The Kakao Bank union announced a strike on the 31st due to issues with the performance-based reward system. Key issues include annual salary increase rates, and it is analyzed that the recent demand for strengthening performance-based rewards spreading in the IT industry is behind this. Kakao Bank plans to maintain core services through emergency support personnel, and service disruptions are expected to be limited. This strike could be the first case since the launch of internet-only banks, and there is still a possibility of last-minute negotiations between labor and management. Ultimately, if the strike takes place, it could lead to wider discussions about the compensation system for internet banks.
