I have a very nasty cold. Not flu, but definitely more than a head cold. I don't want to get out of bed. However I've dragged myself to work each day, been useless and slow and made myself more ill, purely as my manager has said I'm not ill enough to be off.
I have a fever, constant headache, achey bones, feel dizzy, deep, chesty cough, have thrown up from coughing... But I'm still well enough to work apparently. 
I work round kids and babies, and in a food and drink setting. One of my colleagues now has exactly the same symptoms. (Also struggling through the day.)
But if my kids had this illness, I wouldn't dream of sending them in in case they infected the other kids.
So why- when I work around kids- is this any different?
Why is it acceptable for me to be ill at work and infectious, and be praised for coming in, when I'd be a shoddy parent for sending my kids in in this state?
AIBU to think this?
