The Employment Equity Act section 6, Equal Pay for Work of Equal Value
, legislates that equal work (or work of similar or equal value) must now be remunerated equally …. or differentiated fairly. All policies and conditions of employment need to be scrutinised to ensure that they comply with the legislation.
A survey will give you access to market data so that you can accurately benchmark the remuneration for the same/similar/equal value jobs against that of other companies/entities/organisations.
It is the cornerstone of building your own unique pay scale.
