Overview
If someone is critical about your work or your attitude today, don't waste any time worrying about it. Unless they are saying things that will negatively affect your reputation and how others see you, you don't need to give a darn about what they think. But if you do start seeing that people might be listening to this person and believing what they say, then you must address the attacker immediately. People will think that if you don't fight back then what they are hearing must be true.
