Our place gives incentives each Christmas to those that have zero sickness time off. 1 year you get a voucher for X, if you do 2 years you get that doubled, beyond that you still only get the same. I havent been off sick now in 6 years (vertigo back then and simply couldnt drive nor sit still and use screens), it isn't a case of manning up etc neither, I think its just acknowledging that if you are well enough to get out of bed that day then you're good for work (in my vocation, Private sector IT). Obviously for some jobs feeling a little fuzzy the odd time is not good enough though.
Some of our other offices see guys in IT taking days off regularly, sometimes it can even be the office culture, I know some civil servants who count two weeks of illness as part of their holiday hours! :O
