Latest figures show that 260,000 teenagers have a Saturday job compared with 435,000 in 1997.
The trend is not just recession-related but the result of an increasing expectation that young people should stay on at school, as well as a dwindling number of Saturday jobs, according to the report. Many of the jobs that young people do, such as bar work, are in long-term decline, and are forecast to stagnate or decline further over the next decade.
