Senior doctors at major hospitals in South Korea began submitting their resignations en masse Monday in support of medical interns and residents who have been on a strike for five weeks over the government’s push to sharply increase medical school admissions.

The senior doctors’ action won’t likely cause an immediate worsening of hospital operations in South Korea because they have said they would continue to work even after submitting their resignations. But prospects for an early end to the medical impasse were also dim, as the doctors’ planned action comes after President Yoon Suk Yeol called for talks with doctors while suggesting a possible softening of punitive steps against the striking junior doctors.

About 12,000 interns and medical residentshave faced impending suspensions of their licenses over their refusal to end their strikes, which have caused hundreds of cancelled surgeries and other treatments at their hospitals.
