Tesla told Austin workers on its Model Y and Cybertruck lines to stay home for the week of Memorial Day, three workers told Business Insider.

The break is unusually long, the workers said. Production lines were up and running during the same period last year, they said.

The electric vehicle maker notified employees earlier this week. The workers, who are paid hourly, were told they could either take paid time off or come in for cleaning and training but would not be working on the production line.

Tesla deliveries dropped 13% year over year during the first quarter.
