I hope this link comes out properly. It's a really interesting article about the nature of 'invisible illnesses' and the impact they have on people who are trying to continue to work. The author (Jason Reed) suggests the the whole organisation of work (particularly in terms of work patterns and hours) needs to be reconsidered.
I found it very refreshing to read an article that questions the way we view the working day as something that is fixed and unmoveable.
There is definitely room for new thinking
