Depends who you believe...50% unchanged, 41% up, 9% down according to Unison.
However that is individuals instant hit, not scale changes. My job has gone from Grade 5/6 to just Grade 5 so we have a new, lower ceiling.
No pay change for me or most of my colleagues. Colleagues in post 5+ years get a cut up to £2500. But as there are fewer of them the stats look nice.
Clever thing is they are putting a cap on future salaries and pension committments by cutting off the upper scale from people like me.
