My monitor died mid-sentence at 5:01 p.m. last Friday — not a crash, but South Korea’s biggest banks enforcing a new “4.9-day workweek”: Friday hours cut by one hour, from 6 p.m. to 5 p.m., with full pay unchanged. It’s spreading bank by bank in 2026, unevenly.
I work in the IT division of one of the banks rolling this out — not behind a teller counter, but in the back office that keeps online banking running. That gave me a front-row seat to watching six different banks handle the same idea in six different ways — including one that voted its own pay deal down twice and still ended up running the shorter Friday anyway.

What the “4.9-Day Workweek” Actually Changes
The name is a bit of branding: the 4.9-day workweek (주 4.9일제, ju 4.9-ilje, roughly “the 4.9-day-per-week system”) isn’t a fourth day off. It’s a nod to trimming a sliver off the traditional five-day week rather than adding an actual extra rest day. In practice, it means one specific thing at the banks that have adopted it: on Fridays, staff finish at 5 p.m. instead of 6 p.m., and their salary doesn’t change to reflect the shorter day. No pay cut, no makeup hours quietly added to Thursday.
What makes it real instead of a memo nobody follows is the enforcement mechanism, not the policy language. That’s the part most coverage skips, and it’s also the part that actually shapes a Friday evening for someone sitting where I sit.
If the Counter Still Closes at the Same Time, Who’s Covering the Gap?
Here’s the operational wrinkle that gets flattened in most reporting on this: Korean bank teller windows have run roughly 9 a.m. to 4 p.m. for as long as I can remember, and that hasn’t moved an inch. Customers walking in on a Friday afternoon see the exact same hours they saw last month. The hour that’s disappearing belongs to the stretch after the counter closes — the block from late afternoon into early evening when branch staff handle paperwork, loan processing, and the kind of admin work that used to run until 6 p.m. The 4.9-day workweek shaves an hour off that second, back-half stretch, not the customer-facing one.
The tool that makes this stick is what everyone here calls the “PC-off” system (PC오프제, PC-opeuje, an automatic, company-enforced shutdown of office computers at a set time). It’s not new — Korean companies have used timed shutdowns for years to cap unpaid overtime — but banks repurposed the same switch for Friday afternoons. At 5 p.m. sharp, the machines log everyone out. You can’t quietly keep working through it even if you wanted to, which is either the whole point or the whole controversy, depending on who you ask.

How Korea’s 6 Biggest Banks Compare
On February 1, 2026, it was reported that Shinhan, Hana, and NH Nonghyup had reached agreement on the 4.9-day workweek, bundled with a roughly 3% wage increase and bonuses reported as high as 350% of base pay for Shinhan staff. Woori was still negotiating, and KB Kookmin — whose own tentative deal had already been voted down by its union two weeks earlier — was back at the table. Read as a headline, it still sounded close to a clean sweep. Six months into 2026, the picture is messier than either the headline or the early setback suggested — four banks running the shorter Friday on staggered timelines, one running a different schedule entirely, and one bank that split its own deal into two separate fights.

