Do you mean FPP program or the 34 point pay scale. The FPP scheme is about the best deal going in the UK at the moment. No airline in the UK offers free, no strings attached sponsorship. If you consider that unfair then don't join.
If you are referring to the PP34 scale, the change is that you start in the same salary as before but the annual increments are reduced so it now takes 34 years to reach the top pay point rather than 24. If you consider it unfair then don't join.
