Working can have benefits for students, but all too often they are exploited in dead-end jobs. Most of the part-time work students can get is low-paid and low-skilled. It does not stretch them mentally and teaches them little compared to school. Dodgy bosses often treat teens worse then regular employees, for example not giving them holiday pay or proper training. Sometimes the work they do is unsuitable or even dangerous. It is interesting that a Scottish study found very few employers had bothered to get the permits needed for their student workers.
