11.4 In a paragraph of FIVE (5) sentences, explain how people are being exploited.
Worker exploitation occurs when individuals are treated unfairly in their employment, often for the benefit of others. This typically involves paying workers extremely low wages that are insufficient to cover basic living costs, trapping them in a cycle of poverty. Many exploited workers are forced to endure excessively long hours in unsafe or unhealthy environments without proper protective gear or benefits. Child labor is another severe form of exploitation, where children are made to work instead of attending school, denying them their fundamental rights. Ultimately, exploitation strips workers of their dignity and prevents them from achieving economic stability and personal growth.
