Workers in factories were too overworked and lacked the education to write much about their experiences. But Kashibaba, a Kanpur millworker, wrote and published Chhote Aur Bade Ka Sawal in 1938 to show the links between caste and class exploitation. The poems of another Kanpur millworker, who wrote under the name of Sudarshan Chakr between 1935 and 1955, were brought together and published in a collection called Sacchi Kavitayan. By the 1930s, Bangalore cotton millworkers set up libraries to educate themselves, following the example of Bombay workers.
