To ask Her Majesty's Government whether they consider that the publication by an employer of information indicating the average pay of women and men respectively in the employer's undertaking would be sufficient in itself to enable the identification of any prima facie direct or indirect sex discrimination within the undertakings and the means of eliminating any such discrimination. [HL3852]

No: we consider it very unlikely that a single figure relating to gender pay over the whole of a large undertaking would in itself be sufficient evidence to found an equal pay or sex discrimination claim in any individual case. What it would do is reveal the existence of any pay gap, and enable both employers and employees to raise questions as to its causes—and as a result take steps to remedy it.
