It is hoped that the government will not take Morgan’s side in the argument, as a new report, High heels and workplace dress codes (put together jointly by the Women and Equalities Commission and the Petitions Commission) has asked that they take action against sexist dress codes in the workplace.

The report recommends that the MPs “take urgent action to improve the effectiveness of the Equality Act” and that employment tribunals should be able to ask for more effective remedies, such as financial penalties, for those employers who breach the law.

It says: “It is clear that there are not currently enough disincentives to prevent employers breaching the law. While negative publicity will be a disincentive for many employers, this cannot and should not be relied on to prevent unlawful discrimination.

“The Government must substantially increase the financial penalties for employers found by employment tribunals to have breached the law.

“Penalties should be set at such a level as to ensure that employees are not deterred from bringing claims, and to deter employers from breaching the legislation.”
