Office is forcing to get quarantine inside office premises in order to work

I'm a Central Govt Employee. My office is forcing us to get quarantine inside office premises and work from there. We ask them to call us on daily basis but they refuse to do so. We reported at office on 11 May 2020 and quarantined for next 14 days. After 14 days we were allowed to come to office for work. Conditions there were extremely pathetic and we faced lot of difficulties like food, water, unhygienic washrooms etc. Even no safety measures were adhered as issued by Ministry of Health & Family Welfare. We were forced to live under such conditions and situations becomes worse when our quarantine was over. I spent there 33 days and many of my colleagues are still stuck there. Authorities are not sanctioning their leave. The place is more like Concentration Camps and we were harassed mentally every single day. Huge disparity is going on as many employees in our office are coming on daily basis. When we questions to authorities no response received from their end. Our dept is planning again to make us quarantine and constantly threatens & harrassing us to cease our payroll in case we refuse to Quarantine
