Should teenagers work while they are students?
In some countries, teenagers used to have job while they are still
students, but many other advanced countries have a negative
attitude.
According to my opinion it is much better for teenagers to not
work while they are in college. This opinion I am basing on some
reasons.
First of all, I consider when teenager has to work and at the same
time need to get some knowledge, he (she) cannot concentrate well
on his subject, and he is often simply tired. This condition is not
well for studying. I am sure, if teenagers have to work after school,
they do not have enough time for good preparation for studies and
their knowledge progress. I believe that for teenagers it is better to
concentrate on their studies and to make a good foundation for their
future. Also, I think young people are adopting knowledge more
easily than adults. So, this age is really the right time for hard
studying.
When teenagers work, they may loose time for sleep rest and this is
not best way, because
they body are growing up and this might hurt their health. In some
cases, teenagers who work and have some savings can use their
money for not good thing like cigarettes, drugs or alcohols. Some
more reason why is bad for teenagers to have a job because they do
not have enough of professionalism and responsibility. Shortage of
knowledge might become as result bad working. In Russia, for
example, it is not usually for teenagers have a job. I was living in
Russia and I really can say, progress in studies there much effective
than in countries where students have a job, because the first one can
fully to spare the time for studies.
Based on the above discussion, I hold the opinion, I disagree that
teenagers can have a job during they are students because it might

be as result not effective studying.
