Work relationships can be hard. The stress of dealing with difficult people dampens our creativity and productivity, degrades our ability to think clearly and make sound decisions, and causes us to disengage. We might lie awake at night worrying, withdraw from work, or react in ways we later regret—rolling our eyes in a meeting, snapping at colleagues, or staying silent when we should speak up. Too often we grin and bear it as if we have no choice. Or throw up our hands because one-size-fits-all solutions haven’t worked. But you can only endure so much thoughtless, irrational, or malicious behaviour—there’s your sanity to consider, and your career. Amy Gallo is an expert in conflict, communication, and workplace dynamics. She combines the latest management research with practical advice to deliver evidence-based ideas on how to improve relationships and excel at work. She is the author of the HBR Guide to Dealing with Conflict, a how-to guidebook about handling conflict professionally and productively, and the forthcoming Getting Along: How to Work with Anyone (Even Difficult People). In this interview, I speak to Amy Gallo about the archetypes of people we encounter in the workplace and how we can understand and deal with challenging workplace relationships more effectively. We discuss the principles that will help us build stronger, more resilient relationships, and look at the tools we can use to rebuild fractured ones.
