When it comes to shining a spotlight on the difference between male and female pay, many companies are sceptical, hesitant, and even fearful. The discourse often focuses on risk—the threat of being named and shamed.

Thomas Piketty, in his book Capital in the Twenty-First Century, partly attributes the rise in inequality during the latter part of the 20th and early part of the 21st centuries to “the rise of the super-manager”.

The beginning of 2016 brought with it further controversy about executive pay.
