Agreed, Fair. :( I'm allowed two days per annum paid leave for a sick child and it's expected that I use that time to arrange another form of childcare and back into work within the hour. I know people say teachers/school staff have too many holidays etc but when it comes to a sick child, it doesn't always happen during half term or the summer holidays. So, in other areas of work, people might be able to use their annual leave to cover most sick days to prevent losing pay whereas, I can't.
It's rubbish but you've just got to get on with it.
