a man who had had very likely had a stroke. Their cat 2 response ETA, usually 18 minutes, was 5 hrs. We had to move heaven and earth to actually get an ambulance to him because they are so short staffed.
If Tesco's or schools are short staffed it doesn't really matter. For us it's literally a matter of life and death.
