## Meaning

Communication or work that does not require immediate, real-time responses. Team members contribute on their own schedule rather than meeting at the same time.

In tech workplaces, async refers to any work or communication that happens independently of time zones and live interaction. This contrasts with synchronous meetings where everyone participates simultaneously. Async communication includes Slack messages, email threads, recorded video updates, and documentation that team members read and respond to when convenient. It is especially valuable in distributed teams spanning multiple time zones, as it reduces the need for everyone to be online at once. Async work allows engineers to focus on deep, uninterrupted work while still staying connected to their team. Many tech companies now embrace async-first cultures where meetings are the exception, not the rule.

## When you hear it

Our team uses async updates so engineers in Tokyo, London, and San Francisco can work together without constant meetings.

## Examples

- **in a standup:** "Instead of a meeting, we will do an async standup this week where everyone posts updates in Slack."
- **in a code review:** "The code review process is async, so you can leave comments and the author will respond when they're available."
- **in a team meeting:** "Since we have team members across five time zones, we decided to move this discussion async using our internal documentation wiki."

## What native speakers say

- "Let's keep this async to respect everyone's time zones."
- "I prefer async communication for this task."
- "We should handle this async rather than scheduling another meeting."

## Common mistakes

- ✗ "We need to async the problem right now." → ✓ "We should discuss this async instead of calling a meeting." (Async is not a verb meaning to solve something urgently. It describes the mode of communication, not the action itself.)
- ✗ "Can we sync up async tomorrow?" → ✓ "Can we sync up synchronously tomorrow at 10am?" (Sync up and async are opposites. Sync up means to meet in real time, which is the opposite of async.)
- ✗ "This project is too complex for async work." → ✓ "This project requires some synchronous collaboration, though we will use async updates when possible." (Async is not about complexity but about communication style. Most projects benefit from a mix of async and synchronous work.)

## Be careful

Avoid confusing async (asynchronous communication/work) with async (asynchronous programming). Context usually clarifies which meaning is intended.

## FAQ

### What does async mean in tech communication?

Async (short for asynchronous) means communication or work that does not require everyone to be present or respond at the same time. Team members can read, review, and respond when it fits their schedule. This is especially useful for distributed teams across different time zones.

### How do you use async in a work conversation?

You typically use async as an adjective or noun to describe communication channels or work styles. Examples: 'Let us handle this async via email,' 'We prefer async updates in our team,' or 'Can we keep this async to avoid scheduling conflicts?'

### Is async formal or informal?

Async is casual but professional. It is widely used in tech company Slack messages, emails, and meetings. While it started as tech slang, it is now standard vocabulary in the tech industry and appears in job descriptions and company policies.

### What is the difference between async and sync?

Async means asynchronous (non-real-time, people respond when they can), while sync means synchronous (real-time, everyone participates at the same time). A synchronous meeting requires everyone to be online together. An async update lets people respond on their own schedule.

### Why do tech companies emphasize async work?

Async work respects time zones, reduces meeting fatigue, and allows engineers to focus on deep work without constant interruptions. It also creates a written record of decisions, making it easier for new team members to understand project history and context.
