It would appear that we’ve had that for rather a long time.
Being 4ft 11in paid off for Edith Kent. Her diminutive stature meant that she could crawl inside torpedo tubes — and helped her to become the first woman in Britain to earn the same wage as her male colleagues while working as a welder during the Second World War.
This week Mrs Kent celebrated her 100th birthday with a tea dance at a hotel with 50 family and friends, including her sister Minna, 105.
Mrs Kent began working at Devonport dockyard in Plymouth in 1941 but was so good that she received wage parity in 1943 — which was unheard of at the time.
Given that such equal pay for equal work is now standard right across the economy, what is it that everyone is complaining about?
