How to Start an Employee Resource Group (ERG) That Actually Works

Apr 9, 2026

Employee Resource Groups (ERGs) can be one of the most powerful ways to build community, improve retention, and support employee growth inside an organisation.

But most ERGs fail before they ever create real impact. They become inactive, poorly attended, or turn into “extra work” for a few committed people.

The problem isn’t the idea — it’s how they’re started.

This guide will show you how to start an ERG that actually works, without overengineering it from day one.


What is an Employee Resource Group (ERG)?


An Employee Resource Group (ERG), sometimes called an affinity group, is a voluntary, employee-led group designed to foster connection, support, and development among employees who share a common identity, background, or interest.

Common examples include:

  • Women in Tech

  • Black Employee Networks

  • LGBTQ+ groups

  • Veterans groups

  • Working Parents communities

ERGs can support:

  • Employee engagement

  • Career development

  • Inclusion and belonging

  • Internal networking


Step-by-Step: How to Start an ERG

1. Define a Clear Purpose

Start with a simple question:

Why does this ERG need to exist?

A strong ERG has:

  • A clear audience (who it’s for)

  • A clear goal (what it helps with)

Example:

“Support career growth and community for early-career women in engineering.”

Avoid vague missions like “create a safe space” without defining what that actually means in practice.


2. Find 1-2 Committed Leaders

One of the biggest mistakes is starting with too many organisers.

Instead:

  • Find 1–2 people who genuinely care

  • Make them responsible for getting things started

You don’t need a committee yet.

You need momentum.


3. Start Small (Don’t Overengineer It)

You do not need:

  • a full strategy

  • a dedicated platform

  • executive sponsorship upfront

To begin, keep it simple:

  • Create a Slack, Teams, or WhatsApp group

  • Plan a first informal meetup

  • Invite a small group of interested people

The goal is to start, not to build the perfect structure.


4. Get Lightweight Leadership Buy-In

Before asking for budget, ask for support.

This could be:

  • Permission to run events during work hours

  • Internal visibility (e.g. company newsletter)

  • A senior sponsor who supports the mission

Keep the ask small and specific.

5. Run Your First 3 Events

Don’t overthink it — just get people together.

Simple ideas:

  • Intro session: why this ERG exists

  • Open discussion: shared experiences or challenges

  • Guest speaker or internal leader

Consistency matters more than perfection.


6. Measure Engagement Early

If you want your ERG to last, you need to show that it’s working.

Start tracking:

  • Number of attendees

  • Repeat participation

  • Feedback from members

This becomes critical when:

  • asking for budget

  • scaling the ERG

  • demonstrating impact to leadership

If you need to justify your ERG internally, using a simple ROI model can help quantify its value (e.g. engagement, retention, participation).


Common Mistakes to Avoid

Most ERGs struggle because of a few predictable issues:

1. Overcomplicating things early

Trying to design everything upfront instead of starting small.

2. Too many organisers

Leads to slow decision-making and lack of ownership.

3. No clear purpose

People don’t engage if they don’t understand the value.

4. Lack of consistency

One or two events aren’t enough to build momentum.

5. No measurement

If you can’t show impact, leadership support will fade.


When Do You Need an ERG Platform?

In the early days, simple tools are enough.

But as your ERG grows (typically 30–50+ members), things become harder to manage:

  • Communication gets fragmented

  • Events become harder to coordinate

  • Engagement becomes difficult to track

This is when a dedicated platform can help by:

  • centralising communication

  • managing events and participation

  • providing visibility into engagement

Final Thoughts

The most successful ERGs don’t start big.

They start simple, build momentum, and evolve over time.

Focus on:

  • clarity of purpose

  • consistent activity

  • real engagement

Everything else can come later.
