What Are Employee Resource Groups — and When Should a Company Start One?

Employee resource groups — or ERGs — give employees a structured way to connect with colleagues who share similar backgrounds, interests, or experiences. For growing companies, they’re one of the more practical tools available to support inclusion, engagement, and retention without a major overhaul of your HR strategy.

But starting an ERG well takes more than good intentions. Without leadership support, clear goals, and some structure, even the most well-meaning efforts can fizzle out before they gain real traction. This guide walks through what ERGs are, why they matter, and how to launch one that actually sticks.

What Is an Employee Resource Group (ERG)?

An employee resource group (ERG) is a voluntary, employee-led group where people with shared identities, backgrounds, or interests come together to connect, support each other, and grow professionally.

Today, ERGs in the workplace can focus on shared identity — such as race, gender, or disability — or shared life experiences, like being a working parent, a veteran, or early in your career. Either way, the purpose is the same: Help people feel like they genuinely belong.

Unlike informal social groups, ERGs typically have leadership and HR support, and may include executive sponsors, defined goals, and a regular calendar of events and meetings.

Common Types of ERGs in the Workplace

The structure and focus of employee resource groups varies by organization, but common examples include:

• ERGs for women in leadership or career development
• Groups supporting Black, Hispanic, Asian, or multicultural employees
• LGBTQ+ employee networks
• Veteran employee groups
• Working parent or caregiver communities
• Remote or hybrid employee groups
• Early-career professional development groups

Ultimately, ERGs help create opportunities for employees to connect, share experiences, and contribute to a more inclusive workplace culture as your organization grows.

Why ERGs Matter for Businesses

Done well, ERGs can strengthen your culture while directly supporting employee engagement, retention, and professional development.

As companies grow, employees want to feel more connected — and they often want ways to contribute beyond their day-to-day work. Well-run ERGs can meet both of those needs, while also supporting company goals like retention, culture, and DEI.

ERGs Help Boost Employee Engagement

One of the most immediate benefits of ERGs in the workplace is how they help employees feel genuinely connected — to their colleagues and to the company.

ERGs often provide:

• Peer mentoring and networking opportunities
• Leadership and volunteer experience
• Career development support
• A stronger sense of belonging
• Opportunities for employees to contribute to workplace initiatives

These experiences can be especially valuable in growing companies where employees may otherwise feel disconnected as teams expand or work remotely or across multiple locations. ERGs can also complement existing employee engagement programs by creating more opportunities for participation, communication, and collaboration across teams.

ERGs Help Strengthen Company Culture

As your business scales, maintaining a consistent, inclusive culture gets harder. That’s where ERGs can make a real difference.

Well-supported ERGs can help reinforce organizational values by encouraging collaboration, respectful communication, and shared participation across departments. They also create opportunities for employees to engage with one another outside their normal workflows.

For many organizations, ERGs contribute to culture-building by:

• Encouraging cross-functional collaboration
• Supporting inclusion and respectful workplace practices
• Helping new employees build connections more quickly
• Supporting internal networking and mentorship
• Creating opportunities for employee feedback and dialogue

ERGs tend to work best when they are integrated into broader workplace strategies rather than operating independently from company culture initiatives.

ERGs Support Diversity and Inclusion Initiatives

Many organizations also use employee resource groups to support diversity and inclusion initiatives in practical ways.

For example, ERGs may help businesses:

• Gather employee feedback on workplace experiences
• Identify gaps in inclusion or communication
• Support recruiting and retention efforts
• Improve onboarding experiences
• Encourage leadership visibility and employee dialogue

For growing companies, these conversations matter more as your team grows, diversifies, and changes.

At the same time, successful ERGs require structure and oversight. Employers should ensure participation remains voluntary, inclusive, and aligned with workplace conduct policies.

When Should a Company Start an ERG?

Not every organization is ready to launch an ERG immediately. While employee resource groups can support engagement and culture-building, they require ongoing participation, leadership support, and operational structure to remain effective over time.

The decision to start an ERG often depends less on employee headcount alone and more on whether your organization is ready, employees show interest, and your company can make a long-term commitment.

Signs Your Organization May Be Ready for an ERG

In many companies, interest in ERGs builds naturally as teams grow and it becomes harder for everyone to stay connected.

Common signs your organization may be ready include:

• Employees are already forming informal networking or support groups
• Teams are becoming more distributed or hybrid
• Leadership wants to strengthen retention and engagement
• Employees are asking for more mentorship or development opportunities
• The organization is expanding its diversity and inclusion initiatives
• Managers are looking for additional ways to strengthen workplace connections

ERGs can also give structure to the culture-building that used to happen naturally in a smaller team — and ensures it still happens as you grow.

