This blog breaks down Rohit Sakunia’s 7 types of toxic coworkers, explains why they’re harmful, and provides science-backed strategies to handle them without losing your sanity.

The Science Behind Workplace Toxicity

• Toxic coworkers increase stress hormones (cortisol) by 30% (Stanford Study).
• Prolonged exposure reduces cognitive function (University of Montreal Research).
• Teams with toxic members are 50% less productive (Gallup Workplace Report).

Now, let’s dissect the 7 toxic archetypes and how to neutralize their impact.

1. The Gossip King/Queen

Why They’re Toxic:

• Gossip erodes trust and creates a culture of paranoia.
• Neuroscience shows gossip triggers the brain’s threat response (amygdala activation).

How to Handle Them:
✅ Avoid engaging – Say, “Let’s focus on the project.”
✅ Redirect to facts – “Do we have data on that?”

Real-Life Example:
A manager at Amazon reduced team conflict by banning gossip in meetings.

2. The Eternal Pessimist

Why They’re Toxic:

• Negativity is contagious—our brains mirror others’ emotions (mirror neuron research).
• Chronic complainers lower team morale by 40% (Journal of Applied Psychology).

How to Handle Them:
✅ Counter with solutions – “What’s one thing we can improve?”
✅ Set boundaries – Limit 1:1 time with them.

6. The Slack Master

Why They’re Toxic:

• Free-riding reduces team motivation (Social Loafing Theory).
