Mass resignations by Twitter employees after Elon Musk's 'long working hours' ultimatum

Following the resignations, Twitter has shut its offices temporarily.

After the resignations, Musk, who seemed unaffected, tweeted, "And … we just hit another all-time high in Twitter usage lol."

"Let that sink in …"

World's richest man and owner of several companies, Elon Musk, has "a few productivity recommendations"that the employees need to follow in order to keep working in any of his firms.

The billionaire informed the employees of Twitter, which he acquired recently, about this through an email, the details of which got leaked on the social media platform.

Musk sent the same emails to staff at Tesla, SpaceX and his other companies, giving suggestions to improve productivity.

Earlier, Musk sent a message to Twitter employees telling them that they had until Thursday to consider whether they wanted to stay with the social media giant for "working long hours at high intensity" or take a severance package of three months payment.

Musk told Twitter staff that anyone who had not clicked on a link confirming "you want to be part of the new Twitter" by Thursday evening New York-time would be considered to have quit.

"Whatever decision you make, thank you for your efforts to make Twitter successful," his message reportedly.

Musk completed a deal to buy Twitter at 44 billion US dollars in October, gaining control of the social network company.

After taking over the reins, Twitter put half of its employees in departments across the company as part of an aggressive plan to trim costs.
