The economic activity of the teenagers in our country is limited mostly to a part-time employment like a part-time job, so they receive unfair discrimination or treatment in wage(s), working hours, working environment etc. In this case, they put involuntarily themselves on the job market owing to economical conditions, or in numerous cases, they work and study together. It is reality that teenagers have little reward for working rights. Therefore, it is highly necessary that we should have much consideration and interest about how we protect their working rights effectively. In this paper, we intend to look into the change of the awareness on teenager workers, the reinforcement of the support for the labor-related laws such as the Labor Standards Act and the Minimum Wages Act, and the activation of a program for the promotion of teenager work.
