When the EU Pay Transparency Directive comes intoforce in 2026, the pay gap will start shouting in every company. We decided toshout first — and to tell this story the way we see it: as a concert tour. Fiveacts, sixty years, one direction. Because the road to equal pay wasn't a single pieceof legislation. It was a series of breakthroughs, each of which widened who thelaw could see at all — and each time it was driven forward by specific peopleand events, not by governments acting on their own initiative. That's animportant context for companies: these changes never waited for a convenientpolitical moment. They won't wait now either.
Act I — United States, 1963. The first federal equal pay law banned pay differences for "substantially the same work". It was a breakthrough, yet one that saw only a single axis — sex — and only within the same establishment. It couldn't recognise women discriminated against for several reasons at once.
Act II — United Kingdom, 1970. The law was forced from below by a strike of 187 machinists at a Ford factory. But even equalising pay for the same work didn't close the gap — because its quiet engine turned out to be motherhood.
Act III — European Union, 1975. The leap from "the same work" to "work of equal value". This struck at the heart of the gap: the systemic undervaluation of occupations dominated by women.
Act IV — European Union, 2006. The quietest breakthrough: the burden of proof shifts to the employer. The law stops requiring proof of ill intent and starts catching hidden and systemic discrimination — including on the grounds of age or disability.
Act V — European Union, 2023. Transparency as a tool. The light that exposes every pay difference that can't be justified — and marks the tour's next stop: 2027, your company.
Because the 2023 directive turns this story from ahistory lesson into a task for tomorrow. In the articles that follow, we setout each act separately — with data and research that no poster could hold —and at the end we show what sixty years of law means, in concrete terms, foryour company today.
