There are so many re-competes and re-bids for contracts that are supposed to be multi-year, that pretty much every fucking year a new company comes in and under-bids a contract. The company isn't going to take the hit, so the employees basically get to re-apply for the same position at a lower salary.
The government claims that this system was developed to ensure fairness to the companies bidding on jobs, but it seems an awful lot like the real purpose was to drive employee wages down. Hopefully it doesn't start to drive down private sector wages in the DC area.
