Patrick Diogenia Analysis of 604,000+ Glassdoor Reviews Finds Employee Voice Can Reveal What Ratings Miss

Historical differences between employers, including Salesforce and McDonald’s, raise a new question about employer-brand resilience

PHILADELPHIA, PA, UNITED STATES, August 28, 2026 /EINPresswire.com/ -- Five workplace ratings may look like five distinct measures of employee experience, but they can sometimes be telling much the same story, according to a new analysis of 604,320 public Glassdoor employee reviews by marketing strategist and graduate researcher Patrick Diogenia.

Diogenia’s newly published research guide, Glassdoor Employee Reviews: What They Reveal About Employee Voice and Employer Brand, examines structured workplace ratings alongside employees’ written descriptions of what they liked and disliked about their employers.

One finding was particularly striking: ratings for senior management, culture and values, career opportunities, compensation and benefits, and work-life balance overlapped so substantially that combining them into a single overall workplace-evaluation measure produced virtually no loss in predictive performance.

“Five scores on a dashboard can create the impression of five independent diagnoses,” Diogenia said. “But sometimes they may be different expressions of a broader judgment about the employer.”

Employees’ own words added information the ratings failed to capture. In the analysis, language describing the negative aspects of work was more informative than positive commentary in distinguishing whether an employee would recommend the organization. Negative recommendations also tended to use sharper, more specific language, while employees who still recommended their employer often described shortcomings in more qualified terms.

The analysis also found meaningful variation across employers in the strength of the association between negative employee commentary and reviewers' recommendations of the company. Across the firms examined, some appeared relatively less sensitive to changes in negative employee voice, while others appeared more sensitive. Salesforce (NYSE: CRM) and McDonald’s (NYSE: MCD) illustrate opposite ends of that continuum: in the historical dataset, negative employee commentary had a weaker relationship with recommendation at Salesforce and a stronger relationship at McDonald’s.

Diogenia cautions that the comparison is not a ranking of the companies, a measure of current employee experience, or evidence that one employer has a stronger brand than the other. Instead, it raises a broader business question:

“Why does negative employee voice appear to carry greater consequences for some employer brands than for others?”

One possible explanation, Diogenia proposes, is employer-brand resilience — the possibility that accumulated trust, familiarity, or reputational strength gives some employers greater capacity to absorb negative employee experiences without seeing the same relationship with advocacy. The current project did not directly measure brand resilience, making it a hypothesis for Diogenia's future research on employee voice. The underlying guide likewise treats the company-level differences as exploratory rather than an employer ranking.

The findings also have implications for employee Net Promoter Score and other listening programs. Diogenia argues that recommendation metrics can provide a useful overall pulse, but should be combined with richer employee voice and other organizational evidence rather than treated as a complete diagnosis.

“Organizations do not have a shortage of employee metrics,” Diogenia said. “The risk comes when a dashboard creates more certainty than the underlying evidence deserves. A score can tell you something moved; employee voice can reveal what employees believe is actually happening. Measuring the workforce is not the same as understanding it.”
