Sure, a teenager who works part-time may be learning something about responsibility, teamwork and
money management. But research has shown that when teens work for 20 hours or more a week, as nearly
half of US 12th graders do during the school year, the job isn't just good practice for the future. Overworked
teens give up some sleep and exercise, spend less time with their families, and cut back on their homework.
That is not even the worst of it. A 2008 report by the National Research Council and the Institute of
Medicine showed that students who worked 20 hours a week had lower grades, higher dropout rates (退学率),
and were less likely to go to college.
Most of these hardworking teens get jobs in the service industry, with more than half employed in
restaurants and stores. A quarter of them are employed in the health-care industry, while 8% work in
agriculture.
Soon, teens may not be the ones deciding how many hours a week they want to spend on part-time jobs.
A labor agency has asked Congress (国会) to give the US Department of Labor instructions to limit the
number of hours youngsters under age 18 work during the school year, and Congress has agreed to.
