You ARE entitled to parental leave if your
LO is sick! Its a bummer that you don't get paid for it but they still have to let you go when you need to.
George was very ill with gastroenteritis last week and the week before so I had to take some days off. I'm fortunate that my work are really great for letting me get off if I need to. I think you are entitled to something like 16 weeks unpaid leave a year, its either called career/parental leave.
Here I googled and found this, shove it in your managers face!!!
