Hundreds of resident doctors of the hospitals attached to medical colleges in Ajmer, Kota and Jodhpur on Wednesday extended their support to over 8,000 in-service doctors who have gone on an indefinite mass leave, as the deadlock between them and the Rajasthan government continued for the third day.While the resident doctors boycotted work for two hours, the medical services in the government hospitals continued to remain crippled. The doctors have placed as many as 33 demands, including the formation of a separate cadre and fixation of new pay grades.Talks inconclusiveTalks between Medical and Health Minister Kali Charan Saraf with the representatives of agitating doctors ended without any result on Tuesday night. Mr. Saraf reviewed the situation of healthcare services and seasonal diseases at a meeting with the Health Department’s senior officers at Swasthya Bhavan here on Wednesday.Mr. Saraf said that contrary to the doctors’ claim of having submitted mass resignations, he had not received any papers. “There is no legal validity of collective resignations. Such an act will only invite disciplinary action,” he said.The Minister affirmed that no doctor had submitted an individual resignation because they knew that it would be accepted. “Our doors are open for talks, but the doctors should not test our patience,” he said, adding that alternative arrangements had been made for treatment of patients in private hospitals.
