Tesla Inc. (NASDAQ:TSLA) is increasing wages for its factory workers in Germany amid unionization efforts. The company announced a package of wage increases during CEO Elon Musk's visit to the Berlin Gigafactory. Tesla has been facing pressure from Germany's IG Metall union, which seeks to unionize the plant. A smaller industrial union representing Tesla service workers in Sweden has gone on strike. The United Auto Workers union in the US is also targeting Tesla's factories. Unionizing could significantly increase Tesla's labor costs.
