Automaker Stellantis  (STLA) , which manufactures top car brands such as Jeep, Chrysler and Dodge, laid off about 400 of its U.S. corporate employees late last week, and it used a sneaky new tactic to do it.

The company reportedly sent out a notice to its employees informing them that it will implement a “mandatory remote work day” for “all U.S. Salaried Non-Bargaining Unit” employees in its engineering and technology department on March 22.

In the alleged email to employees, which was leaked on social media platform X, Stellantis claimed that the reason for the mandatory remote work day was because the company was holding an “important operational meeting that requires specific attention and participation.” The email also states that “employees are expected to work from home” unless a manager tells them otherwise.
