On May 20.05.20 11 am i received regular duty joining message from my dept HOD . i replied i will join within 5/6 days because i have some financial problem.and also illness of my mother. next i joined duty on 27.05.20. After working 2 hour latter suddenly management person (commercial head) calls me his room and asked why i am absent in lock down period. Next he direct me not to comes to the factory until he recalls me again.. Now from dated 27.05.20 to till date he never call me again and remains silent except sending me one enquiry letter on 10.06.20 and one show cause letter on 16.06.20 about my Absenteeism reason with some unclear point and threaded me for termination.. i replied both the letter. om timely. In the middle no salary credited me for the month of April May and June and i am afraid they will not pay July also. i can't understand what they are want to do? i am working there 13 years as commercial assistance..
