This always seems one of those damned if you do damned if you don't scenarios!
Much as I try not to, I'm coughing a lot and I sit quite close to other people so am likely infecting others.
At the same time it seems a bit wussy to go home just for a cold!
Luckily am department manager so can pretty much take myself off and no one will scowl at me but I know when I was junior I'd always sit there suffering hoping to be sent home.
FWIW I always tell my team to go home if the have a cold and are feeling really lousy.
WWYD?
