We need to do everything we can to ensure people can isolate and quarantine as effectively as possible while preserving their livelihoods and human rights.
Here's what I reckon:
Anyone who is told to isolate or quarantine should not have to rely on SSP or benefits, they should get 80% furlough pay for those weeks.
Employers should be made to respect isolation and quarantine as valid reasons for time off, working from home or furlough. Employers who press their workforce to continue coming in when they have symptoms, have tested positive or have been identified as a contact should be heavily fined by HSE.
It should be an automatically unfair reason to dismiss someone because they have taken a test or have isolated or quarantined on the advice of the NHS or a public health body. Negligently permitting the transmission of a pandemic virus in the workplace is a health and safety issue and if you are dismissed because you take action on a H&S issue it's automatically unfair. Which means you can take action against your employer from the first day, you don't have to wait until you've been there 2 years.
It should be made the default option for people to quarantine and/or isolate away from the rest of their household with appropriate medical monitoring and health care where necessary, and for an adequate amount of time.
We have loads of empty hotels, holiday parks, self catering holiday lets etc. and they're all on the brink of going bust. Why aren't we using that capacity for contacts who need to quarantine? The government could pay the hospitality industry to do something really useful.
We have vast empty nightingale hospitals which have turned out to be obsolete by the time they were built. Why aren't we refitting them as comfortable places to monitor and care for anyone with symptoms or who has tested positive and who can isolate away from the rest of their household?
Not everyone would be able to isolate or quarantine away from their families and that absolutely needs to be respected but there are a lot of people who could, and who would welcome the chance to not pass it on if the proper support was in place and if their human rights were respected.
All of this would cost a lot of money but it would be much cheaper than a second wave and a second lockdown.
