The government took measures to counter the protesting doctors by serving them with suspension letters and asking them to vacate the hostels to make way for newly recruited doctors. Some states invoked the "Essential Services Maintenance Act" (ESMA) and gave notices to the doctors to return to work, failing which legal action would be taken against them. The government also put on alert 6,000 men from the Rapid Action Force to take care of any untoward incident. However, in most places the protesters remained defiant despite ESMA. Most forward caste students across India took to the streets, boycotting classes. In Delhi, a human chain rally was organized on 20 May by the students of IIT Delhi with the support of PanIIT, the IIT alumni organisation, to protest the OBC reservation. Nearly 150 students of New Delhi's 5 Medical Colleges went on a 'relay' hunger strike in AIIMS which lasted for about a month.
