A Woman's Place UK have written a letter to Penny Mordaunt pointing out that "“It is important for employers to be sensitive to how an employee chooses to self identify in terms of their gender. The regulations do not define the terms ‘male’ and ‘female’ and the requirement to report gender pay should not result in employees being singled out and questioned about their gender.”"
It just seems relentless doesn't it. However often it is pointed out and even acknowledged by officials, they just ignore it every time.
