Unionized workers of the Seoul subway system ended their strike at 6 p.m. on the second day of their collective walkout, just before the Friday evening commute. 

The union of Seoul Metro has warned that this week’s strike was a precursor and that there is the possibility of a large-scale strike after next Thursday unless the management is willing to scrap its plans to reduce workforce by some two-thousand. 

The two-day strike, which started at 9 a.m. on Thursday, saw the operation rate of trains hover at around 80 percent of normal levels. 

On the first day of the strike on Thursday, trains were operating at 75-point-four percent of normal levels as of 6 p.m.
