A Twitter exec said she worked more than 75 hours a week since Elon Musk took over, per Irish Times.
The global vice-president for public policy, Sinead McSweeney, said her job has become tougher.
She said Musk was leading Twitter "in an unorthodox manner" and giving staff "mixed messages."
An executive at Twitter said she worked more than 75 hours a week since Elon Musk took charge of the company as a result of his firing a large number of employees, the Irish Times reported.
Sinead McSweeney said in a statement to a High Court in Ireland that her working hours soared to more than 75 in a week since the billionaire took over.
McSweeney, who is Twitter's global vice-president for public policy, provided a statement to the court in a successful bid for an injunction to block Twitter from firing her.
The injunction was granted on Friday after McSweeney claimed she didn't resign but was restricted from accessing company systems and received an exit offer earlier this month.
McSweeney said she didn't respond to Musk's midnight email to Twitter employees on November 16, which told staff they either had to agree to an "extremely hardcore" culture by clicking yes to a form in the email, or their resignation would be accepted.
The vice-president, who has worked at Twitter for more than a decade, said she regularly works more than 40 hours per week as required by her employment contract.
McSweeney also said her job has become tougher since Musk took over the company but that she took no issue with "putting my shoulder to the wheel," the Irish Times reported.
Musk has given staff "mixed messages" and is leading the organization "in an unorthodox manner," McSweeney said, according to the report. She added that the chief executive has "with no apparent logic" fired and rehired staff.
The "Chief Twit" cut almost half of Twitter's workforce a week after his takeover deal was finalized on October 27. After his November 16 email issued the remaining staff the ultimatum, around 2,000 people quit and turned down his offer. Twitter later asked some staff to return to the company.
Twitter and McSweeney didn't immediately respond to requests for comment from Insider.
