I work for an employer that is brilliant for everything except pay. We've recently been told that HR are in the process of salary benchmarking. I know for a fact we're all paid about 10 to 15k less than the industry average. This means a really high turnover as people stay long enough to get training and experience under their belt, then leave for decent pay. How optimistic should I be about this salary benchmarking leading to a decent payrise?
