The electric motor firm's CEO - who has just welcomed a son named X Æ A-12 with musician Grimes - took to Twitter to announce he will be resuming production at their Fremont factory in California factory against Alameda County rules.
Over the weekend, the billionaire businessman threatened to move his California plant to Texas or Nevada.
And in an email this week, Tesla he responded to an order from California's governor allowing manufacturers to resume work and stated that he has invited furloughed employees to return.
On Monday (11.05.20), he announced: "Tesla is restarting production today against Alameda County rules.
"I will be on the line with everyone else.
"If anyone is arrested, I ask that it only be me."
According to Reuters, part of the email to staff, which had the subject, 'Furlough Has Ended And We Are Back To Work in Production!', reads:
"We're happy to get back to work and have implemented very detailed plans to help you keep safe as you return."
Tesla has been warned by Alameda County health officials that it should not have opened without meeting certain local safety requirements.
In a statement they added that they "hope Tesla will likewise comply without further enforcement measures."
Musk sued the county over the weekend, accusing them of violating California's constitution by going against Newsom's order for manufacturers to re-open.
