Absolutely
I long since learned - struggle into work with a cold, it'll take a week at least to disappear. Take a couple of days off - sorted.

I fucking hate people that labour under the delusion that the office will fall apart if they don't go in 'just because they have a cold'. Because, like, they're so important and shit? My boss 'struggled' in with flu a few months back. Result - one totally decimated section for about four weeks as everyone succumbed to the lurgy one by one, putting the whole programme back by about double that length.
