The staffing industry has been very good at one thing: filling a seat. It has been far less good at protecting the household, the family office and the long-term vision they are meant to serve. Three numbers from the Valmore UHNWF Staff Retention & Impact on OPEX-CAPEX tri-continental study, read together, describe a structural failure rather than a run of bad luck.

The placement-first business model
Three out of four mandates in this market are monetised at the moment of signature. The fee is earned when the candidate starts, not when the candidate stays. Everything the family actually needs — governance, reporting lines, a real onboarding, a compensation structure that survives year two — sits outside the billable event. The incentive is speed, not stewardship.
That is why a family can pay a full placement fee three times in eighteen months for the same position and never be told why the role keeps failing. Nobody in the transaction is paid to diagnose it.
The HR competence gap
More than nine in ten recruiters working with private households have no formal training in human resources, employment compliance, performance management or organisational design. They are salespeople with a candidate database. They can describe a résumé; they cannot design a role, calibrate a pay band, write a governance structure, run a probation review or de-escalate a conflict inside a residence where the employer and the employee share the same roof.
Private service is one of the few employment environments where the workplace is a home, the manager is the principal, and the smallest interpersonal failure becomes a daily one. It is precisely the environment that demands the most HR sophistication, and it is the one receiving the least.
What it costs the family
The cost is rarely presented as a single number, so it is rarely confronted. It accumulates: repeated fees, salary overlap during handover, interim coverage, lost institutional memory, vendors and contractors re-learning the property, security exposure during the gap, and the principal's own time absorbed by problems the structure should have prevented. Across five years, families in the study reported OPEX and CAPEX leakage above 15% of household operating cost, commonly between US$300,000 and US$800,000 per residence.
The single most expensive line is not the fee. It is the operating memory that walks out of the door with the person who held it.
What a partnership model looks like
A firm accountable for the long term does the work the placement model skips:
It writes the role with a governance structure — who decides, who approves, who is informed, and how the family office, Valmore, the estate or house manager and the principal relate to each other.
It calibrates compensation against the market and against the family's real service level, so year two does not become a resignation.
It runs a structured 90-day onboarding with documented systems, vendors, protocols and property knowledge, so the house is not dependent on one memory.
It keeps an operating memory of the residence — records, protocols, vendor history, maintained continuously and independently of any individual employee.
It stays accountable after the start date, with scheduled reviews, performance support, and replacement terms that cost the firm, not the family.
The question worth asking
Before the next mandate, a principal should ask one question of any agency: what are you accountable for after the candidate starts? If the answer is a guarantee period and nothing else, the answer is placement. Families who are quietly losing their best people are not being failed by the labour market. They are being failed by a service model that ends at exactly the moment their real risk begins.
