The Chukri System is a debt bondage or forced labour system found in Kidderpore and other parts of West Bengal. Under this system a female can be coerced into prostitution in order to pay off debts. She generally works without pay for one year or longer in order to repay a supposed debt to the brothel owner for food, clothes, make-up, and living expenses.
The system creates a workforce of people virtually enslaved to their creditors, and constitutes one of the primary causes for women entering the sex trade. The system flourishes primarily in West Bengal or Calcutta.
