Who actually pays for what and how is so mangled that if you want to reallocate someone to another project (or even just pay them out of a different pool of funds!) often the easiest approach is to rehire them through a contractor, or a different contractor.

This is especially useful when projects are wound down. Let's say you've contracted to an org for support or management on a project that you want to kill, you've already obligated some amount of funds, and you don't really want to make that organization angry by ripping millions away from them (the pool of contractors is not large). What to do? Well, you could take Joe and give him a raise by suggesting he work for the contractor instead of you directly. Money's already spent, anyways. So you save your own money that you can use for your pet projects or whatever, Joe gets a raise, the contractor doesn't get a termination that pisses everyone off. Everyone happy, right? Smh.
