META, the company that owns Facebook, Instagram and WhatsApp, has announced plans to lay off 10,000 workers. It will be the second wave of mass layoffs by the tech giant, which laid off 11,000 employees last November. Meta CEO Mark Zuckerberg said the cuts would be “serious.”

Zuckerberg confirmed to employees that, along with the 10,000 job cuts, 5,000 vacancies at the company will remain unfilled. In the letter, he told employees he believed the company had experienced a “wake-up call” in 2022 when it experienced a dramatic slowdown in revenue.
