I have given my resignation on 27 May 2021 and it was accepted on 2 June 2021 , I was working till 8 June 2021 , yet I was continuously asked by the team members to report to office inspite of the metro not working and unavailability of the personal vehicle , yet we were made compulsory signed that we had to serve 3 months notice period . But due to ongoing situation of Covid I was not able to commute to the office as it is in other state and even requested to do work from home. The request was denied and I was continuously called and asked to join office back . Due to ongoing pressure and continuous mental stress , I stopped working from 9 June 2021. After 14 days , the HR and the team has asked me to come back and serve the notice period , they are completely denying for work from home and today they have even issued notice for me . I am working as an customer support executive and the sector is Manufacturing sector . I do not have any assets of the firm with me and they have hold my letter of experience along with my salary of 8 days just because of serving the notice period of 3 months by physically being present in the firm . In this situation when government is themselves insisting to do work from home , I am being forced to get to the office physically and serve my notice period . Please help as I am willing to serve notice period nut due want to do the work from home.
