What counts as a bad hire
A bad hire is not necessarily a bad person. Most mis-hires are capable people in the wrong role: the scope was different from what was described, the salary attracted the wrong level, the manager and the person did not work, or the business needed something it had not articulated. The result is the same either way: someone leaves, or is asked to leave, within the first year, and the business starts again.
We see three patterns most often in senior and specialist roles:
- The wrong level. A role budgeted at $110,000 that really needed a $140,000 person. The person hired is competent but out of their depth, and the gap shows within months.
- The wrong shape. The job description combined three functions; the person hired is strong in one and struggles in the others.
- The wrong fit with the manager. A structured, process-driven leader hired by an informal, fast-moving owner. Both are good; together they are miserable.
Each of these was decided before the first interview, in how the role was defined. That is the point of this guide.
Worked example: a mis-hired Operations Manager
Take a 60-person Waikato manufacturer that hires an Operations Manager at $130,000. The role was advertised in-house after a quick conversation about what was needed; the salary was set at what the previous person earned five years ago; the successful candidate had run a smaller, simpler site. It becomes clear by month four that the role is beyond them. They are managed out at month nine. The role is vacant for a further twelve weeks while a proper search runs, and the replacement takes four months to reach full effectiveness.
| Item | Basis | Cost |
|---|---|---|
| Salary paid for below-par performance | 9 months at $130,000, with output around half of what the role should deliver; count the wasted half | $48,750 |
| Original recruitment | Advertising plus around 50 hours of owner and manager time | $7,000 |
| Onboarding and ramp-up of the first hire | Training, manager time, reduced effectiveness in the first months | $12,000 |
| Operational damage during the nine months | Delivery performance slips, an improvement project stalls, overtime and rework rise. Conservatively 1.5% of a $7m operating budget over nine months | $78,750 |
| Managing them out | Performance process, legal advice, any settlement, owner time | $15,000 |
| Vacancy while the replacement search runs | Owner covers operations for 12 weeks; their own work stops | $25,000 |
| Replacement search | Illustrative agency fee at 15% of a corrected $150,000 salary, plus internal time | $26,500 |
| Replacement ramp-up | New person at an average of 60% for 4 months | $20,000 |
| Team impact | One supervisor leaves during the turmoil; a second is disengaged for months | $15,000 |
| Total | $248,000 |
Nearly twice the salary of the role, on conservative assumptions, and the customer who left when deliveries slipped is not counted. Neither is the owner's stress, or the eighteen months the business spent standing still. The saving that started all this, skipping a proper brief and a benchmark to get the advert out quickly, was worth perhaps a week and a few thousand dollars.
The general finding from research on mis-hires is consistent with this: for management and specialist roles, a bad hire costs somewhere between one and three times the annual salary. Our employee turnover cost guide gives a method you can apply to any role.
Warning signs, and when they appear
Mis-hires are usually visible early to anyone who is looking. The signs by stage:
During recruitment
- The shortlist is thin or all at the wrong level, which usually means the salary or scope is off
- The preferred candidate's experience is a size or a complexity below the role, and everyone is rationalising it
- References are lukewarm or the candidate is reluctant to provide people who reported to them
- The hiring decision is driven by urgency: "we need someone in by the end of the month"
In the first 90 days
- They are not asking questions, or are asking the same ones repeatedly
- The team is going around them to the owner
- Routine deliverables, such as the weekly numbers or the production plan, are late or need correcting
- They avoid the floor, the site, or the difficult conversations
- Their manager has stopped mentioning them, which usually means concern that has not yet been voiced
Months four to nine
- Key metrics are drifting and the explanations are external
- Good people in the team start leaving or asking about other roles
- The owner is back doing the job they hired someone to do
The earlier the sign, the cheaper the response. A structured onboarding process with honest 30, 60 and 90-day check-ins exists partly to surface these early. So does our post-placement follow-up, where we speak separately with the candidate and the client in the first months, because people will say things to us they are not yet saying to each other.
Why the fix is at the brief
Almost every mis-hire we have been asked to help recover from traces back to the same place: the role was not properly defined before the search began. The business knew what outcome it wanted, but the position it advertised did not match what the business actually needed, in scope, level or salary. We wrote about this in detail in why taking a brief is the shortcut to a mis-hire.
A proper brief does four things a quick one does not:
- Defines outcomes, not tasks. What must be different in six and twelve months. This sets the level.
- Tests the scope. Is this one job? Can one person realistically do it? If not, restructure before advertising.
- Benchmarks the salary against the current market, not against what the last person earned. Under-market pay attracts under-level candidates. See salary benchmarking.
- Describes the manager and the culture honestly, so that fit can be assessed rather than hoped for.
In the worked example above, a proper brief would have identified that the role had grown since the last incumbent, that the salary was $20,000 under market for the scope, and that the owner needed someone who had already run a site of this size. The search would have taken a week longer and cost a fee. It would have saved a quarter of a million dollars.
Reducing the risk at each stage
- Brief: write the job description around outcomes; benchmark; test whether the role is realistic.
- Search: reach passive candidates, not just applicants. The strongest people for senior roles are usually employed and not looking.
- Interview: structured questions against defined capabilities, the same for every candidate. See our interview questions for managers.
- Reference: speak to people who reported to the candidate as well as those they reported to. Ask about the specific capabilities the role needs.
- Offer: be honest about the business, the challenges and the manager. Surprises after the start date are how placements fail.
- Onboard: a written 90-day plan, a weekly one-on-one, and an outside voice checking how it is really going.
- Act early: if the signs are there at day 60, address them at day 60. Waiting until month six does not make the conversation easier; it makes it more expensive.
If you have a bad hire now
First, be honest about whether it is the person or the role. If the role is unrealistic, changing the person will not fix it, and the same thing will happen again. If it is the person, act with a fair process and get advice; New Zealand employment law requires it, and a rushed exit adds legal cost to everything else. If you relied on a 90-day trial period, check it was valid before you lean on it.
Then run the replacement search properly. Start with the brief, benchmark the salary, and consider interim cover so the search is not conducted under pressure. That is exactly the work we do, and we are happy to have a candid conversation about what went wrong and how to avoid repeating it. Get in touch, or read about how we approach permanent recruitment.
