Some Twitter staff were cut off after missing a Saturday deadline from Elon Musk because they didn't check emails at the weekend, report says

• Some Twitter staff were cut off because they didn't see Elon Musk's NDA pledge in time, per Platformer.
• The report said the deadline was Saturday, but some staff didn't check their emails at the weekend.

Some Twitter employees lost access to work systems after they failed to sign Elon Musk's anti-leaking pledge on Saturday because they didn't check their emails over the weekend, Platformer reported on Monday.

Musk on Friday sent an email to Twitter staff, saying the company could sue workers who leak confidential information, a source told Insider.

Employees had until 5 p.m. PT on Saturday to sign a pledge agreeing not to leak and to abide by non-disclosure agreements they signed when they joined the company, according to the email which Platformer's Zoë Schiffer obtained and cited in a Twitter thread on Saturday morning.

However, some staff didn't respond to the pledge because they weren't looking at their emails over the weekend, per Platformer's recent report. These employees discovered on Sunday they had been cut off because they were unable to access company systems, the report said.

Twitter then sent another email about the pledge to its workforce, Platformer reported. The company requested staff to send an email to a certain team, confirming their decision to remain loyal to their non-disclosure agreements, the report said. The email said employees had until December 15 to respond, per Platformer.

More than 100 Twitter employees were deactivated from Slack by Sunday afternoon, according to Platformer's report. It was unclear whether all of the 100 staff failed to check their emails at the weekend, or whether some simply refused to sign the pledge.

Twitter didn't immediately respond to Insider's request for comment made outside of normal US working hours.

Musk wrote in his Friday email: "As evidenced by the many detailed leaks of confidential Twitter information, a few people at our company continue to act in a manner contrary to the company's interests and in violation of their NDA," according to Schiffer.

He added: "This will be said only once: If you clearly and deliberately violate the NDA that you signed when you joined, you accept liability to the full extent of the law & Twitter will immediately seek damages."
