A global research and consulting firm that certifies organizations based on employee trust survey results, producing the widely recognized Best Workplaces lists published annually with Fortune and other media partners.
Key Takeaways
Great Place to Work started with a simple question: what makes some workplaces better than others? In 1984, journalist Robert Levering and business writer Milton Moskowitz set out to answer that question for a book project. They visited hundreds of companies, interviewed thousands of employees, and reached a conclusion that still holds: the quality of the relationship between employees and management defines the workplace experience. Trust is the foundation. Everything else builds on it. That insight became the basis for Great Place to Work, the organization they founded in 1992. Today it's the most recognized workplace certification program in the world. The core methodology hasn't changed much. Employees fill out a confidential survey rating their experience. If enough of them say the experience is good, the company earns certification. If the scores are high enough relative to others in the same category, the company appears on a Best Workplaces list. The survey isn't asking "Are you happy?" It's asking specific questions about trust, fairness, and whether management follows through on commitments. That specificity is what gives the certification credibility. A company can't fake its way to GPTW certification because the data comes directly from employees, not from management's self-assessment.
The certification process has two components, and both must meet threshold scores for a company to qualify.
The Trust Index is a 60-statement survey where employees rate their agreement on a five-point scale. Statements cover five dimensions: credibility ("Management is competent at running the business"), respect ("This is a psychologically and emotionally healthy place to work"), fairness ("People here are paid fairly for the work they do"), pride ("I feel I make a difference here"), and camaraderie ("There is a family or team feeling here"). The survey is confidential and administered by GPTW, not the employer. A minimum response rate (typically 60% for companies under 1,000 employees, with adjusted thresholds for larger organizations) is required. To achieve certification, 65% or more of employees must rate the overall experience positively.
Management fills out a Culture Brief detailing the company's people practices, programs, demographics, and policies. This provides context for the survey results and helps GPTW assess whether the organization's practices support the culture employees describe. The Culture Brief covers topics like compensation philosophy, benefits, learning and development programs, diversity initiatives, internal communication methods, and recognition practices. It accounts for roughly 25% of the evaluation for Best Workplaces list placement.
The certification cycle runs year-round. Companies can begin the process at any time by purchasing a subscription (typically starting at $1,000 to $3,000 for small companies and scaling up based on employee count). The survey window usually lasts 2 to 3 weeks. Results arrive within 2 to 4 weeks of survey close. If the company meets the certification threshold, the certification is valid for 12 months. Companies must recertify annually to maintain their status. There's no guarantee of certification. If employee scores fall below the 65% threshold, the company receives the data and feedback but not the certification badge.
The first three dimensions (credibility, respect, fairness) measure the employee's trust in management. The last two (pride and camaraderie) measure the employee's relationship with their work and their colleagues. GPTW's research shows that trust in management is the single strongest predictor of overall workplace satisfaction. Organizations that score well on all five dimensions create what GPTW calls a "For All" experience, meaning the positive experience extends to every demographic group, not just the majority. This equity dimension is increasingly weighted in list rankings.
| Dimension | Core Question | What It Measures | Example Survey Statement |
|---|---|---|---|
| Credibility | Do employees believe management is competent and honest? | Communication quality, competence, integrity | "Management delivers on its promises" |
| Respect | Do employees feel management values them as people? | Professional development support, work-life balance, involvement in decisions | "Management shows a sincere interest in me as a person, not just an employee" |
| Fairness | Do employees feel decisions and opportunities are equitable? | Pay equity, impartiality, justice in promotions and treatment | "People here are paid fairly for the work they do" |
| Pride | Do employees feel proud of their work and their organization? | Individual contribution, team achievement, company reputation | "I feel I make a difference here" |
| Camaraderie | Do employees experience genuine connection with colleagues? | Hospitality, community, team collaboration | "People celebrate special events around here" |
GPTW publishes over 60 Best Workplaces lists annually, segmented by country, company size, industry, and demographic focus.
The most prominent list is Fortune's 100 Best Companies to Work For (US), published since 1998. Other high-profile lists include the World's Best Workplaces (top 25 multinational companies), Best Workplaces for Women, Best Workplaces for Millennials, Best Workplaces in Technology, and country-specific lists in the UK, India, Brazil, Mexico, the Middle East, and dozens of other markets. Each list has its own eligibility criteria based on company size, geographic footprint, and survey scores.
Certification is the first step. Only certified companies are eligible for list consideration. List ranking is determined by a combination of Trust Index scores (approximately 75% weighting) and Culture Brief evaluation (approximately 25% weighting). The exact methodology varies by list. Size categories ensure that a 50-person startup isn't compared directly against a 50,000-person enterprise. Category-specific lists (Technology, Financial Services, Health Care) allow industry-relevant benchmarking.
Being on a Best Workplaces list provides significant employer branding value. Glassdoor data shows that companies appearing on recognized best-workplaces lists see a 20% to 40% increase in application volume in the months following publication. The media coverage, social proof, and third-party validation create credibility that self-promotion can't replicate. Companies typically display the GPTW badge on careers pages, job postings, LinkedIn profiles, and office signage.
Certification delivers measurable returns across recruiting, retention, public reputation, and internal culture.
The GPTW badge signals to candidates that real employees have validated the culture. In a market where 75% of candidates research employer reputation before applying, this third-party endorsement reduces skepticism. Certified companies report higher application volumes, stronger candidate quality, and improved offer acceptance rates. For companies hiring in competitive talent markets (technology, healthcare, finance), the badge provides a meaningful differentiator.
The survey process itself drives improvement. When employees see that leadership takes the survey seriously, shares results transparently, and acts on feedback, engagement increases even before any specific changes are made. GPTW reports that certified companies have voluntary turnover rates 25% to 50% lower than non-certified peers. The certification creates a positive feedback loop: better culture leads to certification, certification motivates continued investment, continued investment improves culture.
GPTW's research, validated by independent studies, shows that companies on the Fortune 100 Best list outperform the stock market by 3.36x over a 25-year period. While correlation doesn't equal causation, the relationship is consistent across industries and time periods. The likely mechanism: high-trust cultures produce more engaged employees, who deliver better customer experiences, which drives revenue and margin growth.
The certification is widely respected, but it has legitimate limitations that organizations should understand before investing.
Companies must purchase a subscription to participate in the certification process. Critics argue this creates a pay-to-play dynamic where only companies willing to spend money can earn the badge. GPTW counters that the fee covers survey administration and analysis, and that certification isn't guaranteed just because you pay. Still, the financial barrier means smaller organizations and nonprofits may be underrepresented among certified companies.
Companies choose when to deploy the survey. A company going through layoffs or a difficult reorganization might delay the survey until morale improves. GPTW requires a minimum response rate to reduce selection bias, but companies can still influence participation through internal promotion campaigns that disproportionately reach engaged employees. The certification reflects a snapshot, not necessarily the year-round experience.
Some employees at certified companies report experiences that don't match the GPTW badge on the careers page. This can happen when results vary significantly across departments: one division may score well enough to pull the overall average above the certification threshold while another division struggles. GPTW has addressed this partially by requiring demographic breakdowns and introducing the "For All" methodology that penalizes organizations with inconsistent experiences across groups.
Certification success requires genuine culture work, not survey optimization. Here's what the preparation process should look like.
