Tesla CEO Elon Musk on Friday e-mailed employees the company would cut its 45,000-strong workforce by around 7%. Musk wrote the firm faces a "very difficult" road ahead, making its electric cars, batteries and solar products cost-competitive with fossil fuels. Musk added Tesla's 4% profit in 2018 third quarter was "small" but the "first meaningful profit in its 15-year history".
