Tesla’s two U.S. plants are back on track, with employees taking unpaid leave until the end of May.

Tesla’s Fremont assembly plant and Nevada’s super-battery plant, which has been out of production for more than a month, are now back on track, and Tesla is recalling employees. Tesla’s Fremont assembly plant and the Nevada-based battery-making superfactory are back on track, stemming from an email from Valerie Workman, Tesla’s head of human resources, to employees.

Tesla's two U.S. plants are back on track, with employees taking unpaid leave until the end of May.

In an email to employees Wednesday night local time, Walkerman said their two plants were back up and running.

In the email, Valerie Walkerman also said Tesla’s normal attendance would resume on Friday, and that employees who still want to be home because of concerns about the outbreak would need to submit a written document to the personnel department that would continue unpaid leave until the end of the month after being approved.

Media reports show that according to Tesla’s attendance rules, those who are not allowed unpaid leave not to work normally, will deduct the corresponding points, late is deducted 1 point, absence is deducted two points, each employee deducts points of 5 to 6 points, may be fired.

Restoring attendance and recalling employees to work at the plant means Tesla needs to protect its employees’ safety, and Valerie Walkerman said in an email that they will take health-safety-related precautions, provide masks for employees who need them, and require temperature tests for employees entering the plant.
