The definition of child labour usually means work done by children
under the age of 15 that is full-time, and therefore interferes with
their education. Also, work that is exploitative, and work which
damages their physical, mental, social or psychological
development. It does not mean work done by children after school,
on weekends or during holidays to help their family. Some of the
worst child labour abuses – incredibly – involve 4 and 5 year olds
working full-time.
