Drug testing at work is being introduced in more industries. The test is a privacy-sensitive measure that is seen as a physical intervention.

It is required that the employer has sufficient reasons to carry it out. As an employee, you may have problems if you do not want to take the test, says Petra Herzfeld Olsson, professor of labour law at Stockholm University. The tests are an important part of working to prevent addiction, says Magnus Nyqvist from occupational health company Feelgood.
