- Tesla told Cybertruck workers they didn't need to report to work for three days this week.
- Two factory workers told BI they were told a battery supply issue caused the schedule change.
- Tesla shortened production hours for the Cybertruck line earlier this year.
Tesla is facing a battery supply issue on its Cybertruck line, according to two Cybertruck factory workers.
The two workers told BI they were notified by production supervisors that a recent three-day reduction in Cybertruck manufacturing shifts was the result of an imbalance in the production line — specifically, a lack of working batteries for the truck.
The battery issue caused the line to get "backed up" over the past week, one of the workers said.
Tesla didn't immediately respond to a request for comment.
Employees on the Cybertruck production line were told on Monday they wouldn't "need to report to work" from December 3 to December 5, according to a memo first viewed by Business Insider. In the memo, no reason was given for the schedule change.
Workers were told they'd still receive eight hours of pay for each day they'd been scheduled to work. The regular schedule would resume on December 6, according to the memo.
The schedule for the line has been inconsistent since late October, five Cybertruck workers told BI, and one employee said he began looking for new jobs as a result. The employee said he was no longer working 40 hours per week; earlier this year, by comparison, workers were collecting overtime, he said.
In April, the company shortened shifts for the line, according to an internal memo viewed by BI. Over the past month, the company has further shortened shifts for some of the workflows on the Cybertruck line, three workers said.
Last December, Reuters reported that Tesla was struggling to produce the Cybertruck's 4680 battery at an industrial scale. The battery is also used for the Model Y.
One Cybertruck worker said he felt Tesla was still "working out the kinks," adding that the line has been constantly adapting to increase efficiency and the quality of the truck, including changing factory practices to address recalls.
The carmaker has issued six voluntary recalls since the vehicle was released late last year. Most recently, Tesla issued a recall due to a faulty drive inverter that could cause the truck to lose propulsion.
The Cybertruck is the best-selling electric pickup in the US, according to Kelley Blue Book. When deliveries of the vehicle first started, the carmaker had more than 2 million reservations, according to a tally reported by Electrek. Tesla has delivered more than 27,000 Cybertrucks, per its most recent recall.
There have been some signs that demand for the product may be slowing. The company stopped selling the Foundation series version of the truck in October and lowered Cybertruck leasing prices earlier this week.
