4466 vs the rest
4466 seems to misunderstand the nature of cargo contracts and why it's necessary for BA to have a cargo aircraft operation at all.
When an airline bids for a cargo contract with a consolidator (Stenna or Maersk for example) it has to contract for the whole consignment and that will inevitably include items that are too big for pax aircraft belly holds and also cargo aircraft only goods.
BA and several other large pax operators hand this 'awkward' cargo to companies like Atlas (who operate for Emirates amongst others) and GSS for BA.
BA mainline rates of pay would make an in-house cargo operation uncompetitive hence the outsourcing.
As to whose jobs they are it's simply a matter of economics and, although BA pilots are mostly insulated from the outside world, having worked for BA for 35 years and GSS for 7 it was enlightening to me to see how lucky I had been to be cosseted by BA for most of my career.
4466 should count his blessings.
