I have seen but never been involved in this sort of process, probably because my career has been in unionised environments, but that really is the discussion point here. Do unions protect the weak or lazy?! I doubt if I would be the first to go in my current job, but I know I wouldn't be the last. However, I bet I would be more pursuasive in a capability review, than some who would deserve the job more than me!
