My company is a global company, with offices all over the world, on several continents I, and several other staff members, would love to visit. We were discussing this, as a co-worker mentioned her boyfriend will have a 6-month work stint in Italy, and she was hoping she might be able to swing some work in Italy during his time there. Then came the subject of the 'staff exchange' program we have, where a staff member can exchange positions with another Golder office anywhere in the world for a year (provided the exchange is fairly equal). We've actually worked with one of these exchange staff from Australia when we worked with our Burnaby, B.C. office occasionally.
I of course expressed that would be very cool. Several people (including our office manager) piped up that I wasn't allowed to leave, and one clarified, because it was hard to find someone as capable as me (varying job responsibilities, not just 'admin'). So I said, "If I can find someone as capable as me, somewhere in the world, I can go?" My manager says, "No, because you won't find anyone."
Awwww. It's nice to be needed :)
