I've heard that there are Fed Jobs for support staff at remote locations that require you to be there for a certain period, 3 months to 6 months for example, and that since you are at a remote location, such as a polar base, you recieve bonuses and/or hardship pay. I saw this covered on one of the major network's news programs at least 2 years ago, and it was mentioned that the people who did these jobs regularly came back because the pay was so high, one example was a kitchen worker who worked for 6 months and recieved 60,000 dollars.
