Apple Inc laid off more than 600 employees in California as part of the decisions to end its car and smartwatch display projects, according to filings with the California Employment Development Department.

The Cupertino, California-based company filed eight separate reports to the state to comply with the Worker Adjustment and Retraining Notification, or WARN programme. Companies must file a report to the state agency for each California address that includes employees affected by a layoff. At least 87 of the people worked at an address corresponding to a secret Apple facility for its next-generation screen development, while the others were located at buildings related to the car project.
