TEENS AND JOBS

Adolescence is that difficult period of time when carefree children transition to responsible adults...we hope. That is the goal after all-for teens to develop into mature, productive, responsible members of the community. One method for assisting this transition is obtaining part-time employment. A job can help teenagers better develop their identities, obtain increased autonomy, achieve new accomplishments, develop work experience, and become more independent of their parents.

According to the US Department of Labour, 50 percent of American teenagers hold informal jobs, such as baby-sitting or yard work, by age 12. Boys tend to begin their jobs at younger ages and work more hours than girls. By age 15, nearly two-thirds of American teens have had some kind of employement. By the time teens graduate from high school, 80 percent will have held a part-time job at some time during the school year. The average high school student works 20 hours per week, and about 10 percent work full time ( 35 hours or more).

There are many obstacles to teens obtaining employment. Finding reliable transportation is critical, and that can be difficult if the job is not close by and the teen's parent(s) work(s). Fighting stereotypes that employers have about adolescents, such as poor attitudes or lack of skills, can be challenging. In this particular economy, there aren't very many job opportunities for teens.

Teens want to work for a variety of reasons, but more than half report their involvement in work is motivated by the desire to buy things. Typically, teens spend their money on car expenses, recreation, clothing, education, saving for college, and helping their families with living expenses (e.g. rent, groceries)
