Whose Office Is It, Anyway: Generational Warfare in Seoul and London

🇰🇷 South Korea · 🇬🇧 UK

By Priya Mehta, The Global Office

Nearly half of Korean companies surveyed by job portal Saramin reported a "high number" of MZ-generation employees quitting within their first year, while in the UK, HR Magazine found 45% of Gen Z workers sense an active generational divide at work, against just 23% of workers over 50. Both countries are watching their youngest employees renegotiate terms their predecessors simply accepted — but Korea's fight is over an age-based hierarchy so precise it dictates who pours whose drink, while Britain's is a quieter argument about whether being contacted after 6pm is reasonable at all.

South Korea: Age Isn't a Number, It's an Org Chart

Korean workplace hierarchy runs on two parallel systems — job title and Korean age — and expatriates chronically underestimate how literally both are enforced. Even without a formal reporting relationship, someone older than you is your "senior" by social default, a norm strong enough that colleagues routinely ask new hires their age within the first conversations, not as small talk but as a functional need: it determines speech formality and behavioral deference. Layered on top is the corporate title system, where seating, drink-pouring order, and how disagreement gets framed all flow from rank.

The MZ generation — Korea's term for millennials and Gen Z combined, roughly a third of the population in 2026 — is pushing back hard on this system's costs rather than its existence. A 2025 study of over 9,000 employees linked hierarchical culture directly to higher turnover intention among younger workers, and 66.5% of surveyed MZ workers now name work-life balance as the single most important factor in a "decent job." The government has responded structurally: since January 2026, a national subsidy supports 4.5-day workweek adoption at small and medium enterprises. Hoesik, the compulsory after-work dinner-and-drinking ritual, is in particularly steep decline among younger staff, who increasingly treat it as an imposition on personal time rather than a bonding opportunity.

UK: A Quieter, More Values-Driven Fight

Britain's generational tension is less about formal hierarchy — British office structure was never as codified as Korea's — and more about always-on expectations and values alignment. HR Magazine's data shows 86% of Gen Z workers report being contacted outside working hours, and 78% object to it, while boomer managers are the demographic most likely to initiate that contact in the first place. Nearly half of UK workers aged 16 to 34 say they've felt like the "odd one out" at work specifically because of their age.

The values gap is sharper than the hierarchy gap: 51% of Gen Z workers in the UK say they wouldn't accept a job offer from a company that doesn't visibly work on diversity and equity, compared to just 35% of Boomers. Communication style differences compound this — older colleagues favor calls and face-to-face meetings, younger ones default to instant messaging — and research cited by workplace consultancies found employees with managers more than 12 years their senior are 1.5 times more likely to report low productivity, suggesting the friction has real operational costs, not just cultural ones.

The Reckoning

The structural difference is that Korea's generational conflict is fought over an explicit, nameable system — hierarchy encoded into language, seating, and titles — which makes it easier to point at and, paradoxically, easier for younger workers to organize resistance against as a defined target. Britain's version is diffuse: nobody codified the expectation of after-hours availability, so there's no single rule to repeal, just a slow renegotiation of norms company by company. Hofstede Insights scores South Korea considerably higher on power distance (60) than the UK (35), which tracks with the sharper generational visibility in Korean workplaces versus the UK's subtler friction.

What's genuinely surprising is how similar the underlying demand is once you strip away the cultural packaging: both generations of younger workers want the same thing, clearer boundaries between work and life, evaluated more on merit and less on tenure or seniority theater. Korea is getting there through direct confrontation with hierarchy; Britain is getting there through attrition and quiet renegotiation.

The Part the Brochure Left Out

Quora — A respondent explained that even foreign hires in Korea are expected to know their Korean age within the first week, since colleagues genuinely can't calibrate how to speak to you without it — one described being visibly relieved to learn a new hire was younger, simplifying the required speech level immediately.

Internations Seoul — A Canadian marketing manager described being surprised how quickly her seniority, once established, earned her unprompted deference from colleagues a few years older but junior in title — a dynamic she said took months to feel comfortable using.

Ask a Manager — One UK-based commenter wrote about managing a Gen Z hire who requested explicit written expectations for response times outside office hours, calling it initially jarring but ultimately the clearest onboarding conversation they'd had with any new employee in a decade.

teamblind.com — A Korean tech employee who'd worked at both a traditional chaebol and a startup said the real generational fault line wasn't age but company type — the startup's twenty-something founders enforced longer hours than any hoesik-era manager ever had.

r/AskUK (cross-posted discussion referenced in Korea Herald coverage of generational conflict) — A retail team lead in her fifties described feeling blindsided when a 22-year-old report pushed back on being messaged during annual leave, admitting she hadn't questioned that norm in thirty years of working.

Conclusion

If you're moving into either workplace as someone early in your career, the practical lesson is the same even though the systems look nothing alike: figure out where the unwritten rule actually lives — in Korea, that's age and title; in the UK, that's after-hours availability — and decide deliberately how much you're willing to push against it before you've built the standing to do so safely. The honest thing I'd tell a friend heading into either job: the older generation isn't wrong to expect deference, and the younger generation isn't wrong to want boundaries — you're just walking into the middle of a negotiation that started before you got there, so read the room before you say anything.
