Here is our letter, published on Equal Pay Day 2016 in the Financial Times:
Dear Sir / Madam,
In March 2015, women from across the political parties won a change to the law - a promise to bring forth gender pay gap reporting regulations within twelve months. Last year the new government started work on the detailed legislation.
Yet as we mark Equal Pay Day on 10th November, the point at which the average woman stops earning whilst her male counterpart continues to be paid up til the New Year, we still await the final legislation.
To make gender pay gap reporting a success, businesses need time to prepare. With compulsory reporting due to begin from April 2017 for employers with more than 250 staff, we urge the Government to act sooner rather than later.
