Though Samsung Biologics and its labor union, which previously failed to reach an agreement despite government mediation, have decided to return to direct negotiations, signs are emerging that the dispute could become prolonged as their legal battle intensifies, with the police investigating allegations that the union chair leaked trade secrets.

The union, management and government recently concluded their tripartite talks, after which the union delivered its revised wage negotiation proposal directly to the company. Samsung Biologics is reviewing the proposal and has until early next week to prepare a response.

However, negotiations are expected to remain difficult, as the two sides remain divided on issues such as wage increases and performance bonuses for employees, as well as management-related demands. Earlier this month, the union staged the first strike in the company’s history and is continuing a work-to-rule campaign by refusing to work overtime and on holidays.
