Musk urges 'barnacle' purge of Tesla contractors at struggling factory

Tesla employs a large number of temporary workers at its auto, solar energy and battery storage factories, although the approximate number, or the proportion of total workers, remains a company secret. The company employed about 37,500 total workers at the end of 2017. The United Auto Workers is attempting to organize workers at the Fremont plant, which employs about 10,000.
