SEOUL, South Korea >> As South Korea’s government made a last plea for junior doctors to end a walkout hours before a Thursday deadline, many were expected to defy orders to return to work, risking suspensions of medical licenses and prosecution.

Thousands of medical interns and residents have been on strike for about 10 days to protest the government’s push to boost medical school enrollments. Government officials have warned that strikers would face legal repercussions if they don’t return to their hospitals by Thursday.

As of Wednesday night, about 9,076 of the country’s 13,000 medical interns and residents were confirmed to have left their hospitals after submitting resignations, according to the Health Ministry. It said 294 strikers had returned to work.

There was no word on any others going back to their jobs as of 10 p.m. (1300 GMT) Thursday.

Observers say many strikers are likely to defy the deadline, continuing the work boycott for weeks or months. The government is expected to begin formal steps toward penalties on Monday, as Friday is a national holiday.

“We’ve said that we won’t hold them responsible for leaving their worksites if they return by today,” Vice Health Minister Park Min-soo told a briefing. “Doctors are there to serve patients, and those patients are anxiously waiting for you. This isn’t the way to protest against the government.”

Later Thursday, Park met some striking doctors for more than three hours, but there were no reports of a breakthrough. Officials invited 94 representatives of the strikers to the meeting, but Park said less than 10 showed up and they were ordinary strikers, not leaders. Park said they asked him about the government’s recruitment plan and he called for them to end their walkouts.

Ryu Ok Hada, one of the striking doctors, told reporters that he wouldn’t attend the meeting. He accused the government of treating the striking junior doctors “like criminals and inflicting humiliation on them.”

Starting March 4, the government will notify doctors who miss the deadline that it plans to suspend their licenses and will give them opportunities to respond, senior Health Ministry official Kim Chung-hwan said.

Under South Korean law, the government can order doctors back to work if it sees grave risks to public health. Those who refuse to abide by such orders can have their medical licenses suspended for up to one year and also face up to three years in prison or a 30 million won (roughly $22,500) fine. Those who receive prison sentences would be stripped of their medical licenses.

Some observers say authorities will probably punish only leaders of the strike to avoid further straining hospital operations.

At the center of the dispute is a government plan to admit 2,000 more applicants to medical schools starting next year, a two-thirds increase from the current 3,058. The government says it aims to add up to 10,000 new doctors by 2035 to cope with the country’s fast-aging population. Officials say South Korea’s doctor-to-population ratio is one of the lowest among industrialized countries.

But many doctors reject the plan, arguing that universities aren’t ready to provide quality education to that many new students. They also say the government plan would also fail to address chronic shortage of doctors in essential but low-paying specialties like pediatrics and emergency departments.

But their critics say the striking junior doctors simply worry about expected lower income because of the sharply increased number of fellow doctors. The government’s plan is broadly popular with the South Korean public, according to a poll.
