I don't want to comment on how LGW got its terms and conditions as I believe that has been discussed.
Was it right or wrong to allow it to happen?Another 80 pages could follow and that too has been done.
When all the changes were made the LGW crew were given various options.No one had to stay there if they didn't want to.
The ones that stayed made that informed decision themselves.New crew were recruited onto new terms etc. In short,the crew knew when they were offered the job what it would entail and what their pay structure would be.That could possibly be why they are "happy" with their lot.
A new pay scale was introduced at LHR and crew joined with a new contract and were happy to do so.I don't think people would leave one job to go to another if they were unhappy at the outset.
Don't want to upset any one as I realise that this is an emotive thread.
