Research indicates that adolescents who work more than 20 hours a week during the school year a. are more likely to love their work in adulthood b. tend to hate their jobs and achieve less in school c. create a stronger vocational identity early on d. save more money for college

b. tend to hate their jobs and achieve less in school.

Explanation:

Teenagers have many responsibilities that they need to deal with, and these are usually related to school and family. However, some teenagers are also employed. It can be difficult to balance all these responsibilities, particularly as teenagers are usually not fully used to dealing with them. Therefore, they can run into problems if these become too overwhelming. For example, evidence shows that that adolescents who work more than 20 hours a week during the school year tend to hate their jobs and achieve less in school.

b. tend to hate their jobs and achieve less in school

Explanation:

Entering the job market as a teenager can be beneficial. This is because teenagers achieve a certain economic independence and have more autonomy and responsibility. However, as teenagers do not have an academic background they end up taking less "cool" jobs that require more physical effort. The workday + class hours can also be a very tiring factor that can make teenagers unmotivated with both their job and school. It is estimated that teens who work more than 20 hours a week during the school year tend to hate their jobs and earn less at school.
