Samsung Electronics' largest union in South Korea warned that chip production could be disrupted if members approve the plan in a strike vote in May. As the world's largest memory chip maker, a strike at Samsung could exacerbate global semiconductor supply bottlenecks. Choi Seung-ho, chairman of the Samsung Electronics Labor Union (SELU), said at the launch of the vote last week: "I expect there will be production disruptions." The vote will continue through Wednesday. Choi Seung-ho said that if labor and management fail to reach an agreement, the union is expected to hold an 18-day strike starting May 21, which could affect about half of the production at the massive semiconductor complex in Pyeongtaek, south of Seoul. The Samsung union is demanding a 7% raise in base pay, the removal of the performance-based compensation cap, currently set at 50% of annual base salary, and the introduction of a bonus pool based on operating profit.
