Mikael Sjöberg, general director of the Work Environment Authority told Swedish Television that the study's result is very disturbing: "Unfortunately, we can see that those who sound the alarm and ask for help very often do not get any."
While the boys more often suffer physical violence, the girls are more affected when it comes to cyber-abuse. More than one girl in 4 - or 27 % - have experienced that someone was trying to spread false rumours about her for example on internet during the past year.
But it is not just pupils who are the victims of abuse. 5 % of the female staff and 7% of the male staff say they have been kicked, hit or in some other way physically harmed. The study also showed that the situation is worst in Malmö and Helsingborg.
"The schools are not really dealing with their work environment in an acceptable way. What we can do is to primarily carry out inspections and pose demands on them," says Mikael Sjöberg at the Work Environment Authority.
