Thanks for the reply.
Sir, CEO & COO called him for discussion in his cabin and that time he said Sorry to me but only for formality purpose and next day most of employee show me their attitude, not talk with me and avoid me.
Without any mistake they want me to feel guilty.
Loud voices n talk about HR if any can be overlooked if it is a stray comment.
It is not HR duty to tell any employee to be less noisy.
The dept Head should tackle such intra dept issues.
Just do your duty in friendly interactive manner
In the first incident of loud talking, your approach was inappropriate.
You should not have directly ticked off an employee as it is the responsibility of the team leader to discipline. You ought to have brought this truant behaviour to his notice and advised him to take an appropriate action.
Second incident is such a trivial that you could have simply ignored it.
I think that person had some internal dispute with you, i don,t know what is that it could be related with work, or else that is why he or she shouted on you. try to ignore these type of person. if he or she taking loudly that effect everyone not only you. everyone should raise their concern regarding their discussion.
Thanks & Regards
