WWW - BA has plenty of F/Os who have no interest in any command other than one on a long haul fleet. The number of trained cadets waiting for work will be quickly absorbed due to the number of retirements, although which pension scheme they'll join under (NAPS or CRAPS) is being hotly debated by BALPA and BA management.
The non-recruitment of pilots is yet another example of pathetic political correctness at BA and is indicative of the state of the airline. I'm sure that once recruitment begins each empire head will ensure that they get an equal number of new feng shui managers and espresso temperature co-ordinators to match the number of new pilots.
