What are the different forms of forced labour?
Bonded labour, or debt bondage, is probably the least known form of labor trafficking today, and yet it is the most widely used method of enslaving people. Victims become bonded laborers when their labor is demanded as a means of repayment for a loan or service in which its terms and conditions have not been defined or in which the value of the victims’ services as reasonably assessed is not applied toward the liquidation of the debt. The value of their work is greater than the original sum of money "borrowed."
Forced labour is a situation in which victims are forced to work against their own will, under the threat of violence or some other form of punishment, their freedom is restricted and a degree of ownership is exerted. Men are at risk of being trafficked for unskilled work, which globally generates $31bn according to the International Labour Organization. Forms of forced labor can include domestic servitude; agricultural labor; sweatshop factory labor; janitorial, food service and other service industry labor; and begging.
