Per BI: A former Twitter employee is suing the company, alleging that Elon Musk's new work demands forced disabled workers to resign.

The class action lawsuit, filed Wednesday in the San Francisco federal court, highlighted how Musk told Twitter employees this week that they would have to "work long hours at high intensity" and "be extremely hardcore."

The lawsuit was filed on behalf of Dmitry Borodaenko, an engineer laid off earlier this month. He accused Twitter of breaking state and federal discrimination laws. Borodaenko said he is a cancer survivor and was fired after telling his manager he preferred to work from home because he was at "extra risk" from COVID-19, per the lawsuit.

"Many disabled employees who have, and would continue to, perform their jobs effectively have felt that, because of their disability, they will not be able to meet this new heightened standard of performance and productivity," said the lawsuit, seen by Insider.

"Thus, many disabled employees have felt forced to resign," it added.
