The single most important thing you can do for your career is to build your network. Whether you build relationships with champions and advocates, coaches and mentors, or people that act as a resource, each one of them provide a benefit that can help move your career forward. Champions and advocates will support you and your ideas—they'll speak up for you in rooms you're not in, recommend you for stretch assignments, and give visibility to your contributions. Coaches and mentors will help you grow by offering guidance, feedback, and perspective from someone who's been there before. They help you avoid pitfalls, refine your approach, and accelerate your development. Finally, people who act as resources—whether subject matter experts, connectors, or peers in other departments—help you get things done faster, smarter, and more effectively. Each category adds a layer of strength to your career foundation, and together, they create a powerful support system that can help you rise.
But, sometimes -- whether intentionally or not -- you can jeopardize your relationship with someone and potentially even destroy it permanently. It might be because you disappeared after getting what you needed, failed to follow through on a promise, or didn't acknowledge the role someone played in your success. Other times, it could be as subtle as not showing appreciation, taking credit for shared work, or consistently making interactions one-sided. These moments can leave the other person feeling used, undervalued, or disrespected. And when trust is broken, it's incredibly difficult to rebuild. Relationships, especially in your career, are built on mutual respect, reliability, and reciprocity—once that's compromised, even unintentionally, the consequences can follow you far beyond that one interaction.
Or maybe YOU'RE the one on the other side. Maybe you've spent time fostering a connection with someone only for them to turn their back on you. They've taken advantage of you generosity in order to get ahead and then fail to reciprocate. That kind of experience can leave you feeling betrayed, used, and questioning whether it's even worth investing in people again. It stings when someone you believed in shows that their interest in you was transactional. And while it's tempting to close yourself off after that, it's important not to let one bad experience poison your ability to build meaningful, mutual relationships in the future. Instead, take the lesson with you: be more discerning, set clearer boundaries, and recognize the early signs of imbalance before you're left holding all the weight.
Why do people burn bridges?People don't always burn a bridge because of spite. In fact, they often don't even realize that they are doing it; it just sort of happens. Let's take a look at some of the common reasons that people burn bridges and how to handle each of them.
They've gotten what they need from the relationship. If someone has achieved their goal, they may feel like they no longer need the relationship. Or maybe they never intended to maintain the relationship at all, just get their needs met and move on. Any time you reach out to them, you just get ghosted. You may even see them put someone else in your position as they look to climb the next rung.
