About two and a half million people in Germany regularly work for eight hours or more in the sun. Their risk of developing skin cancer is twice as high as that of those employees who do not work outdoors. Only a very few of them wear special UV-protective clothing, as recommended by the trade unions and the German Social Accident Insurance Association (DGUV). However, the pressure on employers to require such clothing to be worn and/or make it available, may now increase considerably.
