Dealing with lying and deceitful colleagues can be a challenging situation in the workplace.


It can erode trust, disrupt teamwork, and create a negative atmosphere. Here are some strategies to address this issue.

1. Gather evidence

Before taking any action, make sure you have concrete evidence! This could include email correspondences, records, or firsthand accounts of the lies or deceptive actions. Having evidence is crucial as it will be difficult to address the issue without it.

2. Confront calmly and privately

If you are certain that a colleague is lying, consider having a private and calm conversation with them. Express your concerns without being accusatory. Share the evidence you have gathered and ask for their perspective. Sometimes, people make mistakes or misunderstand situations, and open communication can clear up misunderstandings.

3. Document everything

Keep a record of all interactions with the deceitful colleague, especially if you continue to encounter issues. This documentation can be helpful if you need to involve HR or management in the future. It provides a clear timeline of events and any efforts you’ve made to address the problem.

4. Seek involvement of HR

If the issue persists after your initial conversation, it may be necessary to involve your manager or HR representative, to mediate the situation. They can help address the issue objectively and provide guidance on how to proceed. Follow your company’s policies and procedures for reporting workplace issues.

5. Maintain professionalism

While dealing with a deceitful colleague, always maintain professionalism. Avoid becoming emotional or confrontational. Stick to the facts and focus on finding a resolution to the problem. This approach will help protect your reputation and maintain a positive image in the workplace.

6. Set boundaries

Let your colleague know what behaviour is acceptable and what isn’t. Communicate your expectations for honesty and cooperation. Having clear boundaries can prevent future deceitful actions.

7. Build allies

It’s helpful to build positive relationships with other colleagues and supervisors. Having allies can offer support and potentially put pressure on the deceitful colleague to change their behavior. Share your concerns with trusted coworkers or supervisors who can provide advice and assistance.

8. Know when to escalate

If all else fails and the behaviour continues, you may need to escalate the matter to higher management or, if necessary, seek legal advice. Be aware of your company’s policies and your rights in such situations.
