I wonder how many of these overpaid CEO's of American multinationals or Australian big business do unpaid volunteering or charity work...
Charity work is highly recommended to those who chase a steep career.
A two to tree years pause, working for free is seen as a big leading card on the CV of the international MBA guy.
In detail, they end up in a not-so-transparent NGO in Afrika, or an independent bank-sponsored-project in development countries.
I guess they need ambitious people there for their "business", and those who are ready to take part in EVEN THAT, are considered "thrustworthy" afterwards.
But I'm there's a minority that genuinely does it with all their heart.