Assess Organizational Readiness

Before launching an ERG, take an honest look at whether your company has the capacity and commitment to support it for the long haul.

At this stage, leadership support is especially important. Employees are more likely to participate when they see managers and executives genuinely invested in the ERG’s success — not just nominally supportive.

Key considerations include:

• Leadership buy-in and executive sponsorship
• HR capacity to support oversight and communication
• A workplace culture that encourages respectful participation
• Realistic expectations around employee time commitments
• Resources for meetings, events, or communications

Identify Employee Needs and Interests

The best ERGs in the workplace are built around what employees actually want — not what leadership assumes they need. Before you launch anything, go directly to your people. Gather input through:

• Employee surveys
• Listening sessions
• Engagement discussions
• Retention or culture assessments

These conversations can help you identify where your employees may feel disconnected and which groups would be most meaningful to your workforce. It also helps you avoid building something employees don’t actually want to join.

Secure Resources and Internal Support

Here’s a common pitfall: When ERGs lack organizational support, all the work falls on a handful of dedicated volunteers. That’s a fast track to burnout — and an ERG that quietly fades away.

Even employee-led groups need real support behind the scenes:

• Budget for events or programming
• Communication tools and meeting support
• HR guidance on workplace policies
• Executive sponsors who help increase visibility and participation
• Clear expectations around leadership roles and responsibilities

How to Start an Employee Resource Group

Start small. Rather than launching multiple ERGs at once, begin with one well-supported group and expand as interest grows. Here’s how:

Define the ERG’s Mission and Goals

Start by defining what the ERG is for and what a successful first year looks like. Clear goals help members understand the group’s purpose — and help you track whether it’s working.

This may include goals related to:

• Employee engagement
• Mentorship and development
• Networking opportunities
• Inclusion and workplace connection
• Community outreach or volunteer initiatives

Recruit Leaders and Build Membership

Recruiting the right leaders often determines whether an ERG gains momentum or stalls. Look for employees who are genuinely enthusiastic. To build a strong foundation:

• Identify employee champions or organizers
• Encourage voluntary participation
• Clearly communicate the ERG’s purpose across the organization
• Encourage your managers to support participation

An executive sponsor from leadership makes a real difference. They can advocate for the group, help secure resources, and signal to the rest of the company that this program is worth taking seriously.

Establish Participation Guidelines and Expectations

As your ERG grows, a little more structure goes a long way to keep things fair and consistent for everyone involved. Set clear expectations around:

• Leadership responsibilities
• Time commitments
• Workplace conduct expectations
• Communication standards
• Coordination with HR policies

Always ensure participation is voluntary, inclusive, and aligned with your company’s policies.

Set a Consistent Meeting and Communication Cadence

Regular communication keeps the ERG visible and active. It also helps employees see how the group connects to the company’s broader culture goals.

Depending on your organization, your ERGs should have:

• Monthly meetings
• Internal newsletters or communication channels
• Mentorship or networking events
• Volunteer or educational initiatives

Measure Impact and Gather Feedback

Like any workplace program, ERGs need regular check-ins. Gather feedback, track participation, and adjust as you go. The goal is steady progress, not perfection out of the gate.

Meaningful things to track include:

• Participation and attendance trends
• Employee feedback
• Engagement survey insights
• Retention or development indicators
• Interest in future ERG initiatives

Common Mistakes Companies Make When Launching ERGs

ERGs can be genuinely valuable — and getting the most from them means avoiding some common mistakes, including:

• Launching ERGs without leadership buy-in
• Creating groups without clear goals or direction
• Treating ERGs as symbolic rather than operationally supported
• Overloading employee volunteers without adequate resources
• Launching too many ERGs too quickly
• Failing to communicate the ERG’s purpose across the organization
• Ignoring HR policies or workplace conduct expectations

The through line in all of these? Treat ERGs as real, supported programs — not passion projects left to fend for themselves.

How HR and PEO Support Helps ERGs Scale Sustainably

As your company grows, managing ERGs gets more complex. HR teams must balance engagement goals with workplace policies, manager training, and consistency across teams and locations.

A professional employer organization (PEO) or HR partner can take a lot of that off your plate.

A PEO like G&A Partners can support your business by helping you:

• Align ERGs with broader HR and engagement strategies
• Develop policies and participation guidelines
• Support manager training and internal communication efforts
• Create consistent processes for events and employee participation
• Track engagement trends and program effectiveness with HR technology and survey tools
• Strengthen broader diversity and inclusion initiatives

Well-supported employee resource groups can strengthen connection, support development, and build a more inclusive culture. They work best when leadership is invested, goals are clear, and the program has the support it needs to last.
