The workers they need are probably not those that led to the failure - at least not most of them - but those that are needed to keep the lights on and the wheels turning. FDIC has a lot of work on their hands going through the books, untangling the messes, deciding who gets what and when - and having some people that know which button to press when and how to fix the system if it crashes is vital. And these people know their employment is at the end - so for them the best strategy is to look for the new jobs ASAP. That's why FDIC is offering them 2x - so that they will take what is knowingly a very short-term job and spend their time helping FDIC instead of spending it looking for the new job. It's not a reward, it's the only way it can work.
