Germany's largest trade union, IG Metall, is supporting Tesla employees/executives who were told by Elon Musk in a leaked email last week that they must return to in-person work immediately, at no less than 40 hours per week, or resign. Musk explained in a tweet that the move was to provide more equality between their executives and their factory workers, who have been required to work in person during the pandemic. The district leader for IG Metall, who represents over 2 million German workers in the manufacturing industry, responded with "whoever does not agree with such one-sided demands and wants to stand against them has the power of unions behind them in Germany, as per law."
