What does 'burning your bridges' mean?

What it means: To permanently damage a relationship or opportunity so there's no way to go back. The image is military: if you burn the bridge behind you, there's no retreating. In social and professional life, burning bridges means ending things in a way that makes reconciliation or returning impossible.

• "Don't burn bridges when you leave a job - you never know who you'll need."
• "She burned every bridge she had at that company."
• "I disagreed with the decision, but I didn't want to burn the bridge."

Why it matters professionally: Former colleagues become references, clients, partners, or future employers. Leaving badly - being hostile, bad-mouthing the company, causing conflict on your way out - burns bridges that may matter later.

• "Leave on bad terms" - plain description
• "Cut ties" - less aggressive, sometimes mutual
• "Part on bad terms" - describes a rupture without assigning blame
• "Don't go out with a bang" - informal advice to leave quietly

Register: Casual to professional. A well-known phrase that works in most contexts.
