Horrible, horrible, word, even if it is tongue in cheek
I do check my email twice a day when I'm on holiday, if there's a decent signal or WiFi access - I will reply to anything pressing or forward it on to the right person. But I don't do the equivalent (for my profession) of "writing an article". I'm on holiday, the people in the office can do that.
I certainly wouldn't ever expect anyone on my team to check their email while they were on holiday. The reason I do it is to make sure I come back to a relatively empty inbox, and no nasty surprises. But I certainly wouldn't allow it to intrude in any way on my holiday time - and when I go away the week after next to the wilds of Dartmoor with no email access I am certainly not going to worry about it. And I'd be worried if one of my team was sending huge numbers of emails while on holiday (one of the other directors does this and it drives me crazy - he doesn't know what's been going on, and isn't properly engaged, so responding to his emails just acts as a distraction)
I also disagree with her point that professional people don't need designated holiday because the work and home boundary is so blurred - it's great to think that we wouldn't calculate annual holiday leave, and it's something we as a business are thinking about, but I do think it's important that people do go on holiday and take time to recharge. And I am very clear that when I am on holiday I am not going to be "working" in any sense that anyone would recognise as work (mind you, faffing around on MN right now probably isn't what my colleagues would consider "work" either)
