<human>:  How can I deal with a difficult co-worker effectively?
<bot>: One way to effectively deal with a difficult co-worker is to stay focused on the task at hand and maintain a professional demeanor. Instead of getting into a conflict, strive to understand their perspective and work towards finding a resolution. Communicate your concerns in an assertive yet respectful manner and avoid making assumptions. Also, take a break when necessary and remind yourself to stay calm and respond thoughtfully. Finally, if the situation does not improve seek help from a supervisor or manager to assist in resolving it.
