Counter-offer from current company after I resigned, should I stay?

From my experience, counter-offers are usually a short-term fix that ends badly, and I regret accepting one. The company matched my pay, but the reasons I wanted to leave, poor growth and a difficult boss, didn't change, and within a year I was unhappy again and left anyway, having burned some trust by staying. Ask yourself why you were leaving in the first place. If it was purely money and everything else is great, a counter-offer might be fine. But if it was culture, growth, or management, the extra pay won't fix that. Also, once you've signalled you'll leave, some managers quietly view you as a flight risk and may pass you over later. Money they suddenly find now makes you wonder why they underpaid you before. Think about the whole picture, not just the matched number.

I turned down a counter-offer and I'm glad I did. The classic pattern is: they match your salary now because replacing you is expensive and inconvenient, but the underlying issues remain and your loyalty is now in question. Studies and plenty of anecdotes suggest many people who accept counter-offers leave within a year or two anyway. My advice: revisit the exact reasons you started job hunting. If the new role genuinely offers better growth, environment or learning, don't let a quick pay bump keep you stuck. Also consider how it looks to the new employer if you back out after accepting, that bridge can burn. Be professional and honest with your current boss when declining. Sometimes staying makes sense if they also fix the real issues in writing, but salary alone rarely does. Trust the reasons that made you look elsewhere.
