The layoffs include 601 employees at manufacturing facilities and engineering offices in Palo Alto and Fremont, California, according to a May 13 Worker Adjustment and Retraining Notification (WARN) Act notice.
Tesla will lay off 378 employees at the company's Fremont-based manufacturing plant and 223 more employees at its engineering headquarters in Palo Alto during a two-week period beginning June 20, according to the notice.
Among the positions eliminated by Tesla include directors for environmental health and safety and user experience design in Fremont and two directors of technical programs in Palo Alto.
WARN Act filings require companies to provide employees notice of mass layoffs or plant closures 60 days in advance, according to the Texas Workforce Commission.
The notices come less than a month after Tesla said it would lay off more than 3,300 employees across California, including positions in Palo Alto and Fremont.
Tesla did not immediately respond to a request for comment from Forbes.
