For instance - lets say that I realise I have a problem with turnover that I want to fix, because my costs of replacing staff are too high. To address that I want to spend 1M on retention activities in a year. Should I spend that on additional vacation days, or should I spend that on extra events for the staff, or on extra training opportunities? If I spend that money, will the impact on my turnover costs be positive enough to warrant the spend?
That's the kind of discussions that always pop up. Being able to quantify the impact would make it easier to do the right thing that both benefits employees and the employer.
