The UCS Work In was a turning point in history at a British level. It was a heroic victory of the Scottish working class, led by shop stewards many of whom were Communists.

Upper Clyde Shipbuilders (UCS) was a British shipbuilding consortium created in 1968 as a result of the amalgamation of five major shipbuilders of the River Clyde in Scotland. It entered liquidation amidst much controversy in 1971, leading to a famous "work-in" campaign at the company's shipyards, led by a number of Communist shop stewards, incuding Jimmy Airlie and Jimmy Reid.

Professor John Foster who co wrote the seminal book on the Work - In, and is also a Communist, addressed a public meeting of Clydebank Trades Union Council in October 2011 to celebrate 40 years of the world famous Work In, and to draw out the lessons which we can learn from it today in our fight against another Tory government and their cuts agenda.
The full videos of that meeting are online on the Clydebank TUC website http://clydebanktuc.org/
