My rule of thumb is travel time = work time, so i rarely travel on Sundays and late friday nights. easy to justify when i do reports and admin work on sat AM or all evening/late with news/ball game in the background.

therefore, when i take actual vacations, my vacation begins the last workday, usually around 6-7pm that evening, and I'm not plugged back in until that first actual workday (normal start time for me is usually around 8:30...but some days it's 5-6 am start or midnight-2am end...just depends on what's happening.

the main thing is, when i vacate, I make it known to the team and my clients that i will be unplugged and will *not* be checking messages. clients get an escalation list for emergencies.

we work too darn hard to work during vacation also...i love what i do but vacation = total unplug, and i guard that like gold.
