context: Finland has a law on young workers in 1993. It states that a person who has not reached the age of 15 or has not yet completed his compulsory education may not be employed. However, in the year in which a person reaches the age of 14, he or she may be taken up to half the school holidays or temporarily during the school year for light work which does not adversely affect his or her health or development or impair his or her attendance at school. There are also specific provisions on working time and health and safety at work for workers under the age of 18. [4]
