Industrial action by workers of the South Korean beverage producer Jinro has seen retailers buying in extra bottles of the company's soju, the local media reported today.

Workers at Jinro have begun a work-to-rule action today and retailers fear it may lead to a supply shortage of soju.

The labour action is ahead of a general strike, which 97% of Jinro's unionized workers voted for on Friday. Workers are battling with the company over pay and better working conditions.
One report said that the industrial action could cut Jinro's daily output of its soju brand Chamjinisulro by as much as 20%.
Market sources were quoted saying that retailers were rushing to hoard Jinro's Chamjinisulro.
