I'm not up on employment law but I don't think the FL would be able to, effectively, terminate the contracts of employed professionals owing to the behaviour of their employer. I'd imagine there would be monumental legal strife for the FL if they went that route.
EDIT - That's not to mention the other non-playing staff they employ.
I maybe completely wrong, but are not all players partly signed/registered to the FA as well?
Cut the registration to the FA all the time they are employed by QPR
