Good people leave long before they hand in their notice
The most consistent reason good employees leave is due to the relationship with their immediate manager. Not the company, not the salary, not the commute; the manager. A well-functioning team; one that’s collaborative, relatively flat, and engaged, can fragment quickly when a new manager arrives and starts making structural changes without any explanation. Actions such as separating the team into a senior group and everyone else or duplicating meetings where a single meeting was sufficient can alienate long-standing staff. For long-tenured and senior staff, this can be a catalyst to seeking new opportunities.
The other driver for high turnover, particularly for high performers, is the absence of career progression. Employees who lead through the quality and merits of their work rather than through internal office politics or visibility, tend to stay as long as they can see a path forward. For those early on in their careers- younger or workers entering the workforce, the window is short. If the career progression is not visible relatively quickly, they are more likely to move on quickly. For more experienced employees with greater financial commitments and stability, the patience may extend to eight or ten years. Eventually, though, the same calculation applies.
The pay rise won’t fix it
Retention is almost always framed as a compensation problem, where employers assume that any employees have enough, they will stay. The evidence, and the experience of working alongside businesses through difficult periods, suggests otherwise. A salary increase might buy three or six months. However, it rarely addresses the reason an employee started looking for new opportunities in the first place. In some cases, it could accelerate the employee's departure, because it gives the employee a number, a stronger benchmark to leverage when negotiating a new salary, with their next employer.
The signs you are probably missing
Employers consistently say they did not see it coming. In most cases, they did not look. The signs are physical, visible, and appear well in advance of a resignation letter.
The most reliable early indicator is an increase in sick leave. A previously engaged employee who is disengaging will often start using sick leave as breathing room. It’s a way of creating distance from a workplace that has become difficult, and by the time the pattern is obvious, the relationship is already significantly damaged.
Other warning signs include: the colleague who used to offer a good morning and now walks past without eye contact. The employee who delivers exactly what is asked for but with a flatness they did not previously have. Someone who stops contributing ideas in team meetings after years of being the first to speak. These are symptoms of a deteriorating relationship, not a performance issue. Treating these issues as performance issues, which some managers do, can accelerate the departure considerably.
By the time someone is asking for a pay rise, the problem is typically well advanced. Money is rarely the true root cause.
Quiet quitting is the last stage, not the first
Quiet quitting is defined as disengaging progressively and shifting to doing only the required minimum, and is typically where the story usually ends, not where it begins. It often tends to be the response of someone who has been trying to be heard for a long time only to conclude that no one is listening.
It is most common among people who have invested significantly in an organisation. Employees who have invested years of loyalty, built relationships, carried institutional knowledge, and eventually decided there is nothing left to offer. Sham restructures, where a long-serving employee’s role is disestablished, not because the function is no longer needed but because a new manager wants to reshape the team, are a catalyst for this outcome. People in this situation rarely fight back; instead, they accept it quietly and leave, taking their invaluable institutional knowledge along with them.
On exit interviews: only do them if you mean it.
Exit interviews can provide useful insight, yet they can also be a significant waste of time and resources, depending entirely on whether the employer is prepared to act on what they hear and on the findings from the exit interview.
If the feedback goes into a folder and nothing changes, this communicates to the employees who remain that their views do not matter. The same is true of organisational surveys that produce consistent themes year after year without generating a visible response. Both accelerate the very departures they were designed to prevent.
The question to ask before commissioning is a straightforward one: if the process uncovers some uncomfortable truths, are we prepared to do something about it? If the answer is no, save the money and allocate the resources elsewhere.
What works for retention
Effective long-term retention strategies tend to be less about grand gestures and more about consistent, visible attention to improve employee experience.
Non-monetary benefits can make a significant difference, particularly during periods of high living costs. Subsidised gym memberships, modest medical cover that includes GP visits, a small additional KiwiSaver contribution above the minimum, or access to a nationwide discount platform are all meaningful, high impact, low-cost investments. For example, a healthcare organisation with 170 staff significantly boosted morale by subsidising healthy meals, installed healthy food vending machines in their staff areas, stocked with wraps, salads, and sugar-free drinks. The monthly cost to the employer was between $400 and $500. This success demonstrates that gestures reflecting an organisation's genuine attention to employee well-being resonate far more than complex corporate programs.
What matters to employees, as much as the benefit itself, is how it is communicated. As an example, a total remuneration letter, one that sets out not just base salary but annual leave accrual, sick leave entitlements, KiwiSaver contributions, and any other employer-funded provision, clarifies the full value of the employment package. Without this comprehensive overview, employees often undervalue their current position when comparing competing offers. Transparency ensures the full investment in the individual is recognised.
The real cost of losing someone good
In pure overhead terms, replacing an employee costs around $3,500 in the first 90 days, and that’s before salary is factored in. While this figure accounts for recruitment, induction, and early training, it fails to capture the true cost of lost institutional knowledge.
A handover document is not a replacement for genuine knowledge transfer. A long-tenured employee who has spent years inside an organisation understands its organisational rhythms, historical context, the basis for decision making, the subtle relationships that drive results quietly in the background. This intellectual capital cannot be extracted and passed on. The loss is real, and it compounds across every employee who follows.
If you detect early signs that your employee is disengaging, it is worth having a conversation sooner rather than later with them, and if you are not sure how to approach it with the employee, have that conversation with us. Our initial advice is always free. Retaining a valuable employee is invariably more cost-effective and less disruptive than replacing one.
