DD is a single mum and has 10-year-old twins. One of them is being treated with steroids for a kidney condition that has suddenly flared up. Steroids are immunosuppressant so she HAS to isolate for at least 11 weeks and DD has to stay home to look after her. Her employers - an NHS hospital (and incidentally the one that's treating the child)! - say they won't pay her salary. Is this unreasonable? Has anyone else had a similar experience?
