Twitter began layoffs on Friday that will cut roughly half of its 7,500-person workforce, the company announced in an email. “Today is your last working day at the company,” the email said, which ABC News has reviewed. The subject line read “Your Role at Twitter” and was sent to the personal email addresses of those laid off. The email reiterated that about 50% of the workforce at Twitter has been impacted. #elonmusk #twitter
