About 350 workers have reportedly been laid off from Uber (UBER) throughout several divisions of the company.

The layoffs affect employees in the company’s Uber Eats, advanced technology group, safety units, and other business teams, Uber confirmed with CNBC on Monday. The news of the layoffs also came with some employees being asked to relocate.

Uber announced the news in a company email from CEO Dara Khosrowshahi, which was obtained by the news outlet. The company said this was the “last wave” in its effort to ensure the company was properly structured for the future.

Khosrowshahi wrote to employees, “As you know, over the past few months, our leaders have looked carefully at their teams to ensure our organizations are structured for success for the next few years. This has resulted in difficult but necessary changes to ensure we have the right people in the right roles in the right locations, and that we’re always holding ourselves accountable to top performance.

“Today is the last wave of a process we began months ago with our Marketing team, and more recently, with Product and Engineering. This time, ATG, Eats, Global Rides and Platform (Rides Ops, CommOps, Safety & Insurance, U4B, and Product Ops), Performance Marketing, and Recruiting have made changes. As part of this exercise, some of our employees are being asked to relocate, and around 350 people will be leaving the company.

“Days like today are tough for us all, and the ELT and I will do everything we can to make certain that we won’t need or have another day like this ahead of us. We all have to play a part by establishing a new normal in how we work: identifying and eliminating duplicate work, upholding high standards for performance, giving direct feedback and taking action when expectations aren’t being met, and eliminating the bureaucracy that tends to creep as companies grow.

“We have proven ourselves to be not only one of the most ambitious and innovative companies in the world, but also one of the most resilient. We’ve always pushed through tough times and come out the other side a better and stronger company—that will continue to be true tomorrow, and every day after.

“As always, we’ll be at the All Hands tomorrow and will dedicate most of the time to answer your questions. Add yours to the slido here.

“Eyes forward—back to building.”

Uber employs about 22,000 workers across all its divisions. This is not the first time the company has laid off workers. A recent round of cuts were announced in early September, affecting about 435 workers.

Shares of Uber stock were up 4.26 percent as of 2:05 p.m. ET on Monday.
