Jerks at Work

Toxic Coworkers and What to Do About Them

A practical and hilarious guide to getting difficult people off your back, for anyone pulling their hair out over an irritating colleague who’s not technically breaking any rules

From open floor plans and Zoom calls to Slack channels, the workplace has changed a lot over the years. But there’s one thing that never changes: you’ll always encounter jerks. Jerks at Work is the definitive guide to dealing with — and ultimately breaking free from — the overbearing bosses, irritating coworkers, and all-around difficult people who make work and life miserable.

Social psychologist Tessa West has spent years leveraging science to help people solve interpersonal conflicts in the workplace. What she discovered is that most of our go-to tactics don’t work because they fail to address the specific motivations that drive bad behavior. In this book, she takes you on a rollicking deep dive of the seven jerks you’re most likely to encounter at the office, drawing on decades of original research to expose their inner workings and weak points — and ultimately deliver an effective game plan for stopping each type before they take you down with them.

You never know when a jerk is going to get in the way of your success, but with Jerks at Work you can finally protect yourself. This book is career insurance!”

Vanessa Van Edwards, author of Captivate

This book provides the key to working smarter, better, and happier, no matter who you’re working with.”

Jerks at Work is packed with everyday examples and clever strategies, such as how to:

  • Stop a Bulldozer from gaining influence by making sure they’re not the first to speak up in meetings
  • Report a Kiss Up/​Kick Downer to a manager who idolizes them without looking like the bad guy
  • Protect your high-achieving team from Free Riders without stifling collaboration
  • Use a Gaslighter’s tactics to beat them at their own game

For anyone who’s said ​“I can’t stand that jerk!” more times than they’d like to admit, Jerks at Work is the ultimate playbook you wish you didn’t need but will always turn to.

Praise for Jerks at Work

West’s book follows in the footsteps of Stanford University professor Robert Sutton’s runaway bestseller, The No A**hole Rule, and its hands-on sequel, The A**hole Survival Guide. A social psychologist at New York University, West categorizes different kinds of toxic coworkers (the kiss up/​kick downer,” free rider” and gaslighter,” to name a few) and describes how best to engage with them. Even if you don’t have to encounter them in person, difficult colleagues still pervade remote work and can be just as hard to manage in the virtual world.


Most of your happiness at work is based on personal relationships. Being able to manage those relationships when things get difficult is key to your success at work — and in life. Jerks at Work is a practical and engaging set of tools. Buy it.”
