SEOUL, May 4 (Reuters) – South Korean contract drug manufacturer Samsung Biologics estimated a strike by its ​labour union over pay that ‌started late last month has cost the company about 150 billion won ($101.90 million).

The estimate reflected the financial impact from a “partial disruption to overall ‌line ​production,” the company said ⁠in an email ⁠sent to Reuters.

Samsung Biologics added that “the precise financial impact cannot be quantified at this time, as the company is ​continuously applying all applicable measures to minimise impact.”

A total of 2,861 employees, ⁠about half of the ⁠total workforce, have been striking ​since April 28, according to the union’s ​website.

The management offered a 6.2% hike, ‌according to the company. Both sides will resume talks on Monday, Yonhap News Agency reported.

Reuters could not immediately reach ⁠a representative at Samsung Biologics’ union for comment.

The labour dispute could slow Samsung’s efforts to win ⁠new ‌orders and also disrupt a ⁠review into whether to build ​a ‌sixth plant, according to a ​note by ⁠Shinyoung Securities.

Clients, attracted by Samsung’s on-time, low-cost delivery, could turn to rivals in Europe and the United States, the note said.
