Anchor Days
Anchor days are designated days when all team members are expected to be in the office simultaneously, creating a structured hybrid model. Research from Stanford shows that fixed anchor days reduce quit rates by roughly 35% with no negative impact on productivity.
Also known as: coordination days, in-office days, structured hybrid days
Why It Matters
Hybrid work without structure underperforms. When employees choose their own in-office days independently, coordination suffers: people come in on different days, miss each other, and the office becomes an expensive place to do the same work they could do from home. Anchor days solve this by concentrating in-person time so that the activities that benefit from co-location (brainstorming, relationship building, complex problem-solving) actually happen when people are together.
What the Research Shows
Nick Bloom's research at Stanford, published in Nature (2024), found that structured hybrid models with fixed anchor days reduce employee quit rates by approximately 35% while showing zero negative impact on productivity, performance reviews, or promotion rates. Critically, unstructured flexibility (where employees choose freely) underperformed the fixed-day model because it produced random, uncoordinated office attendance.
How to Implement Effectively
Effective anchor day design requires intentionality about what happens on those days. The worst outcome is bringing everyone to the office to sit in individual video calls. Anchor days should be structured around activities that genuinely benefit from in-person interaction: collaborative work sessions, team retrospectives, onboarding, mentoring, and social connection.
- Designate two to three fixed days per week when the full team is in-office
- Schedule collaborative and relationship-building activities on anchor days
- Protect remote days for deep focus work and async communication
- Review anchor day effectiveness quarterly and adjust based on team feedback

Async-First Communication
Async-first communication is a team practice where the default mode of sharing information is written and asynchronous, with synchronous meetings reserved for discussions that genuinely require real-time interaction. It prioritizes documentation over conversation.
Meeting Architecture
Meeting architecture is the deliberate design of a team's meeting portfolio: which meetings exist, what each one is for, who attends, and how they connect to each other. It treats meetings as a system to be designed rather than events that accumulate.
Execution Rhythm
An execution rhythm is the recurring cadence of planning, doing, reviewing, and adjusting that a team follows to maintain consistent forward progress. It replaces reactive firefighting with predictable operational cycles.
