Gen Z workers may have a reputation for rejecting traditional workplace norms, but new survey data suggests the opposite is often true: younger job seekers are more likely than older generations to change aspects of their personalities to fit company culture. The findings highlight a growing HR challenge around workplace authenticity, employee experience and the line between adapting professional behavior and asking employees to suppress who they are.
For companies trying to build a strong workplace culture, the question is increasingly less about whether employees should adapt and more about what they are being asked to adapt to.
A new Express Employment Professionals-Harris Poll survey found that 67% of U.S. job seekers have changed aspects of their personality to fit workplace culture, while 63% say their personality at work is substantially different from who they are outside work. The pattern is particularly pronounced among younger workers.
Among Gen Z job seekers, 80% said they have changed their personality to fit workplace culture and 75% said their workplace personality differs from their everyday personality. For millennials, those figures were 69% and 66%, respectively. The rates fell to 59% and 56% for Gen X and 50% and 42% for baby boomers and seniors.
The findings complicate a familiar assumption about younger employees being less willing to conform to established workplace expectations. Instead, Gen Z and millennials appear to be doing more behavioral adjustment than older generations, even as they question whether that adjustment should be necessary.
The survey found that 86% of job seekers consider adapting personality to workplace culture a core professional skill. Another 83% believe employees who cannot or will not adjust may not remain with a company for long.
That creates a difficult balance for HR leaders. Adaptability can be valuable when it means learning how to communicate with different colleagues, respond constructively to feedback or behave appropriately under pressure. But it becomes more problematic when “culture fit” effectively becomes a requirement to behave like everyone else.
The distinction matters because personality is already influencing workplace outcomes. According to the survey, 94% of hiring managers and 91% of job seekers believe personality affects perceptions of performance. Meanwhile, 99% of hiring managers and 90% of job seekers say a positive or approachable personality can accelerate career advancement.
Yet 56% of job seekers say personality has nothing to do with their ability to perform their jobs. The disagreement is particularly strong among Gen Z, with 71% rejecting the idea that personality should be relevant to their work capability.
That tension exposes one of the weaknesses in conventional culture-fit hiring. When organizations evaluate candidates partly on personality, they can unintentionally reward familiarity rather than capability. HR technology platforms that incorporate behavioral assessments, talent analytics or AI-assisted recruiting therefore face a similar challenge: determining which behavioral characteristics genuinely predict job performance without turning subjective preferences into automated hiring criteria.
The issue is also emerging at a time when organizational culture itself is under pressure.
Gartner reported that the percentage of employees likely to recommend their organizations as great places to work fell from 35% in the third quarter of 2022 to 26.5% in the second quarter of 2025. Highly engaged employees also declined from 33.2% to 25.5% over the same period. Gartner found declines in employees’ understanding of, belief in and behavior around organizational culture.
Those numbers suggest that employers cannot treat culture as a one-way process in which employees simply adapt to predefined norms. The culture itself may need to change.
The Express survey provides another indication of that gap: only half of job seekers said their companies provide guidance on managing or developing their personalities for professional settings. Support was more common among younger workers—59% of millennials and 58% of Gen Z respondents—but fell to 39% for Gen X and 30% for older workers.
For HR teams, that points toward a broader employee-experience opportunity. Instead of telling workers to “fit in,” companies can establish clearer expectations around behaviors that matter: respectful communication, collaboration, accountability, feedback and decision-making.
That approach also aligns with a growing debate around authenticity at work. McKinsey recently examined the limitations of the “bring your whole self to work” philosophy, arguing that professional effectiveness requires employees to adjust their behavior to circumstances while remaining aligned with their values.
The distinction is particularly important for hybrid and distributed organizations, where communication styles can have an outsized effect on collaboration. A direct communicator may be effective in one team but perceived as abrasive in another. A highly reserved employee may contribute strongly without exhibiting the outgoing personality traditionally associated with leadership potential.
Technology can help make these differences more visible, but it cannot eliminate the underlying judgment. Employee engagement platforms, people analytics systems and AI-powered HR software can identify patterns in feedback, collaboration and retention, but organizations still have to decide which behaviors they want to reward.
The strongest approach may therefore be to make culture more explicit while making personality less prescriptive.
For employees, that could mean developing the ability to adapt communication and behavior without feeling compelled to construct an entirely different professional identity. For employers, it means separating legitimate behavioral expectations from personal preferences.
The broader lesson for HR technology providers is equally significant. As AI becomes increasingly involved in recruitment, performance management and employee analytics, organizations will need to be careful about encoding subjective ideas of “professionalism” into automated systems.
A healthy workplace does not require everyone to act alike. It requires people with different personalities to work effectively under a shared set of expectations.
Market Landscape
The findings sit within a broader HR technology shift toward employee experience, organizational culture analytics, skills-based hiring and personalized workforce management.
Gartner says organizations that embed culture into employees’ everyday work can see significant improvements in performance and engagement, but only 48% of employees in its research said they feel personally connected to their organization’s values.
That creates room for HR SaaS providers to move beyond employee surveys toward continuous listening, behavioral analytics, manager enablement and personalized learning. However, the increasing use of AI in talent decisions also raises the stakes. Personality assessments and behavioral signals can introduce bias if employers confuse cultural conformity with job capability.
The competitive opportunity is therefore not simply to measure culture, but to help enterprises understand whether their culture enables different types of employees to perform effectively.
