Unionized workers at internet-only Kakao Bank vote to launch a full-scale strike on July 31, the bank’s labor union says. The union says talks with management over wage increases and other benefits have stalled and failed to narrow differences. Negotiations between the union and Kakao Bank’s management have focused on pay and benefits, but the sides do not reach agreement. The dispute comes as Kakao Bank reports strong financial performance earlier this year: in the first quarter, it posts operating income of 211 billion won on revenue of 1.94 trillion won, both described as quarterly highs. The report also links the situation to broader labor tensions within Kakao’s corporate group. Kakao Corp., the parent company, is also described as being in a labor dispute, with wage negotiations between management and labor deadlocked for the past two months. Unionized workers at Kakao Bank previously stage partial and limited actions, including a partial strike in early June and a full-day strike on June 29.
