An employee resource group is a voluntary, employee-led group organized around a shared identity or experience, and its career value is visibility. At large US employers, most now operate women's ERGs, a practice documented in the McKinsey and LeanIn.Org Women in the Workplace series, which has tracked ERGs as a standard part of corporate diversity infrastructure for years. For an individual woman, a well-run ERG offers cross-functional exposure, leadership practice, and a channel to senior executives that a job description does not. A poorly run one offers lunch-and-learns.
This guide covers what ERGs can and cannot do, and how to use membership deliberately. It is general career information, not a comment on any specific employer.
What is an ERG and who runs it?
ERGs are internal, voluntary, and usually sanctioned by the employer, which distinguishes them from informal coworker groups. A typical structure has an executive sponsor from senior leadership, a chair or co-chairs who do the operational work, and working committees for events, recruitment, or professional development. The federal government formally supports similar groups across its agencies as a workplace practice, and large companies have adopted the same model. The critical detail for a career: the group's budget and its charter come from management, so an ERG's priorities tend to track what leadership will fund.
What can a women's ERG actually give a career?
Three things, in rough order of value.
- Cross-functional visibility. ERG events put junior employees in front of executives they would otherwise meet once a year, and organizing an event demonstrates execution skills to that same audience.
- Leadership practice. Chairing a committee, managing a budget, or running a mentoring program inside the ERG is real management experience, usable in promotion cases, particularly for individual contributors whose day jobs offer none.
- Information flow. ERGs circulate openings, reorganization news, and navigation advice faster than formal channels, which matters for women deciding whether to raise a hand for a stretch role.
What ERGs rarely provide is the decisive promotion mechanism, sponsorship. Advocacy in promotion rooms is a separate transaction, and treating an ERG membership as a substitute confuses community with capital.
What is the time cost and how do you protect against it?
The cost is real and unevenly distributed. ERG leadership roles are mostly unpaid labor on top of a full job, and research on workplace programs, including work compiled by Catalyst on employee networks, has noted that this invisible labor often lands on the same women the groups exist to support. A practical rule is to treat the ERG like any other assignment: negotiate scope before accepting a chair role, ask whether the time is recognized in performance reviews, and set a fixed term. If the answer on recognition is no, take a bounded contribution, one event, one mentoring cycle, rather than a leadership title.

How do you turn ERG membership into a promotion case?
- Pick a role with a countable output: attendees, budget managed, mentoring pairs matched.
- Attach it to a business result the company already cares about, such as retention, referral hiring, or internal mobility.
- Record the outcome while it is fresh, in the same language used for project reviews.
- Use the executive sponsor as a named reference in the promotion narrative, after they have seen the work, not before.
When is an ERG not worth the time?
When it has no budget, no executive sponsor who attends, and no influence on anything the company measures. A group that only convenes will consume evenings without returning anything. Test it early: ask the chair what the group changed in the past year and who signed off on it. A credible answer names a policy, a program, or a pipeline result. An evasive one is information too.
What should employers fix?
Pay the labor and measure the output. Companies that count ERG leadership in performance reviews and fund the groups through business budgets, rather than leftover discretionary spend, get functioning pipelines instead of programming. The Women in the Workplace series has repeatedly found that employees who feel their organization's diversity efforts are genuine are more engaged, and visible, resourced ERGs are one of the easier signals to make genuine. The group is infrastructure. Funded, it builds careers; unfunded, it burns the spare hours of the people it represents.
How do you start an ERG when your company doesn't have one?
With a proposal, not a petition. The successful playbook at companies that built women's groups from the ground up runs in four steps. First, check the policy: many employers have a charter template or an HR process for employee groups, and forming inside it is faster than forming around it. Second, write a one-page business case naming what the company gets, retention, internal mobility, community presence, because the budget will be approved by someone evaluating the group as an investment, not as a favor. Third, recruit one executive sponsor with actual authority over budget or headcount, whose name on the charter is what separates a sanctioned group from a book club. Fourth, launch small and countable: one mentoring cycle or one skills series with attendance recorded, so the second funding conversation happens with data instead of enthusiasm. Members who build the group hold founding titles, and founding an ERG is itself a leadership record, but the same scope rule applies as for running one: fixed term, negotiated hours, and a succession plan from the start.
