What if the reason you get to have a nice vacation at a particular time of year is that you are able to join important meetings from wherever?
I don't see the word vacation anywhere in the article.
Yes, vacation (or even non-working hours) would be implied in this case? Sunrise to sunset.... is that what we really want? Sure we want to be connected, but not necessarily "working".
I think they're saying that people work when they want to work. Not imploring people to work on their vacations.
The title says "infographic", and the word "vacation" IS in the infographic. Specifically, it states "47% have worked when they were on vacation". Under the image with a colspan of 2. ;)
