Great post! :)
The way I see it at work, younger and single employees were the one who is pretty much excited for such opportunities. On the other hand, single moms, hands on dads/parents and those that don't have much choices in their life-home situations felt these kinds of duties is much more of an errand that win-win for both sides. Saves them from jet lags, body clock adjustments, etc.
For a person that has the resources to travel, ample vacation leaves and used to getting this at work, for sure prefer to see the world with their partners/love ones whenever thinking of going out of the country. :)
Looking forward to more of your posting, @guyverckw
