Lets spell this out simply ...
Since 2010 inflation has averaged 2.7%, according to the Bank of England.
So anyone who hasn't had a pay rise for 7 years has basically had a pay reduction.
7 years x 2.7% = 18.9%
Anyone who hasn't had a pay rise for 7 years has in effect had a pay cut of 18.9% on average.
Whilst any pay increase is not to be sniffed at its hardly a flag waving event when people are still on a pay cut. Even if people achieve a pay increase of 4% they will still be sitting on a pay decrease of 14.9% over 7 years.
A proper pay rise would be 19% because even tho the actual rise is only 0.1% it would actually be a rise.
I'm not even sure what you can call a pay rise that isn't a rise.