| Bank | Approach | Timeline | Branch hours | Status (Aug 2026) |
|---|---|---|---|---|
| NH Nonghyup Bank | Friday only, 6→5 p.m. | Effective March 27, 2026 | Unchanged | Running weekly — first mover |
| Woori Bank | Friday only, 6→5 p.m. | Effective May 8, 2026, after new union leadership took office | Unchanged | Running weekly |
| Shinhan Bank | Friday only, 6→5 p.m. | Effective April 1, 2026 | Unchanged | Running weekly |
| Hana Bank | Friday only, 6→5 p.m. | Effective April 17, 2026 | Unchanged | Running weekly |
| IBK (Industrial Bank of Korea) | Wednesday and Friday, 1 hour each | Formal rollout since Jan 7, 2026 (after a 4-week pilot in Dec 2025) | Customer teller hours unchanged, 9 a.m.–4 p.m. (staff shift runs 9 a.m.–6 p.m.) | Running; saved hours converted into job training instead of extra pay |
| KB Kookmin Bank | Friday, 6→5 p.m. — implemented separately from the wage talks | Early-leave running since March 6, 2026 (self-implemented Feb 27); wage/bonus package still unresolved | Unchanged | Early-leave: running. Wage package: rejected twice (Jan 19, Feb 11) — still in negotiation |
KB Kookmin is still the strangest case of the six, just not for the reason it looked like in January. Its first tentative package — a profit-sharing bonus worth 300% of monthly base salary, with roughly half of that paid out in company stock rather than cash, a separate special incentive of ₩6 million, and base-pay raises of 3.1% for general staff and 3.3% for contract staff, on top of adopting the shorter Friday — went to a union vote and was rejected: 5,567 of 9,006 members who cast ballots, or 61.8%, voted no. Reporting at the time pointed to a specific grievance: Shinhan’s own deal, struck around the same time, paid its 350% bonus entirely in cash — worse odds for KB staff by direct comparison. Management revised the offer; it failed a second vote in mid-February, and the wage-and-bonus fight is still unresolved as of August.
What gets lost if you stop reading at “rejected twice” is what KB did next: it pulled the Friday early-leave piece out of the stalled wage negotiation and ran with it on its own, self-implementing the shorter Friday starting February 27 and making it official policy on March 6 — with the employer group publicly confirming the early-leave hour was separate from the wage package, not contingent on it. So the accurate read on KB isn’t “the one bank that said no.” It’s the one bank where employees are already leaving an hour early every Friday while still fighting over how much they get paid for the rest of the week.
Why Is This Happening Now? Korea’s OECD Working-Hours Target
The policy push behind all of this traces to President Lee Jae-myung’s stated goal of bringing Korea’s annual working hours down to roughly the OECD average — about 1,700 hours a year — by 2030. The 1,879-hour figure often cited for Korea’s “current” hours is a few years stale; the newest full-year data, 2025’s tally released in July 2026, puts Korea at 1,833 hours a year — about 96 to 100 hours above the current OECD average, not the roughly 180-hour gap the older number implied. Spread that gap over 8-hour days and it’s still about 12 extra workdays a year — roughly two and a half 40-hour weeks — beyond the OECD norm. One shaved Friday hour, roughly 50 hours a year for someone who works every Friday, now closes closer to half that gap, not a quarter of it. It’s a meaningful dent, not a finish line, and banks are the visible test case because their labor unions are strong enough to actually negotiate this into a contract instead of waiting for legislation.
What Actually Changed on My Side of the Building
I wrote before about what it’s actually like landing in tech inside a Korean financial company in the first place; this is the update to that story. My job description didn’t change, but my Friday did. I checked my badge-swipe log out of curiosity after the third week of this — every Friday exit for the past three weeks is stamped within four minutes of 5:00 p.m., where the same log used to cluster around 6:10 to 6:20. That’s not a subjective impression; it’s what the timestamps say.
What I’ve also noticed is that this doesn’t land the same way for everyone in the building. Back-office and IT staff like me used to be the ones still at our desks after the counter closed, so the PC-off cutoff is the first real change to our week. Colleagues who work the teller counter were already walking out closer to 4 p.m. on a normal day; for them, this policy barely moves the needle, because their hours were never built around the 5-to-6 window in the first place. My own Friday commute shows the same split in miniature — the train I used to catch around 6:10 was standing-room only, and the one I catch now, closer to 5:15, usually has open seats. I’m not convinced that’s “work-life balance” arriving so much as one specific slice of the workforce finally getting an hour that other departments already had.

Frequently Asked Questions About Korea’s 4.9-Day Workweek
Does the 4.9-day workweek apply to every bank employee in Korea?
Not evenly, but it’s closer to sector-wide than it looked in the winter. As of August 2026, NH Nonghyup, Woori, Shinhan, and Hana are all running the shorter Friday on their own timelines, IBK is running a Wednesday-and-Friday version, and even KB Kookmin — whose wage-and-bonus package has now been voted down twice — has been running the early-leave hour on its own since March 6, independent of that stalled pay fight. It hasn’t been adopted industry-wide beyond banking, and it doesn’t extend automatically to other sectors.
Is Korea’s “4.9-day workweek” the same as a “4.5-day workweek”?
No, and the naming trips people up. A genuine 4.5-day or four-day workweek means a full or half day off entirely. The 4.9-day workweek is narrower: employees still work all five days, just with one hour trimmed off a single Friday, at unchanged pay. It’s an incremental schedule tweak, not a shorter week in the way the phrase implies to a foreign ear.
Could this expand to other days or become permanent?
Possibly, but slowly. IBK is already running a version that touches both Wednesday and Friday rather than Friday alone, which shows some appetite for going further. The government’s 2030 OECD working-hours target keeps the broader pressure alive across sectors. But as of now, this remains a finance-sector experiment running at different speeds bank by bank, not a fixed national standard.
Take it from someone whose Friday actually changed: this is a real hour, not a symbolic one, but it isn’t yet the shorter Korean workweek the headlines make it sound like. It’s uneven by design — one bank pulled the schedule change out of a stalled pay fight and ran with it anyway, another is trading the hour for job training instead of extra pay, and the people at the counter mostly won’t notice a thing. I’d watch how KB’s wage negotiation lands before calling any of this settled — the extra hour turned out to be the easy part; the money is what’s still stuck.
