Who are the female union leaders overseeing UK strike action?

Four women at some of the biggest unions are on the frontline of the fight for better pay and conditions

Christina McAnea is the general secretary of Unison, the UK's biggest union. Brought up on Glasgow's Drumchapel estate, McAnea left school at 16 to join the civil service, before going to university at the age of 22 and earning a degree in English and history.

A longtime union official, the no-nonsense McAnea has couched Unison's demands for better pay and conditions for NHS workers, who include paramedics and ambulance staff, as a battle for the future of the health service.
