The Myth of the Lifetime Job: Loyalty and Mobility in South Korea and the UK

🇰🇷 South Korea · 🇬🇧 UK

By Priya Mehta, The Global Office

South Korea, a country famous internationally for a "lifetime employment" ethos, actually posts the lowest average job tenure in the entire OECD — 5.9 years and falling since the shock of the 1997-98 financial crisis broke the old contract. The UK, with its reputation for individualist career-hopping, sees the average professional switch jobs roughly every 2.6 years, and two-thirds of those switchers leave their occupation entirely, not just their employer. The stereotypes, in other words, have quietly swapped places while nobody was updating the brochure.

South Korea: The Lifetime Job That Isn't

The cultural image of Korean employment — decades of loyal service to one conglomerate, retirement dinners, seniority-based promotion — describes a system that largely stopped functioning after the 1997-98 Asian financial crisis forced mass restructuring and normalized layoffs at companies that had never conducted them before. What replaced it is more fragmented than either the old myth or most Western assumptions suggest: OECD data puts average job tenure in South Korea at just 5.9 years, the lowest figure among member countries, and workers aged 55 to 79 leaving their longest-held job now do so, on average, at 53.

What persists from the old system isn't job security so much as its cultural vocabulary — hierarchy, deference, and internal relationship-building remain central to how advancement actually happens, even as the guarantee of a lifetime position has eroded. The labour market has also split more visibly into secure, benefit-entitled permanent roles, concentrated disproportionately at large chaebol conglomerates, and a much more precarious tier of non-standard contract work with lower wages and fewer protections — a split that matters enormously for a foreign hire evaluating any specific offer.

UK: Mobility as the Rational Default

British career mobility has become genuinely structural rather than merely cultural preference. ONS figures cited by Indeed's Hiring Lab put job switching at around 2.4 percent of the workforce monthly between 2022 and mid-2025, with the average professional now changing jobs roughly every 31.5 months across an average career of about three jobs. The more striking figure is what those switches represent: roughly 63 percent of job changes involve moving into a different occupation entirely, not simply a new employer within the same field — suggesting UK career mobility functions as much as career reinvention as it does simple job-hopping.

The pattern skews sharply by age and sector. Some 45 percent of workers aged 18 to 24 report actively planning a job switch, against just 25 percent of those 55 to 64, while turnover concentrates heavily in sectors like food service and logistics (around 3.2 percent monthly) versus far more stable fields like nursing and electrical engineering (1.6 to 1.8 percent). Hofstede Insights' high UK individualism score, 89, tracks with a culture where career self-authorship is the expected posture rather than an act of disloyalty.

The Reckoning

The genuine surprise here is how thoroughly the two countries have inverted their reputations. South Korea's collectivist cultural values — Hofstede scores it at just 18 on individualism against the UK's 89 — would predict long, loyal tenures, and yet its actual average tenure is the shortest in the OECD, hollowed out by a structural shock three decades ago that the cultural mythology never fully caught up with. The UK's individualist reputation would predict restless job-hopping, and the data bears that out numerically, but the more interesting finding is that most of that movement is occupational reinvention, a far more deliberate and structural form of mobility than "job-hopping" as a phrase implies.

The practical lesson for a foreign hire: don't evaluate job security in either country by reputation. In Korea, ask specifically about the tier your role sits in — chaebol-permanent or precarious non-standard — since that split matters more than any national tenure average. In the UK, don't read a varied CV as a red flag on either side of the interview table; the data says it's simply how careers work there now.

The Part the Brochure Left Out

Quora — Someone debating whether to job-hop in a UK tech career said the calculus had fully flipped from their parents' generation — staying put out of loyalty was starting to look riskier for long-term pay growth than moving every few years, since internal raises consistently lagged what a new employer would offer on day one.

teamblind.com — A thread titled "why you should job hop" drew significant engagement from Korea-adjacent tech workers, with one recurring theme being that younger employees increasingly saw the old loyalty narrative as something companies invoked selectively — expected from staff during downturns, forgotten by management during the same downturns' layoffs.

Reddit — Someone who spent six years in Korean corporate culture before moving to a US company described the adjustment as almost a full personality change — the humility, deference, and indirect communication that had been essential for advancement in Korea were, they found, actively counterproductive in an American office that rewarded direct self-advocacy instead.

Reddit — A UK professional reflecting on two full career pivots by their mid-thirties said the biggest misconception outsiders had was that this reflected instability — in their circle, staying in one occupation for a full decade was the unusual choice, not the reassuring one.

Conclusion

If job security is what's driving your decision between these two, look past the national reputation entirely. South Korea's loyalty mythology no longer matches its tenure data, so ask pointed questions about which tier of the labour market — permanent chaebol role or precarious contract — your specific offer actually sits in. The UK's mobility, meanwhile, is less chaotic than it looks from outside; it's a population methodically reinventing careers, not simply restless. If a friend asked which country to trust with a decade-long plan, I'd say neither, honestly — plan in three-to-six-year increments in both, and let the data, not the stereotype, tell you when it's time to move.
