I'd never be in favour of anything less than an RPI pay increase (4.8%)...
One of the 3 reasons used during the pension briefings to convince us that a change was needed was that long-term inflation was high.
To be told that inflation has now fallen and therefore we should accept a pay freeze feels like we are expected to believe anything that we are told (although I do think that we have been somewhat guilty of that! - too many have listened and taken the information "at face value" and not bothered to check what they have been told).
