Elon Musk’s massive Twitter layoffs are here. Are they legal?

Twitter broke its silence on the long-rumored layoffs in a companywide memo on Thursday night, according to multiple major media outlets. The memo did not state how many of Twitter’s 7,500 employees would lose their jobs, but it said all affected workers would be informed by noon Eastern time on Friday.

By late morning, reports were emerging of entire teams being laid off, including the curation team, which helped tackle misinformation and contextualize the “Explore” page, and the machine learning ethics, transparency and accountability team, which was studying algorithmic amplification. The company also reportedly laid off most of its extensive communications team.

Civil rights groups also began publicly pressuring advertisers to pause buying ads on the platform given the layoffs’ likely effect on Twitter’s content moderation capacity.
