This open letter from AK President Renate Anderl and ÖGB President Wolfgang Katzian is addressed to the members of the EU Parliament, as key decision-makers in the negotiations on the Artificial Intelligence (AI) Act. It is important that AI as a technology is regulated at the European level. However, the AI law must allow member states to maintain existing labor (constitutional) law provisions and to experiment with national regulations (collective agreements) on AI in the workplace. Clarification before a decision is made in the law is absolutely necessary.
