I would suggest that the union leaders are doing a better job per £ of salary defending their members T&Cs and pensions than the military leaders are!
I'd agree with that:
Last 3 years of military pay 'rises': 0%, 0%, 1.5(?)%
Last 3 yrs of train driver pay rises: 5.5%, 3.7%, 3.2%
Most staff are on circa RPI + 0.5% to 1.0%
On the other hand, train driver's don't get an annual increment roughly equal to 1.3%, and the final salary pension is salary sacrifice.
