8 Tips for Dealing with a know it all Co-Worker


  In today's dynamic workplace, many encounter the classic "know-it-all" colleague or superior—those who believe they possess the answer to every question and solution to every problem. Here's a deep dive into understanding this persona and effective strategies to coexist productively.

Understanding the Workplace Know-it-all

The office know-it-all is not an unfamiliar character. They appear in almost every workspace, parading their supposed vast knowledge and often overshadowing others' voices. Career expert Nancy Collamer, author of "Second-Act Careers," elucidates that such individuals dominate conversations, dismissing others’ insights, which can dampen team spirit and potentially harm client relationships.

Andrew G. Rosen, the mind behind Jobacle.com, adds that their poor listening skills and preemptive opinions make collaboration a challenge. Michael Kerr, author of "The Humor Advantage," notes that their habit of speaking more than listening can stifle creativity and innovation.


Strategies for Handling the Know-it-all at Work

  1. Empathy is Key: Rosen emphasizes that a know-it-all's demeanour could stem from deeper personal issues or insecurity. Approach them with understanding rather than irritation.

  2. Choose When to Engage: Collamer advises deflecting rather than investing energy in every conversation. A simple acknowledgment can sometimes be the best response.

  3. Leading with Vulnerability: Kerr believes in the power of admitting, "I don't know." It promotes openness and encourages a collaborative spirit.

  4. Equip Yourself with Knowledge: When presenting or discussing, have your facts straight. As Collamer suggests, come prepared, reducing the chance for the know-it-all to dominate.

  5. Maintain a Light-hearted Approach: Instead of sarcasm, use humour as a buffer. As Kerr suggests, a playful remark can diffuse tension.

  6. Ask Detailed Questions: Push for the why and where behind their assertions. Over time, they may become more circumspect in their declarations.

  7. Private Constructive Feedback: Sometimes, a private, gentle confrontation can make a difference, notes Collamer. Balanced feedback, praising their knowledge but highlighting their overshadowing demeanour, can be useful.

  8. Seek Managerial Intervention Judiciously: Only involve superiors if the behaviour severely impacts your productivity or team cohesion.


Final Thoughts

The know-it-all colleague is a workplace reality. With strategic approaches, it's possible to foster a balanced environment that values everyone's contribution.
