On the subject of work emails, a lot my clients work in industries that are working every day (transport, logistics and other 24/7 operations) and as such I get emails all weekend from them. When I log on Monday morning after the weekend I'm always faced with a deluge of requests/queries/demands. *sigh*
I agree with you about emails, I hate people sending them to me late in the day and usually I don't respond after 5-ish but had no choice last night Still, had no calls from work today so I guess the place didn't burn down without me.
