Jayaben Desai, known as the sari-clad leader of a two-year industrial action against the Grunwick Film Processing Laboratories in north London in 1976, was named among seven women chosen to mark the 70th anniversary of BBC Radio 4's 'Woman's Hour'.
"Jayaben was this tiny 4ft 8in woman in a sari who had dockers and postal workers from across the land coming to support her on the picket line," said Ayesha Hazarika, an Indian-origin senior Labour party adviser who was part of the panel that picked the one-off Power List.
The repercussions of the strike are considered far reaching for British industrial relations.
The list, which is topped by Margaret Thatcher - Britain's first female Prime Minister, also includes Barbara Castle, Labour MP for Blackburn who brought in the Equal Pay Act in 1970.

More controversial is the inclusion of a fictional woman on the list of seven - Bridget Jones from Helen Fielding's 'Bridget Jones's Diary' series on the travails of a British singleton, played on screen by Hollywood actress Rene Zellweger.
She said: "I hope it doesn't mean everyone's going to binge drink and eat Milk Tray late at night.
"I also hope there was something rather more profound going on, there's something in Bridget's nature which is very British which is ultimately quite decent, quite kind, quite resilient, not judgemental."
The others completing the list of seven, in no particular order, include Germaine Greer, an Australian writer recognised as one of the major voices of the feminist movement; Beyonce, American singer and songwriter; and Helen Brook, who set up the Brook Advisory Centres in 1964 offering contraceptive advice to unmarried women.
The names were unveiled as part of a special 'Woman's Hour' show aired on Wednesday morning and recorded at Buckingham Palace.
