I had one fantastic, sensible boss who would send you home if you felt bad with a stern "We don't want your germs, come back when you're better". Some bosses are able to see the bigger picture = one employee off for a bit, instead of all employees off one after the other making far more impact on the service.
No-one else I've worked for since has had that attitude though. It is seen as being a fab person all round to struggle in unwell. I went in recently with an awful throat infection, and almost no voice and no-one even mentioned the fact I was having to gasp to talk to them, let alone felt I ought to go home!
Only went in BTW as have had time off sick for another matter and as manky says with her DH, I had been 'made aware' my sick leave was 'rather high'.....
It's so short sighted. Of course alot of bugs are passed before people even know they're ill which is just life, BUT I'd rather people went home than coughed all over me, and left bugs all over computer keybaords, door handles, the kettle......
