The mother of unfairness, one could say, is the disappointment of not getting paid at the end of the month after an honest month's job. This is not to imply that the salary never gets paid, but the uncomfortable experience of a delay could span days or even months!
The public sector however has various manifestations of pay inequity and unfairness, which the job evaluation exercise aims to address. In Government, there are parallel and overlapping salary policies and guidelines which mean that one size currently does not fit all.
