Kakao Corp. (035720.KS), the operator of Korea's near-universal messaging platform KakaoTalk, heads into a second and final mediation session on Wednesday, May 27, with the Gyeonggi Regional Labor Relations Commission (Korea's provincial labor mediation body). If the talks collapse, employees at the parent company would gain the legal right to stage the first walkout in Kakao's history, joining four affiliates — Kakao Pay (Kakao's fintech arm), Kakao Enterprise (its B2B cloud unit), DK Techin (its IT services subsidiary), and XL Games (its game development studio) — that already cleared mediation, according to Seoul Economic Daily.
Wage negotiations between Kakao management and the Kakao chapter of the Korean Federation of Chemical, Textile and Food Workers' Unions (per Seoul Economic Daily) broke down on May 18, per the Korea Times, and the union has since said it is weighing strikes, work-to-rule campaigns, and slowdowns.
What is actually at stake
KakaoTalk serves 45.6 million users in a country of roughly 52 million, per Tech Times, and provides the login backbone for Kakao Pay, Kakao T (ride-hailing) and Kakao Map. The last time the platform went down — an October 2022 fire at its Pangyo data center — KakaoTalk was offline for more than 11 hours, 134 connected services were disrupted, the co-CEO resigned, and then-President Yoon Suk-yeol publicly described the app as "no different from the national communication network," per Tech Times.
This dispute is narrower in scope. The union has signaled that delays in AI development — including Kakao's in-house "Kanana" model — and the rollout of messaging, commerce, content, and finance products are the most likely casualties of a walkout, according to Seoul Economic Daily, rather than messenger uptime itself. The 2022 outage was infrastructure-driven, not staffing-driven, which leaves the live-traffic impact of an office-based stoppage an open question in the cited coverage.
The math behind the bonus demand
The union is asking for performance bonuses equal to 13–15% of operating profit, per Tech Times and Seoul Economic Daily. (The Korea Times reports the demand as 13–14%.) Against Kakao's roughly ₩440 billion ($321 million) in 2025 operating profit cited by Tech Times, the demand translates to roughly ₩57–66 billion ($42–48 million), or about ₩15 million ($10,950) per employee across a headcount near 4,000.
That is a fraction of the SK hynix (Korea's second-largest memory chipmaker) precedent the union is invoking: Tech Times reports SK hynix's 10%-of-operating-profit formula in 2025 produced average payouts above ₩100 million ($73,000) per employee. The Kakao union argues management diverted gains to senior staff, citing "short-term performance bonuses of up to 150%" for executives while the rank-and-file pool shrank, per Seoul Economic Daily.
A wider Korean bonus revolt
Kakao is the third major Korean employer this season to push a fixed profit-share formula. Samsung Electronics' (005930.KS) union is seeking 15% of chip-division profit, Hyundai Motor's union is demanding 30% of net profit, and LG Uplus (Korea's third-largest mobile carrier) is asking for 30% of operating profit plus an 8% base raise, per Tech Times. The common thread: unions want a contractual link to results rather than discretionary management awards.
The equity backdrop
Kakao shares opened 2026 near ₩62,100 ($45.33) and have since fallen roughly 35%, hovering in the low ₩40,000 ($29) range, according to Seoul Economic Daily. The bonus demand alone, if granted in full, would absorb roughly 13–15% of last year's operating profit on the math above.
Historical precedent for actual stoppages at Kakao is thin: Seoul Economic Daily notes Kakao headquarters has never staged a strike since founding, while Kakao Mobility ran a partial two-hour walkout last June.
What to watch
The May 27 mediation outcome is binary. A settlement keeps Kakao Corp. headquarters out of strike status; failure unlocks the legal right to walk. The four affiliates can already strike at any time, per Seoul Economic Daily, so partial actions in fintech, cloud, or gaming units could surface before any headquarters decision. The immediate marker for whether the union escalates will be the post-mediation statement on Wednesday evening Seoul time.
