In this thread you have posted that:
“He works in a NBFC who is a commercial establishment, standing orders are applicable.
He joined the company 3 months back on a managerial grade.”
If standing orders are certified (CO) and his designation is covered then you may check the notice period stated in standing orders……………………….and if his designation is not covered then look into Model Standing orders Sec13-18……………………..and also the def. of ‘Workman’ as in ID Act and if he is covered then notice period is NIL if he is under probation period and max.30 days if he is confirmed.............................and also the (Name of the state) Shops and Commercial establishments Act and if he is covered by the def. of 'Employee' as in this Act then thi Act shall givern the service conditions including notice period.
