I have a confession. A few years ago I came to work when I was ill. Not desperately ill – but clammy-stay-in-bed-didn’t-want-to-ride-my-bike ill. Ill enough to stay away from work. But I was really busy and had loads to do. Working from home wasn’t really an option back then – you know, in the days when meetings were mainly face-to-face. Sure, you could dial in. But people often forgot you were there and couldn’t really hear you properly when you said something. So, I came to work. It was just before Christmas. And my gift to my office-sharer was a really nasty respiratory virus for Christmas.
