This is in addition to what Bhaskar has said. You need to give a little more information. My questions are as below:
- Are you from Government Service, PSU, or Private Sector?
- Since when has the employee had "poor" performance?
- What efforts did you take to improve his performance?
- How is the performance appraisal conducted?
- Do you have a formal PMS well in place?
- What kind of training did you provide to improve his performance?
- If the performance was poor, then why is he continuing in the current position? Why was he not sacked? At least, why was he not demoted?
- For how many years has he been slogging in the current designation?
- Did you try placing him in another department?
Does this person have some connection with the labor union? Does management want to keep this person in good humor because he is close to some very senior person from management?
Though information is not complete, I have a feeling that the person has gotten into the groove. Now, when you brought a sudden change, he is resisting it to the hilt. Hitherto, he enjoyed his stasis, and now this displacement has irritated him.
Stickiness to the position is human nature. Notwithstanding poor performance, if our ministers stick to their chairs, then why not this ordinary mortal? Certain ministries are identified with certain persons. Persons are rewarded with ministries due to political considerations. Now, in your case, first confirm what were the considerations that led to this situation, then we will discuss further.
Last Comments: By the way, before uploading a post, you could have checked how other members have written their posts. If you had done that, you would have observed the basic anomaly of writing the entire post in block capital letters. Hope you are aware that writing SMS, email, or posts on social media in block capital letters is against business etiquette. If not, then please take this opportunity to educate yourself.
Thanks,
