Answer:
friends name,
As a friend, I am sending this letter to express my concern about your bullying conduct and substandard performance in the department.
We have received multiple reports about your inappropriate conduct with your coworkers. As a manager, you should serve as a source of encouragement for your staff rather than instill dread in them. As a result, their performance has deteriorated significantly over the previous three months, as has yours.
You are aware of ABC Limited's rules and understand that such conduct will not be tolerated. We are sending you a warning letter, which will become a termination letter if your conduct does not improve.
Regards,
your name
