Power
Are we talking about trade union collective power (Unite) or the power of the individual to have an input to working conditions?
If it is Unite power, then they came to an agreement with BA on a deal. It would have been interesting to see what would have happened if an open vote (no recommendation) would have happened, but we will never know.
How much did individual power affect the passenger prior to this dispute and how often? If the dispute was settled tomorrow, I get the feeling that many that contribute to this thread would still not be happy. These 6000 potential strikers would still be in employment, so there is a big chance that they will be there for some time to come. Surely you want them to be happy at work, because that is what you will experience as passengers, not their terms and conditions.
