Welcome to another week, readers. Writing to you from New York, I'm your host, Jordan Parker Erb.

Over the past few weeks, we've watched as Elon Musk has shifted Twitter's culture. One of the biggest transitions was his decision that employees will be fired unless they work at an "extremely hardcore" rate to build "Twitter 2.0."

But Musk isn't the only one upping the expectations for workers. Across the industry, tech CEOs are asking their employees to step up — or step aside.

Let's get started.

1. It's not just Elon Musk: Major tech CEOs are asking employees to step up or risk getting fired. After taking over at Twitter, Musk notoriously asked staffers to work "long hours at high intensity" or quit. But other tech CEOs from firms like Meta and Amazon have also been turning up the heat on employees.

• At Facebook, for example, CEO Mark Zuckerberg reportedly told staff in early July that he would be "raising expectations and having more aggressive goals."

• Alphabet, too, has outlined plans to "make the company 20% more productive" when CEO Sundar Pichai sounded the alarm that employee productivity needed to improve.

• Already famously frugal, Amazon urged the company during an all-hands meeting in early October to "double down on frugality" and told employees to "accomplish more with less," according to leaked slides from the meeting.

• Though their language was more diplomatic than Elon's, the message was still similar: Employees will be expected to step up or find somewhere else to work.

Here's what more tech CEOs are expecting.
