Tell them that you request not to work with any suspected Swine flu cases -or anything else communicable- until your formal warning period is up, as it would technically be endangering your job. Plus say that you just want to check that if you then need to work while spreading swine flu to the potentially vulnerable and possibly immune suppressed people you deal with that you can have it in writing that the LAS would be liable for any private prosecutions, not yourself. It just makes you wonder, doesn't it, how many other public sector employees such as teachers and nurses etc will also have to go to work and spread swine flu around because they are on similar warnings. (And yes, it would possibly be possible to work despite the swine flu. I had it two weeks ago and didn't feel good, and was doped up on paracetamol, but could still have gone to work if a job was at stake. Of course anyone who caught it off me might not be so lucky in only having mild symptoms... )
