Twitter's workforce reduction is unmatched on a percentage basis, in comparison with other big tech companies like Google, Amazon, Microsoft and Meta which have cut tens of thousands of employees worldwide.

Twitter is facing a host of lawsuits and other legal actions on behalf of former employees over lay-off and benefits issues, according to a report by the San Francisco Chronicle.

The company also said in a recent legal filing that "Twitter, Inc. has been merged into X Corp. and no longer exists."

According to the legal filing, X Corp. is a privately held corporation. Its parent corporation is X Holdings Corp.
