My work operates the Bradford scale, I'm a single mum and have very limited help and my child minder has norovirus. At the earliest my child minder will be available Thursday but I don't know how long it lasts normally.
It seems unfair because I have to be off when childminder is ill when I'm ill and when little one is ill (touch wood me and 2 year old don't get ill very often but still)
If you have a partner then they can share the sickness with you but on your own you have 3x sickness to account for.
My mum has got LO today and can have her Thursday but I have no one for Tuesday Wednesday Friday (if child minder not better).
On the Bradford scale it's worse for me to have Tuesday Wednesday and Friday off than it is to have Tuesday Wednesday Thursday and Friday which means I would have to lose 4 days pay not 3.
AIBU to say it's unfair on single mum's and they should give you leeway depending on circumstances.
