My sister has 2 dc and one has a cough. It's clearly a cold she has a runny nose and just sounds snotty and phlegmy. She of course got her tested and it was negative twice three days apart (her partner works for a testing site and she is also a keyworker) she informed the school that she has a mild cold snotty nose and a little cough if she's running around a lot etc she told them she has tested negative the last one being just yesterday and the one before Thurs when she first got symptoms but the school have said that she can't attend school for the 10 day isolation period which means she also cannot work. She feels the school are being unreasonable as she has tested negative so doesn't understand why she can't go in as prior to this a mild cold wouldn't stop them going school?
Who is being unreasonable?
