Explanation: Trade unionism spread over to many urban centres and organised labour strikes. The communists played a prominent role in organising the working class throughout this period.

The Kharagpur Railway workshop strikes in February and September 1927, the Liluah Rail workshop strike between January and July 1928, the Calcutta scavengers’ strike in 1928, the several strikes in the jute mills in Bengal during July-August 1929, the strike at the Golden Rock workshop of the South Indian Railway, Tiruchirappalli, in July 1928, the textile workers’ strike in Bombay in April 1928 are some of the strikes that deserve mention.
