Say that in the future hibernation is possible and someone makes an offer for you to go to a distant planet apply your talents and skills for 1-5 years and get back, I foresee two major problems with finding anyone who would agree to this.
1. The people you know, even if they can live indefinitely always have some risk of an accident. If you wait for 100-500 years, some are not going to be alive when you return.
2. This is the major problem: in 100-500 years the company that sends you to space could very well be bankrupt or long gone. Even if it is a country that is paying for you, you have zero guarantee you will actually get any payment in 500 years. And even if your boss will pay you, how the hell can you negotiate how much that rate is going to be in 500 years (think of inflation etc)? In an age of AI, things will become much less predictable, resources like gold can be found or not found in space and their value may fluctuate wildly as a result. Even if you get paid as % of the average salary, the average salary could be very low because the basic things may become close to free, but you still can't buy anything good. What can you use as a reference point for your salary when the future is so unpredictable?
The only way I can see people wanting to do this is if hibernation itself is expensive or not available for everyone and it may be less of a risk to hibernate in space. So people would just get paid by the hibernation experience (to get to the future faster).
