As others have said, you'll have no say in where you are posted and have to accept what's given to you.
If this posting affects you extremely negatively (and it would have to be an extreme I suspect) then you could always try for a compassionate posting somewhere that would enable your problems to be sort out, once your feet are firmly under the NATS table so to speak.
