A former Tesla employee claims he was fired after raising complaints about how the extreme heat of his work environment was causing his hearing aids to malfunction. The man, Hans Kohls, made the allegations in a lawsuit against the Elon Musk owned automaker, which was filed Monday and obtained by The Independent.
