The Coimbatore strike of 1922 was a major strike by textile mill workers in Coimbatore, India. The strike lasted for 10 months and was led by the Coimbatore Labour Union. The strike was successful in achieving a number of demands, including a wage increase and improved working conditions.
The strike was sparked by a number of factors, including low wages, long working hours, and poor working conditions. The mill owners were reluctant to improve the conditions of the workers, and the strike was the only way for the workers to get their demands met.
The strike was a major turning point in the history of the labour movement in India. It showed the power of the working class to unite and fight for their rights. The strike also led to the formation of the All India Trade Union Congress (AITUC), which is one of the largest trade unions in India.
