Counter-offers feel like saving a hire. The data says they mostly delay the inevitable. Here's the framework that actually works.
Across industries, roughly 50–60% of accepted counter-offers result in the employee leaving anyway within 12 months. In commercial mechanical specifically, the number trends higher — closer to 65%. The reasons that drove the candidate to interview elsewhere rarely get fixed by a raise, and the trust in the relationship is permanently damaged once the employer knows the employee was looking.
Rarely. The honest framework: counter-offer only when (1) the employee is genuinely irreplaceable for a defined period (12–24 months), (2) the underlying reason they were looking is solvable beyond comp, and (3) you have a structural retention plan beyond the raise. If any of the three is missing, the counter-offer is buying delay, not loyalty.
Honest conversation: "We respect your decision. We'd like a clean transition. Let's plan the next 30 days together." Then ask the exit-interview questions — what would have kept them, what we got wrong, who else in the org might be at risk. This conversation is worth more than the counter-offer, because it shapes how you prevent the next departure.
Then the counter-offer is a stopgap, and treat it as such. Pay the bump, set explicit expectations about the next 6 months, and use the bought time to actively recruit the replacement. Tell the employee plainly: "We're matching this so we can plan a thoughtful transition. Long-term, we both need to figure out whether this is the right seat for you." Don't pretend the counter solved the underlying issue.
Direct cost: the raise (typically 12–25% of base). Indirect costs: damaged trust with peers who learn about the counter and now feel under-leveraged, comp compression with the rest of the team (their salaries are now anchored to the counter level), and the eventual second exit when the underlying issue resurfaces. The all-in cost is typically 2–3x the raise number.
That's a structural signal, not a counter-offer problem. When two or more key people are interviewing simultaneously, the root cause is leadership, comp positioning, project mix, or culture — not market conditions. Counter-offering one or two of them treats the symptom and accelerates departures of the rest, who watched the conversation and now know how to negotiate.
Three practices: (1) bench-mark comp against market every 18 months, not at every annual review (annual cycles lag the market by 12–18 months in tight roles), (2) run skip-level conversations with key people twice a year so issues surface before they trigger a job search, (3) build a real internal advancement path so people don't have to leave to get promoted. Counter-offers are almost always a symptom of one of these three being broken.
