South Korea survey finds AI cuts work hours by nearly 18%

South Korean workers reported a 17.8% drop in their work hours after using generative AI platforms, according to a poll by the Korea Chamber of Commerce and Industry (KCCI).

The survey of 3,000 employees aged 20 and above found that AI tools helped workers cut an average of 8.4 hours from their weekly workload.

AI adoption was highest in the information and telecommunications sector at 77.6%, with larger companies showing higher usage rate than small and medium-sized firm.

The main use of AI tools was for drafting or summarizing documents.

Non-users cited limited efficiency gains, while employees at large firms pointed to security rules as barriers, prompting experts to call for greater investment in both AI tolls and workforce training.

🧠 Food for thought

Implications, context, and why it matters.

Key details behind the self-reported AI time-savings require a closer look

  • The methodology behind the reported 8.4-hour average weekly reduction should be reviewed, so self-reported time saved is separated from measured productivity gains.
  • The generative AI tools tied to these results should be named, plus how use differs by industry beyond the high adoption in the information and telecommunications industry.
  • The cause of the “low work efficiency” reported by non-users remains uncertain, since it could be driven by the tools, limited employee training, or a poor fit for some roles.

Security rules at large firms may constrain AI adoption, creating an opening for compliant deployments

  • In the poll, non-users at large companies named corporate security regulations as the main reason. That alone does not prove security rules block adoption among current users or that the barrier is “not skepticism about value.”
  • This gap creates room for company-ready AI that fits common security setups, such as on-premise deployment or use inside a firm’s private cloud.
  • Vendors would also need to meet South Korean privacy requirements plus follow guidance from the Personal Information Protection Commission (PIPC), South Korea’s privacy regulator, including its guidance on generative AI development and use (Aug. 2025) 1.
