Dealing with a Gríma Wormtongue in the workplace

A Modern Tale of Subtle Sabotage

In Tolkien’s The Lord of the Rings, Wormtongue was a manipulative advisor who quietly poisoned the mind of King Théoden, undermining allies and consolidating power through deceit and subtle manipulation. Unfortunately, this archetype of the sly, duplicitous and insidious advisor is not confined to the pages of fantasy novels. In the professional world, the “Workplace Grima Wormtongue” represents those individuals who, through subtle sabotage and covert undermining, disrupt the fabric of a harmonious work environment. Though their insidious nature is obvious to many, unveiling the hidden antagonists among us can seem near impossible. This is made more difficult as it is often the most senior leader’s ear in the organisation that Grima is whispering into.

Recognizing the Signs of a Workplace Wormtongue

A workplace Wormtongue often hides behind a façade of helpfulness and concern while subtly working against others for personal gain. Their tactics are rarely overt, which is what makes them so dangerous. Common behaviors include:

  • Whisper Campaigns: Spreading quiet, seemingly harmless doubts about a colleague’s competence or character in private conversations.
  • Playing Both Sides: Offering different versions of events to different people, often with the goal of sowing discord or confusion.
  • Feigning Concern: Posing as a supportive figure while offering advice that subtly undermines confidence or influence.
  • Feigning Innocence: A key trait of the Workplace Grima Wormtongue is their ability to feign innocence. When confronted, they often deny any wrongdoing and may even play the victim, deflecting blame onto others.
  • Information Gatekeeping: Controlling the flow of information to manipulate outcomes or narratives.
  • Undermining Authority and Colleagues: Making small, insidious comments that, over time, chip away at someone’s credibility.
  • Credit and Blame Manipulation: Seizing opportunities to claim others’ successes while deflecting responsibility for mistakes.

The result is a corrosive environment where trust is compromised and effective collaboration becomes difficult.


How to Handle It: A Strategic Approach

Dealing with a manipulative coworker of this type requires a careful, strategic response. Here’s a step-by-step framework:

1. Document Everything

When facing a Wormtongue-like figure, documentation is your first line of defense. Keep a private, secure record of any incidents, including:

  • Dates, times, and details of interactions.
  • Names of witnesses, if applicable.
  • Copies of emails or written communications.

This not only helps identify patterns but provides evidence should you need to escalate the matter later.


2. Strengthen Direct Relationships

Do not allow this individual to be the sole voice shaping how others perceive you, especially with decision-makers:

  • Maintain regular, transparent communication with leadership and key stakeholders.
  • Ensure your successes and contributions are visible through presentations, status updates, and team meetings.
  • Use factual, professional language to avoid appearing reactionary or defensive.

The goal is to control your own narrative.


3. Build Trusted Alliances

You’re likely not the only one affected. Subtly compare notes with trusted colleagues. A network of allies can validate your experiences, provide emotional support, and collectively dilute the manipulator’s influence.

Approach this carefully to avoid creating an atmosphere of gossip or factionalism — frame your conversations around improving team collaboration and transparency.


4. Set Firm, Professional Boundaries

Where appropriate and safe, address problematic behavior calmly and directly. Focus on facts, avoid emotional escalation, and set clear expectations.

For example:
“I noticed you mentioned I hadn’t submitted the project report, but I sent it on Tuesday. In the future, let’s clarify these points directly before bringing them up in meetings.”

This sends a message that you’re aware of their tactics without giving them ammunition.


5. Escalate if Necessary

If the behavior escalates into harassment, sabotage, or serious professional misconduct:

  • Bring your documented evidence to HR or upper management.
  • Frame the issue around its impact on team productivity, morale, and business outcomes, rather than personal grievances.
  • Maintain a calm, professional demeanor — you’ll be more credible if you’re seen as focused on organizational well-being.

Protecting Your Confidence

Perhaps the most insidious effect of a Wormtongue-like presence is the erosion of self-confidence. They excel at planting seeds of doubt. To counter this:

  • Regularly reflect on your own achievements and capabilities.
  • Seek support from trusted mentors or friends outside the immediate situation.
  • Remind yourself that manipulative tactics often say more about the perpetrator’s insecurity than your own worth.

You have every right to work in an environment free from manipulation and hidden agendas.


The Bigger Picture

While office politics and difficult personalities are inevitable, manipulative figures like a modern Wormtongue don’t last forever. Transparency, integrity, and consistent performance tend to win out over whispered sabotage in the long run. The key is to protect yourself while contributing positively to your team and maintaining your personal and professional values.

If you suspect you’re dealing with a Wormtongue at work, trust your instincts. Stay sharp, stay strategic, and remember — even in Tolkien’s story, the truth eventually came to light.
