From 1976 to 1979 I worked as an apprentice at the Company Walter Rau in Hilter. Also in this case the company tried to fire me after 3 months, but I successfully won the trial and I had to be reinstalled. I finished successfully and got the title of a "Chemielaborant".
Walter Rau produced fats and other foods. I was working in food analysis and I learned a lot about food ingredients and contaminants. (I learned specifically how little our food is contaminated....)
