DS developed a temperature at nursery. My DH left work to pick him up. Nursery policy means he has to be kept off for 48 hours. Fair enough. I thought it would be considerate to let work know asap that I would need to look after my DS on the second day as DH took the first day to look after him. However work claim this isn't an unforeseen illness and are insisting that I apply for dependency leave (which would be granted but possibly without pay). AIBU to take my toddler in to work...? He's not 100% but also not horribly ill.
