SAN FRANCISCO — Hundreds of Twitter employees refused Thursday to sign a pledge to work longer hours, threatening the site's ability to keep operating and prompting hurried debates among managers over who should be asked to return, current and former employees said.
The number of engineers tending to multiple critical systems had been reduced to two, one or even zero, according to people familiar with the situation who spoke on the condition of anonymity for fear of retaliation.
The crisis came in response to an ultimatum new owner Elon Musk issued Wednesday demanding that employees sign a pledge to work harder by 5 p.m. Eastern time Thursday or accept three months' severance pay.
In an early sign that the number of those declining to sign was greater than anticipated, Musk eased off a return-to-office mandate he had issued a week ago, telling employees Thursday they would be allowed to work remotely if their managers assert they are making "an excellent contribution."
But it was too late to keep Twitter from a precarious position, several workers said.
"I know of six critical systems (like 'serving tweets' levels of critical) which no longer have any engineers," a former employee said. "There is no longer even a skeleton crew manning the system. It will continue to coast until it runs into something, and then it will stop."
Workers offered varying estimates of how many people remained employed at Twitter, ranging from 2,000 to 2,500, down from the 3,500 or so believed to have remained after an initial round of layoffs this month.
Among those who were said to have declined to sign the pledge was half the trust and safety policy team, including a majority of those who work on spotting misinformation, spam, fake accounts and impersonation, according to one employee familiar with the team.
