Tesla's German factory faces production drop and escalating union dispute

Tesla's factory in Grünheide, Germany, is operating at less than 40 percent capacity. At the same time, the company is in a major conflict with the IG Metall union, which has led to a lawsuit and a public war of words with CEO Elon Musk.

Musk has warned the union and threatened to stop expansion plans at the site, where he also wants to build a new 'Cybercab' and robots. In related auto industry news, Volkswagen has overtaken Tesla as Europe's top electric vehicle seller.
