Musk sent a companywide email to remaining employees of the social media business on Wednesday, demanding they commit to working long hours at high intensity or receive three months of separation if they did not.

The companywide ultimatum was sent around midnight in San Francisco time and was shared with CNBC. He fired veteran engineers at the company after they criticized him in public.

Since taking over, Musk has made a number of changes to the micro-messaging service. One change that he insisted the company roll out quickly had to be withdrawn.

A blue check mark that looked like the mark previously reserved to show an account was verified or official was included in the price of the Blue subscription service.

The paid subscriber checkmarks were purchased by a lot of people who pretended to be celebrities, brands and politicians.

Accounts were used to impersonate Eli Lilly. The fake account caused a serious problem when they posted, "We are excited to announce that diabetes is free now." The fake account stayed on the platform for hours before it was taken down. The Eli Lilly account apologized to those who had been deceived by a fake Lilly account.

The stock price of Eli Lilly plummeted after the false message was posted.

Musk is going to release a new version of BlueVerified on November 29th.

There is a subj. There is a fork in the road.

The time stamp was removed from the date.

To succeed in an increasingly competitive world, we will need to be very hard core. Working long hours at high intensity will be the result. A passing grade will only be achieved by exceptional performances.

It will be more engineering driven. Design and product management will still be important, but the majority of the team will be written code.

I think this makes sense because at its core, it's a software and server company.

Three months of separation will be given to anyone who hasn't done so by tomorrow.

If you make a decision, thank you for the work you've done.

There is a person named "Emil."
