How to Make Async Communication Inclusive for Non-Native English Speakers

Async communication has become the backbone of remote work. Written discussions, Slack messages, GitHub comments, and shared documents replace the instant feedback of office life. For teams spread across continents, this shift offers flexibility—but it also creates barriers for team members who communicate in English as a second or third language.

If you write async communication that assumes native-level English fluency, you’re excluding talented teammates and losing their contributions. This guide shows you how to write async messages that work for everyone on your team, regardless of their language background.

The Problem with English-Centric Async Communication

When you type quickly during a busy workday, you likely use idioms, slang, and complex sentence structures without thinking. Phrases like “circle back,” “deep dive,” or “low-hanging fruit” make perfect sense to native speakers but create confusion for others. Compound sentences with multiple clauses, passive voice, and implicit context all increase cognitive load.

Consider this typical Slack message:

“Hey team, can we touch base on the API refactor? I think we’re kinda barking up the wrong tree with the current approach. Maybe we should table this and revisit after the sprint demo?”

This message contains three idioms (“touch base,” “barking up the wrong tree,” “table this”) and assumes the reader knows the sprint schedule. For a non-native speaker, parsing this takes significantly more effort than for a fluent speaker.

Writing Clear Async Messages

The core principle is simple: write for clarity first, brevity second. Clear communication actually takes less time to produce because it reduces follow-up questions and misunderstandings.

Use Simple, Direct Language

Replace idioms with plain language. Instead of:

“Let’s circle back on this after standup”

Write:

“Let’s discuss this after our daily standup meeting”

Instead of abstract expressions, use concrete verbs. “Table this” becomes “postpone this.” “Bark up the wrong tree” becomes “take the wrong approach.”

Break Up Complex Information

Long paragraphs with multiple ideas are harder to process. Group related points together and use bullet lists:

Instead of:

“The new authentication system needs to be implemented by next Thursday and it should handle OAuth2 flows for Google and GitHub, plus we need to support JWT tokens for mobile clients and I think we should also consider adding rate limiting because of the API security concerns everyone has been talking about.”

Write:

“The new authentication system has these requirements:

  • Implement OAuth2 for Google and GitHub
  • Support JWT tokens for mobile clients
  • Add rate limiting for API security
  • Complete by next Thursday”

Provide Explicit Context

Non-native speakers often struggle with implied context. Include information that native speakers would infer:

Weak: “Check the PR for details.”

Strong: “I’ve opened PR #247 that implements the user dashboard. Please review the changes by Wednesday so we can merge before the release. The main changes are in dashboard.js and api-routes.js.”

Code Examples and Technical Writing

For developer teams, technical communication carries additional complexity. Code examples, error messages, and technical discussions need special attention.

Use Descriptive Variable and Function Names

Bad code creates confusion even for native speakers, but it disproportionately affects non-native developers:

// Confusing
function process(data) {
  return data.filter(x => x.active).map(x => x.val);
}

// Clear
function getActiveUserIds(users) {
  return users
    .filter(user => user.isActive)
    .map(user => user.id);
}

Write Meaningful Commit Messages

Generic commit messages force reviewers to dig through code to understand changes. Good commit messages follow a consistent format and explain the “why”:

# Weak
"fix bug"

# Better
"Fix race condition in user authentication flow

The previous implementation checked auth state before each request
but didn't handle concurrent requests properly. This caused intermittent
login failures when users submitted forms quickly after page load.

Fixes #142"

Document Edge Cases Explicitly

When writing technical documentation, spell out scenarios that native speakers might infer:

## API Rate Limiting

The API allows 100 requests per minute per API key.

Edge cases:
- If a client exceeds the limit, they receive HTTP 429
- The rate limit resets at the start of each minute
- Failed requests (4xx/5xx) still count toward the limit
- There's no burst allowance—clients must space requests evenly

Tools That Help

Several tools can help your team write more inclusive async communication:

Building Inclusive Async Habits

Making async communication inclusive requires ongoing attention, not one-time fixes. Start by auditing your recent written communications:

  1. Count idioms and slang terms
  2. Measure average sentence length
  3. Check for implicit context (assumed knowledge)
  4. Identify technical jargon without explanations

Then pick one improvement to focus on for two weeks. Small changes compound—using clear language consistently will improve comprehension for everyone on your team, native speakers included.

The goal isn’t to dumb down your communication. It’s to remove unnecessary barriers that have nothing to do with intelligence or capability. When you write async messages that work for non-native English speakers, you build a more inclusive team where everyone can contribute their best ideas.
