Furloughed workers enjoying 80% wages for no work are amongst the most vociferous dementors.
Only public sector workers on 100% pay for no, or close to no, work are louder.
There are plenty in both groups that want to go back to work, but it's a bit silly to deny the incentive to dement created by giving lazy people money for doing nothing.
I fully support the furlough scheme, BTW. I think it makes sense to prop up the economy like this now. But like everything, it carries risks and one of them is getting reluctant workers back to work for only 20% of their pay.
I think a significant element of the supposed fear of Covid is a reluctance to go back to work.
I also think that's why the schools thing is so big with dementors - having no childcare options makes it far easier to justify not going back and not getting much work done.
Which is not to say the lack of childcare and schools isn't a reasonable excuse - it is. But if you are determined to keep those options closed to you, it starts to raise questions about your true motivation.
