Tesla told staff it was dismissal more than 10% of its workforce on Sunday night, but some workers didn't realize they'd been laid off until they showed up at the company's facilities, five current or former workers told Business Insider.

The layoffs affected engineers and production associates alike. At Tesla's factory in Sparks, Nevada, workers faced a roughly two-hour line to enter the facility Monday morning as a result of badge checks, a worker said.

At the factory, the security team was scanning the badges of workers exiting shuttles that shuttle people between the factory and nearby parking lots, said two current Tesla workers who requested anonymity because they were not authorized to speak on the matter. Typically, security guards inspect workers' badges on site, but they usually don't scan them directly, the two workers said. On Monday morning, officials picked up the laid-off workers and brought them back in separate vans, the two workers said.

Three other former Tesla employees said workers at the Fremont factory were told by security that if their badges didn't work, they were no longer employed.

Tesla employees who were terminated received notification through their personal emails Sunday night and their access to Tesla systems was revoked, four workers said. The company-wide email Elon Musk sent announcing the cuts was delivered shortly before midnight PT on Sunday, according to a timestamp on the first memo from BI.

“We have undertaken a complete review of the organization and made the difficult decision to reduce our headcount globally. Unfortunately as a result, your position has been eliminated as a result of this restructuring.” read a separate email notifying affected employees that they had been terminated, according to a copy seen by BI.

The email was sent directly to the fired staff said the layoffs will take effect immediately and workers will receive information about their departure within 48 hours.

On the same day, Tesla announced layoffs, at least two managers resigned from the company. Group senior vice president of powertrain and electrical engineering Drew Baglino and vice president of public policy and business development Rohan Patel told X that they had left Tesla as of Sunday.

A Tesla spokesman did not respond to a request for comment. Before the layoffs, Tesla employed more than 140,000 workers worldwideincluding over 3,000 at its Nevada plant.

Tesla employees aren't the first to unceremoniously discover they've been fired while trying to get into their former workplace. Last year, several former Google employees told BI that they learned they had been fired when they were could not enter the office.
