^ I think ground staff are more tuned into what would happen if we demanded a pay rise. (In fact, when i moved to the ground, i found that in general - the ground staff are more, well, grounded!) We'd simply be replaced by agency staff like they have at LGW and the outstations quicker than you can serve 300 economy meals.
It's not a 'them against us' situation at LHR - we actually get along with all levels of management. All service sector is bad pay unless you're top brass.
Some, like VS is worse than others but each company has it's pro's and cons and like i've said before i wouldn't want to work for any other other company, and i doubt neither would most crew moaning about a pay rise as they would have left already for greener pastures.
