Really? Mine will. My DHs will. My Dad is an employer and he would. My DBs employers were when his colleague had to. I think lots of employers will be sympathetic. As I said earlier, maybe not if you’ve gone abroad, but if you’ve come into contact t whilst going about your daily business then I think lots of employers will be understanding and some people will WFH during that time. That’s why people need to ask their employers what the situation will be if the need arises and plan from there.
Well, good for you, but I think you need to realise you're extremely lucky.
Someone on a zero hours contract who has to self-isolate will lose pay for two weeks and could just get their hours taken off them. Lots of industries are making people redundant left, right and centre and too many absences will lose people their jobs, even though it's through "mandatory self isolation".
And lots of people work jobs that aren't possible to be done from work - retail, hospitality, animal care, childcare, carers, anyone working for the NHS, transport workers to name a few - most of those jobs are notoriously low paid and have poor conditions as it is. And are easily replaced. If you work for ASDA and lose your job, there'll be hundreds lining up to take your place.
Even if employers are understanding, many of people can't afford to live off SSP - it's less than £100 a week. How can someone on minimum wage, with no savings, afford that kind of drop in income once, let alone regularly for the foreseeable future?
