OK
I also agree with some but first do a meeting alongwith the HR, & his / her HOD and that guy and understand the suituation, some time employee going many problums just like ;
1. House problums
2. Family problums in house,
3. Any other problum, like fail in Love, Lost of Memory,
4. Any problums alongwith the subordinate and staff etc.
so, if employee facing any problums and counsile alonwith and clear the issue.
If full team has not found any problums of the guy then issue a advisory letter to non performance and give the stipulated time to the person after that you can issue Stern Warning, after that you can give a chargesheet and then do the domestic inquiry, no body can't terminate the employee without any inquery.
Termination are not a solution, you can give one more chance to from present department to any other department. i think employee may not happy his present work.
HR not a TLWAR, HR means Human, please counsil.
