In a lengthy email full of management speak which disparaging remote work, which had been a tenet of Nothing CEO Carl Pei's workplace policy since its creation four years ago, Pei explained why his 450 employees needed to come to the office five days a week.

"Remote work is not compatible with a high ambition level plus high speed," Pei said in an email to staff, which he shared on LinkedIn.

Pei gave three reasons for the strict return-to-office mandate. First, he said, the logistics of developing a smartphone, where design, engineering, and manufacturing departments collaborate, weren't conducive to remote working.

He added that creativity and innovation worked better in person, allowing the company to do more with fewer resources.

Third, Pei said Nothing's ambitions to scale to become a "generation-defining company" wouldn't be achievable with remote work.

According to Pei's email, the new mandate will take effect in two months, and he intends to hold a “town hall” in London to answer employees' questions.

In his email, the Nothing CEO also suggested that employees who could not commit to five days in the office look for other employment.

"We know it's not the right type of setup for everybody, and that's okay. We should look for a mutual fit. You should find an environment where you thrive, and we need to find people who want to go the full mile with us in the decades ahead."
