University of North Carolina conducted a study in which they asked about working conditions for teenagers who often have part-time jobs during the school year.

U.S. teenagers, aged 14 to 18, work mostly at retail and service jobs and spend working an average of 16 hours a week. After questioning 928 teenage workers, the researchers found that their jobs are often dangerous and unsupervised and that working conditions often violated federal law.

Teens reported that more than often they have been exposed to multiple hazards, needed to use dangerous equipment or work long hours during the school week. Consistent training and adult supervision on the job are also not provided regularly.

Federal law prohibits teens under 18 from to use dangerous equipment such as slicers, dough mixers, box crushers and paper balers, or serving or selling alcohol in places where it is consumed. However, over 50% of the boys and around 43% of the girls have used such equipment and often worked long hours or after 7 pm on school nights.

Working late can have negative effects on teenage school performance. Besides that, they are also being exposed to possible violence especially when working in retail and other service sectors.

One third of teens reported not receiving any safety training but those who did were never trained how to deal with burglaries or fights among co-workers.
