Youngsters should thank their parents for their care and support. As turning 18 means becoming an adult, some believe teenagers at this point should get a job to contribute to household spending. Although it is important to become a more responsible person, I don't think 18-year-olds should have part-time or full-time jobs.
To start with, juggling school and work is difficult for most young adults, so it would cause a great deal of stress. University graduates often complain about how difficult it is to get a job. So it's likely that 18-year-olds who want to work in their last year of school or first year of university will struggle to find a job.
At the same time, they have school work, revision and public or internal exams to cope with.
