At some of the world’s most admired companies, employees are encouraged to do something surprising: spend part of their time not doing what they were hired to do.

Google calls it "20% time."3M had a version of it in the 1940s.At Atlassian, it’s known as "ShipIt Days."

The idea is simple but radical: carve out space for employees to pursue passion projects, test unproven ideas, or explore curiosity-driven solutions - without needing permission, and without being judged by immediate ROI.

This approach, often condensed into what many now call the 10% Rule, has quietly fueled some of the most impactful innovations of the last century.

So why does it work? And what can companies learn from it?

Letting Go to Speed Up

Innovation rarely arrives on command. It doesn’t appear neatly during scheduled brainstorms or quarterly roadmapping sessions. It emerges in the in-between moments - where curiosity collides with freedom.

When companies grant employees a slice of time to explore, they're not losing productivity. They're betting on long-term acceleration. Think of it as strategic drift: giving ideas room to move sideways so that they can leap forward.

This is how Gmail was born. How Post-it Notes came to exist. How Google Maps evolved. None of these breakthroughs were assigned. They were discovered.

The Power of Off-Track Thinking

In most workplaces, focus is revered. Goals, OKRs, deadlines - all designed to narrow attention. But there’s a cost to relentless direction: it can flatten creativity.

The 10% Rule creates a sanctioned space for wandering. It legitimizes the question, "What if we tried something completely different?"

This kind of thinking doesn’t just lead to novel products. It leads to smarter systems, better workflows, deeper engagement.

And often, it leads to insights that would never surface inside the lanes of the job description.

Micro-Risk, Macro-Reward

Many leaders hesitate to adopt something like the 10% Rule because it seems inefficient. Time is money. Resources are finite.

But consider the risk in reverse. What’s the cost of not innovating? Of employee disengagement? Of ideas lost because no one had space to test them?

Letting someone spend four hours a week on a new idea is not a risk. It’s insurance. You might not hit gold every time. But over the long arc, small bets yield outsized returns.

Permission Structures Matter

One reason many innovation programs fail? Employees don’t believe they really have permission.

Policies say "go explore," but culture whispers, "stick to your role."

To make the 10% Rule real, companies must:

• Protect that time (don’t schedule over it)
• Celebrate—not penalize—unfinished ideas
• Include curiosity and initiative in performance reviews
• Create forums for sharing passion projects

It’s not enough to offer freedom. You have to back it up with structure and signal.

Passion Builds Resilience

There’s a hidden benefit to giving people creative freedom: it reignites energy.

In burnout-prone industries, letting employees work on projects that excite them - even if those projects aren’t directly billable - boosts morale, retention, and loyalty.

When people feel like they’re allowed to dream inside their job, they stop fantasizing about leaving it.

Innovation at the Edges

Some of the most valuable company insights come from places no one is watching. A data analyst might prototype a better internal dashboard. A junior marketer might test a micro-campaign that outperforms the big one. A customer support agent might spot a user pain point that no one in product noticed.

The 10% Rule isn’t about letting engineers build cool side apps. It’s about recognizing that brilliance lives across the org chart - if you give it room to speak.

Not a Perk. A Mindset.

What separates innovative companies from the rest isn’t just talent or budget. It’s posture.

The 10% Rule isn’t a hack or a perk. It’s a philosophy: that growth comes from decentralizing creativity. That the best ideas are often bottom-up. That trust precedes invention.

Companies that internalize this don’t just get better products. They get better people.

People who feel heard. People who feel challenged. People who stay.

Final Thought: Give Genius Room

We tend to mythologize innovation as a lightning strike. But most innovation is weather. It builds slowly. It gathers.

When companies give people the time and psychological safety to chase curiosity, they aren’t stepping away from business. They’re stepping into the future.

All it takes is a small carve-out. Ten percent of the week. A few hours. A door left ajar.

Because when you give genius room, it tends to show up.
