Equal pay has been the law for half a century. But women often get paid less than men, even when they're doing equal work. Mostly they don't know because pay is secret. But what if a woman finds out? What should she do?

In Equal, award-winning journalist Carrie Gracie covers her own experience of holding her employer - the BBC - to account and investigates why we're still being paid unequally.

Equal will open your eyes, fix your resolve and give you the tools to act - and act now.
