What you say is all true, winterwhite, but I don't see the link between pay and conditions of care workers and whether they should be vaccinated.
Yes, they should definitely be better paid and work fewer hours. Arguably, it is also true that if this happened there would be more applicants for posts, and employers would have a greater choice when it came to fitting the most suitable candidates to the roles, however, and this would screen out those who don't want to be vaccinated before they even got the job.
At the time when they weren't given enough PPE (which was, undoubtedly, dreadful) there wasn't a vaccine, so I'm not sure of the link there, either.
