The Office Language Gap: Gen Z vs. Millennial and Gen X Bosses

Learning how to "speak office" once required sitting in an office, watching how a boss crafted an email, noticing when a colleague shifted from a quick chat to a formal request, or deciphering phrases like "run it up the flagpole." That era of informal apprenticeship has largely vanished. Gen Z entered a workforce where much of that learning happens through a screen, and the language on either side of that screen often fails to translate.
Workplace communication has always been about more than just vocabulary. It carries unwritten rules: how to address someone, what belongs in an email versus a Slack message, and how familiar to be with a new coworker. The pandemic and the shift to remote work upended the traditional ways Gen Z absorbed these norms. Social media and instant messaging brought different habits into the office, and AI has "entered the chat" as another tool for learning—or for producing awkwardly templated messages.
The generational language divide goes deeper than whether boomers understand "delulu." The words themselves are evolving, but so are the underlying rules about what sounds appropriate or professional. Gen Z brings terms like "rizz" and "no cap" to work; older workers counter with "blue-sky thinking," "move the needle," and the baffling "boil the ocean." These differences are now so pronounced that Sunny Workplace, a nonprofit employee engagement platform, launched WorkGen Translation, an online tool that decodes slang and jargon across age groups. The company commissioned Censuswide to survey 2,004 U.S. workers on May 25 and 26, split evenly between Gen Z and boomers. Among the 1,002 Gen Z respondents, 80% said generational language differences posed a challenge. Only 30% of the 1,002 boomers agreed. The confusion runs both ways: 76% of boomers had no idea what "delulu" meant, 66% did not know "rizz," and 61% were unfamiliar with "no cap." Meanwhile, only 22% of Gen Z knew exactly what it meant to "boil the ocean," and 25% understood "blue-sky thinking."
Yet the most consequential misunderstandings are often mundane. Betsy Sneller, an assistant professor of sociolinguistics at Michigan State University, pointed to email. "Younger folks entering the workforce don't really have the genre of email in the way that older speakers do," she told Fortune. Older workers treat email as a formal, permanent record, while using platforms like Microsoft Teams for quick exchanges. Younger workers, raised on social media and messaging apps, may not draw that line. They skip formal greetings or punctuation, which can come across as rude to older colleagues. "There can be sort of miscommunication where younger folks are being casual in an email, maybe not using punctuation, maybe not using a formal salutation, and it gets interpreted as very rude by older speakers," Sneller said.
Linguists call this a register mismatch. Renée Blake, an associate professor of linguistics and social and cultural analysis at New York University, explained that people shift their language based on context and audience. Work, home, and social settings each have their own expected register. When students email her with "Hey, Renée" instead of "Good morning, Professor Blake," she sees a collision of expectations. "Am I your friend? I'm not your friend, and you don't know me," Blake said with a laugh. The issue is not that one way is correct and another wrong, but that breaking the expected register can feel like breaking the rules of the space. That can lead to unfair judgments about a person's professionalism.
Iain Smith, head of behavioral science at Sunny Workplace, warned that younger workers who have not yet learned the workplace vernacular risk being judged harshly. "If they speak using phrases like 'delulu' and 'rizz,' for instance, I think there are judgments that can be made about professionalism based on that," he said. He noted that today's rookies no longer sit next to a veteran who shares shortcuts and coping strategies. "They're turning up to Zoom."
The pandemic did not just affect Gen Z. "COVID also stunted all of us," Blake said. "It's not just young people." Workers across generations suddenly communicated from behind screens, and many returned only partially. Blake herself experienced confusion when she moved a class online and tried a more informal tone, only to have students push back: "This is too much, this is too informal. You don't know me." She added, "So this is going the opposite direction."
