“Remote work is no longer acceptable,” thundered Elon Musk in a leaked memo to Tesla staff in late May.

The world’s richest man doubled down when he confirmed the memo’s authenticity on Twitter, writing that remote workers “should pretend to work somewhere else.”

As it turns out, remote workers really are pretending to work quite a lot, but pretending to work is hard work.

New data from Qatalag and GitLab puts a number on it: Knowledge workers waste an extra 67 minutes online each day doing menial tasks for the express purpose of proving to their managers and colleagues that they’re available and working.

It’s taking a strain. The survey polled 2,000 knowledge workers and found that more than half of them (54%) reported feeling pressure to show their online status by replying to emails and Slack messages, adding comments to Google Docs, or updating project management tools.

It’s a new twist in the developing saga of remote work, and it shows that escaping the culture of presenteeism isn’t as simple as escaping the (physical) office.

‘Digital presenteeism’

The report calls this “digital presenteeism.” It’s the remote version of traditional presenteeism, when workers stay at their desk for no reason other than to prove to their bosses they’re working.

Digital presenteeism hinges on that same visibility—whether that means “responding to notifications, or sitting in Zoom meetings you don’t need to attend,” the report says. And, like office presenteeism, it doesn’t correlate to any better work output.

The worries about maintaining active Slack status aren’t unfounded. Many CEOs besides Musk have been vocal about their belief in the superiority of in-person work.

Goldman Sachs CEO David Solomon calls remote work “an aberration,” while remote work is seen as no match for the office when it comes to learning, growth, and creating upward mobility, according to Chris Merrill, CEO of capital market company Harrison Street. “It’s very important to get the younger employees in the office, collaborating and working hard,” he said.
