The big difference between schools and hospitals is that in hospitals the staff are exposed to people who are sick with covid and are shedding vast quantities of the virus. They are also overworked and exhausted and emotionally and mentally drained by dealing with patients they care for in pain or dying.
One of the main reasons for those working in education quitting is stress related, over worked etc.
You think dealing with a bunch of hormonal teens is a picnic? Some will be abused at home, some have various illnesses, some it's a waiting game for those students to die. That's without the car crashes, the stabbings, the od's etc.
You think these people are robots devoid of any feeling.
Imagine working with someone young for several years, you know it's going to happen, but it's still hard when they die.
In that sense, death of patients is easier for a lot of nhs staff, especially those on wards. They don't always spend enough time with their patients for that emotional attachment to form.
One school I worked in for 4 years, 35 pupils passed away. As someone working in school, this was something I didn't expect, well not those numbers anyway. Just like NHS and carers we had to learn to desensitise ourselves. Didn't make it any easier tbh. A few of those btw might have been avoided if other parents hadn't dosed up their kids with calpol. By the time the effects of this shit wears off, the thing had already spread. But obviously, the link couldn't be proven even though we witnessed the spread. The school, transport, nhs, lea all have evidence of this from all our time off.
It's only when things run wild like chicken pox etc in communities that trigger an alert that we hear about. We don't hear a third of whatever schools were absent in November because of whatever was going around. We don't hear that a class was off because of D&V unless our kids, or someone we know goes there.
