The labor-management conflict within the local bank industry over the expansion of a performance-based salary system is escalating as the labor union of the financial union voted unanimously to go on a general strike.

The Korean Financial Industry Union said Wednesday that it held votes a day earlier on the plan to stage a general strike at around ten-thousand workplaces of the member companies across the country.

Over 95 percent of union members voted in favor of the plan.

The union said the general strike is scheduled to be held in September. 

It is mainly to protest the growing efforts by the local banks to introduce a performance-based wage system, for which the Korea Federation of Banks recently announced a draft guideline.

The Korean Financial Industry Union is led by the labor unions of 19 local banks. 

Currently, seven out of nine state-run financial institutions adopted the performance-based salary system.
