Dark Psychology at Work: Manipulation Tactics Used by Bosses and Colleagues

Why work is a common setting

Power differences, competition for promotion and dependence on a salary make it costly to push back at work. Research links workplace manipulation particularly to Machiavellian traits, one part of the dark triad. Most colleagues are not manipulative, but knowing the patterns helps you respond early.

Common manipulation tactics at work

• Taking credit: presenting your idea in a meeting as theirs, or leaving your name off a report.
• Moving goalposts: criteria for success change after you meet them.
• Gaslighting about instructions: "I never asked for that" after a verbal request. See gaslighting examples.
• Guilt-driven overtime: "We're a family here", "I thought you were committed."
• Triangulation: vague reports that "others" are unhappy with you, or pitting team members against each other.
• Information control: leaving you out of emails or meetings, then criticising you for not knowing.
• Public criticism, private praise (or the reverse) to keep you uncertain.
• Weaponised feedback: criticism with no specifics, so you can never fix it.

Examples in messages

• "Just a heads-up, a few people mentioned your attitude in the meeting. I won't say who."
• "I'm disappointed. I expected more initiative from someone at your level." (without saying what was missing)
• "Can you just handle this tonight? I'd hate for leadership to think we're not committed."

How to protect yourself professionally

• Put it in writing: after verbal instructions, send a short summary: "To confirm, you'd like X by Friday."
• Keep a work log of your contributions and key decisions.
• Ask for specifics: "Which part of the report needs more initiative?"
• Share ideas in writing first so authorship is clear.
• Decline politely: "I can't take this on tonight. I can start first thing tomorrow."
• Build allies outside the manipulator's influence.
• Use formal routes (HR, an ombudsperson, a union) when patterns continue.

Manipulation between colleagues

Not all workplace manipulation comes from above. Colleagues may flatter you to offload work, "forget" to pass on information that would help you, take advantage of your helpfulness, or quietly undermine you with small comments to a manager. A practical rule: be generous with help, but make sure your contributions are visible, for example by sharing work in team channels rather than only in private messages.

When the manipulator is a client

Clients can also use pressure tactics: unrealistic deadlines framed as emergencies, scope creep ("just one more small change"), guilt ("we thought you were a partner, not a vendor"), or threats to leave a bad review. Clear written agreements, change-request processes and calm, factual replies are your best protection. Our Check Message tool helps make sure your replies sound professional rather than defensive.

Signs a workplace is becoming toxic

• People are afraid to speak up in meetings.
• Information is used as a weapon rather than shared.
• Credit goes up the chain while blame goes down.
• Rules apply differently to different people.
• Turnover is high, and leavers are badmouthed.

If several of these are true, protecting your health and your record may matter more than changing the culture alone.

Workplace bullying vs a tough manager

A demanding manager sets high standards and is clear about them. Manipulation shows up as inconsistency, hidden criteria, public humiliation and punishment for raising concerns. If your health is suffering, it is reasonable to prioritise leaving a toxic environment over winning it.
