Muttley,
You might as well start. In your eyes what would it take to remedy the situation?
For me a good start would be to uncap SNCOs on PES (A). Why ? Well although level 22 is a decent salary people have a need to feel that they are moving ahead in life, both for personal pride and self-satisfaction. A WO1 on level 22 could potentially sit there for 10-15 years with NO prospect of promotion and NO prospect of a payrise*, I know that this appeals to some people but I regard it as stagnating.
*Annual increases granted
