Rakesh Malhotra, founder of Five Global Values and author of "Adventures of Tornado Kid: Whirling Back Home Towards Timeless Values” said being accused of being the bully can be difficult to accept.
You may believe your actions were unintentional, or a justified emotional response to provocation. Perhaps, you see yourself as the only one in the office qualified to do anything right. However, whatever you have said or done, whether purposefully or not, you have created a culture of negativity for at least one person and you need to honestly assess the situation and your role in it.
Are you a workplace bully?
Here is one symptom that indicates you could be:
Undermining another employee's work by creating a hostile environment or perhaps by consistently calling their attention to "flaws". (Bullies focus on a person, while constructive criticism focuses on a task.)
