IT service units of Samsung, Hyundai Motor and Shinsegae groups have recently seen a string of new unions, according to the paper.

The tech sector's unionization rate has been low, but automation and restructuring fears are changing the mood, analysts say.

Young, developer-heavy workforces are leading the drives, demanding transparent treatment and job security.

Union growth at these affiliates could reshape labor relations and wage bargaining across the conglomerates.

Experts say preemptive safety nets — retraining and redeployment — are key to heading off conflict in the technology transition.
