Firstly, paid work gives children real life work experience and helps them develop their characteristics. For example, children will have to learn punctuality is important and being responsible for any given jobs is necessary when they work for other people. They also have to learn to take care of themselves and how to coordinate with their friends at work.
However, they can be easily exploited if not looked after carefully. They have to be given special attention to by their families and governments when working outside. It is very important to make sure that they can maintain a good balance between work and study. This only happens when governments enforce strict policies on the total working hours for children and their work rights. Also, parents have to educate their children on how important their studies are and to make sure their children pay enough attention and efforts to that.
All things considered, it is clear that children should be given the rights to work in more professional environments. At the same time, they have to be well protected from exploitation so that they can maintain a balance between work and study.
