Samsung Electronics Co Ltd board chairman Lee Sang-hoon (above) was sentenced to 1-1/2 years jail on Tuesday for sabotaging legitimate union activities, a South Korean court said.

Lee and about 25 other defendants were charged with sabotaging union activities by subcontracted workers at Samsung Electronics’ repair unit, Samsung Electronics Service Co Ltd.

When union activities took place at Samsung Electronics Service in 2013, Samsung Group’s now-defunct elite strategy office developed and implemented strategies to hinder the union’s operation, Seoul Central District Court ruled.

Samsung executives and employees were, to different degrees, involved in finding out information about union members to convince them to leave the union, inducing the closure of subcontracting firms with active unions and delaying negotiations between labour and management.

Samsung Electronics declined to comment.

“This is a further signal of change for the South Korean judicial system, which previously gave lenient sentences to convicted businessmen,” said Park Sang-in, a professor at Seoul National University.

Samsung’s new leader, Jay Y. Lee, needed to “build industrial relations which are in line with global standards,” he added.

The verdict follows last week’s ruling by the same court that gave a 16-month jail term to Samsung Electronics vice-president Kang Kyung-hoon on charges of union-busting activities at a different Samsung affiliate.
