So, it's OK for you to "nag" about poor pay, yet not for passengers to "nag" about what they have paid for? Where do we get our money, out of thin air?
I understand it is hard-earned money you are using, just as we deserve more for our efforts. The average economy passenger earns in the region of around £20-25k, while we earn less than half of that. So next time you check-in, it is very likely that the poor sod behind that desk is having to work double shifts to barely make ends meet, think about that before you ask him or her for an upgrade or nag about that strike. Just as passengers want what they paid for, we want what would be a reasonable pay in return for our efforts.
