Tesla factory workers reveal pain, injury and stress: 'Everything feels like the future but us'

Exclusive: CEO Elon Musk defends workplace, saying '[we are not] just greedy capitalists who skimp on safety' - and declares his $50bn company overvalued

When Tesla bought a decommissioned car factory in Fremont, California, Elon Musk transformed the old-fashioned, unionized plant into a much-vaunted "factory of the future", where giant robots named after X-Men shape and fold sheets of metal inside a gleaming white mecca of advanced manufacturing.

The appetite for Musk's electric cars, and his promise to disrupt the carbon-reliant automobile industry, has helped Tesla's value exceed that of both Ford and, briefly, General Motors (GM). But some of the human workers who share the factory with their robotic counterparts complain of grueling pressure - which they attribute to Musk's aggressive production goals - and sometimes life-changing injuries.
