This week the Royal College of Nursing (RCN) announced its first ever nationwide strike. Pat Cullen, the RCN's General Secretary and Chief Executive, will lead them into industrial action which is expected to start in December.

Born in Northern Ireland, Pat Cullen was inspired by her older sisters to train as a nurse during the Troubles. After roles at Northern Ireland's Department of Health, and Public Health Agency, Cullen joined the RCN's Northern Ireland branch in 2016. Three years later, she led the union's first-ever strike, seeking pay parity for Northern Irish nurses with those working elsewhere in the United Kingdom.

Since 2021, Pat Cullen has been the interim leader of the RCN at national level. Drawing on her experiences in Northern Ireland, she's now campaigning for better wages and conditions for nurses across the UK.
