An inflation pay rise (or cost-of-living adjustment) is an increase in salary intended to maintain your purchasing power as prices for goods and services rise.

If inflation is 5% and your salary stays the same, you are effectively taking a 5% pay cut in terms of what you can buy. A 'fair' pay rise at least matches the CPI (Consumer Price Index) rate.