AI is now part of the negotiation. Blake sees young people using it to learn formal professional communication, but the output can feel stiff and impersonal. Despite these challenges, research suggests generational differences are often overhyped. A meta-analysis in the Journal of Organizational Behavior found few systematic, meaningful differences across generations in workplace outcomes. Smith, a millennial, recalled when his own generation was predicted to ruin the workplace. "From a scientific perspective, there's a lot of research out there that shows that actually generational differences in work values, work-life balance, stress, burnout, working preferences are all overhyped," he said.
Still, Sneller believes the communication styles between new entrants and seasoned workers are more pronounced than in the past, thanks to social media and the pandemic. She sees it in her classroom, where students need more encouragement to talk casually. And the line between the generation that needs translating and the one doing the translating shifts quickly. Sunny's survey asked about Gen Alpha slang: 41% of Gen Z did not know what "Ohio" meant, and 75% did not fully understand or would not use "skibidi." Gen Z may not have to wait until middle age to wonder what the kids are saying—they may just have to wait for Gen Alpha to clock in.
Article commentary
The generational language divide in the workplace is a vivid illustration of how rapidly changing communication norms can create friction, yet it also reveals deeper truths about organizational culture and adaptation. At first glance, the survey from Sunny Workplace seems to confirm a popular narrative: Gen Z, raised on TikTok and instant messaging, struggles to adopt the formal registers that older generations expect. But the data also shows that boomers are equally baffled by younger slang, and both sides feel the pain. The real story is not about who is right or wrong, but about the shifting foundations of professional communication itself. What makes this divide particularly sticky is that it is not just about vocabulary. The underlying rules—when to use email versus chat, how to structure a salutation, whether to use punctuation—are learned through immersion, not instruction. Remote work has stripped away the informal mentorship that once happened naturally. New hires no longer observe a senior colleague drafting a carefully worded email or catching a subtle cue about tone. Instead, they inherit a fragmented set of norms from digital platforms, where informality is the default. The result is a collision of registers that can feel personal, even when it is not intended that way. Linguists like Betsy Sneller and Renée Blake rightly point out that the issue is not a failure of younger workers, but a mismatch of expectations. Older workers may interpret a missing salutation as a sign of disrespect, while younger workers may see it as efficient. Neither is inherently wrong, but the gap can have real consequences. Iain Smith's observation about judgments of professionalism is telling: in a competitive job market, small communication missteps can compound into larger perceptions of competence. This is especially risky for early-career employees who are still building their reputations. Yet the narrative of a generational war is overblown. The meta-analysis in the Journal of Organizational Behavior reminds us that work values and preferences are not as generationally distinct as stereotypes suggest. Millennials were once the target of similar critiques, and now they are the bosses complaining about Gen Z. The irony is not lost on Smith, who recalls his own cohort being branded as entitled and disloyal. The real constant is change itself: every generation brings new communication habits, and every generation struggles to adapt to those of the next. What is different today is the pace of change. Social media, instant messaging, and AI are accelerating the evolution of workplace language faster than ever before. The pandemic acted as a catalyst, forcing millions to communicate through screens and blurring the boundaries between formal and informal registers. As Renée Blake noted, even she misjudged the appropriate tone with her own students. The learning curve applies to everyone, not just the youngest workers. Perhaps the most valuable takeaway is the need for explicit communication training and mutual understanding. Companies can no longer assume that employees will absorb the unwritten rules organically. Providing clear guidelines on email etiquette, meeting norms, and channel selection can reduce friction. At the same time, older workers can benefit from recognizing that informality is not necessarily disrespect; it is often just a different register. The rise of tools like WorkGen Translation is a sign that the market is responding to this need, but translation is a stopgap. The real solution lies in fostering a culture where workers of all ages feel comfortable asking for clarification and where differences are seen as opportunities for growth rather than reasons for judgment. In the end, the language gap is a mirror reflecting broader changes in how we work. It challenges us to rethink what professionalism means in an era of hybrid work, digital natives, and AI assistants. The generations will continue to borrow from each other, just as millennials now use "no cap" and boomers adopt "LOL." The key is to keep the conversation going—not to translate, but to understand.
