Tell that to every government contractor. Many companies (that I'd wager you wouldn't take issue with) exist due to the contracts they have with a single government organization.

But the government doesn't tell those companies "you cannot work for anyone but us." The government doesn't tell those companies "your employees must work these hours" (it may say "we require coverage for X period of time").
that kind of setup is actually fairly rare -- most of the work done in this sector is by large companies that have tens to hundreds of concurrent contracts from various government agencies. speaking from experience
