News : In the 9th edition of their barometer on day-to-day HR, published on 10 April 2026 among more than 600 French HR professionals, Editions Tissot and PayFit find that 60 % of HR professionals still spend at least half their day, four hours or more, on administrative tasks, and that 54 % name lack of time and resources as the leading obstacle. 69 % consider the job is becoming markedly more complex and 78 % report being approached more often by employees in 2026 (Editions Tissot and PayFit, 10 April 2026).
Outsourced HR means entrusting all or part of the human resources function to an HR professional from outside the company, who exercises it on your behalf. On a fractional basis, that person works a fixed number of days each week, over the long run, embedded in your organisation: it is neither a one-off consulting assignment nor a piece of software.
That barometer describes companies that already have HR. In a small or mid-sized company that has none, the volume does not disappear: it spreads across people whose job it is not, the owner-manager in the evening, the executive assistant between two files, the accountancy firm asked questions about which collective agreement applies. It holds for a while. Then a badly drafted contract or a poorly prepared departure is a reminder that the HR function did exist all along: it is simply that nobody was holding it.
I am Christine Martin, an independent HR consultant. I work as a fractional outsourced HR professional with directors who have passed that point. Here, plainly, is when this solution is the right one, and when it is not.
Outsourced HR: what exactly is being described
What changes everything is recurrence: I come back every week, so I see subjects arriving before they blow up. After a few weeks I know your employees, your managers and the collective agreement that applies to you. I do not hand over a report: I take the files and I run them. This is neither a supplier called in an emergency nor an HR software package.
It should not be confused with outsourcing one isolated brick, payroll handed to a firm, recruitment handed to a headhunter. Those are useful pieces of subcontracting, but they do not create an HR function. To know what can be delegated and in what order, see which HR tasks to outsource first.
Six situations where outsourcing HR becomes the right decision
It is never theoretical considerations that trigger the decision. When a director calls me, there is almost always a specific event behind it: an employee who has just resigned, a formal notice they do not know how to answer, a manager at the end of their rope. Here are the six situations I come across most often.
- The HR load has become weekly. As long as an HR question lands once a month, the director absorbs it. When several land each week, a sick leave, a request for a negotiated termination, a disagreement between two managers, that absorption happens at the expense of selling.
- You are recruiting at a sustained pace. Contracts, probation periods, onboarding: what was improvised for two hires a year does not hold at eight.
- A sensitive employment issue is on the table. A conflict, a declaration of unfitness for the job, a reorganisation, setting up the staff committee. These are subjects where improvising is expensive, and expensive for a long time.
- You no longer keep up with employment law. It moves continuously. Law no. 2026-403 of 26 May 2026 on simplifying economic life (in French), published in the official journal of 27 May 2026, carries 84 articles across twelve headings and has, since 28 May 2026, removed the obligation to file the internal rules with the registry of the labour tribunal. Without a watch on this, a company applies obligations that have lapsed, or misses the relief it is now entitled to.
- Your HR manager is alone and saturated. It is not always an absence of HR: sometimes it is an isolated HR professional with nobody to weigh decisions against.
- You are a subsidiary and headquarters sits abroad. A particular case, treated separately in the article on building the HR function of a French subsidiary.
What a fractional HR professional actually takes on
The scope is not standard, it is built with you, and that is the principle of my HR support. Here is what it covers most often.
| Area | What I take on | What stays with you or with a specialist |
|---|---|---|
| Personnel administration | Contracts, amendments, absences, personnel files, the relationship with the payroll firm | The technical production of the payslip |
| Recruitment and onboarding | Defining the need, interview frameworks and interviews themselves, the onboarding path | The final hiring decision |
| Day-to-day employment law | The applicable collective agreement, framing procedures, preparing files | Litigation and legal characterisation: an employment lawyer |
| Management and development | Annual and career appraisals, the skills plan, support to managers | Day-to-day team leadership |
| Employee relations and organisation | Preparing meetings, setting up the staff committee, supporting reorganisations | Negotiating complex collective agreements |
One point I prefer to make early: I am an HR professional, not a lawyer. I make your practices safer and I alert you when a subject leaves my scope. On litigation or a contentious clause, I point you to an employment lawyer.
Why fractional rather than an in-house HR hire
The question is not “outsource or recruit”, it is “at what volume does an in-house post become justified”. As long as the need does not fill a week, a full-time post creates another problem: either you over-size it, or you recruit a junior profile for a need that calls for experience.
Fractional work settles that differently: you buy a level of competence, not a number of hours. An experienced HR professional two days a week rather than a beginner five days, with the flexibility to adjust the rhythm.
There is a downside, and I prefer to state it: I am not there the other three days. That calls for fixed check-ins, clear decision paths and managers who know what to handle without me. The full comparison with an HR consultancy and an in-house hire is set out here.
How an outsourced HR assignment actually runs
I work on assignments of two days a week minimum, over the long term. That is not a commercial preference, it is a condition for the work to be effective: below that, the time goes on emergency administration and nothing gets structured.
- An initial conversation. You describe your situation, and I tell you frankly whether your need calls for a fractional HR professional or for something else.
- A stocktake. This is where the surprises come out: a collective agreement applied for years without matching the actual activity, amendments never signed, overtime mishandled for a long time.
- A prioritised plan. First what exposes the company, then what structures it, finally what develops it.
- The steady rhythm. Fixed days in the week, on site, with a regular review with the leadership.
On physical presence I am categorical: part of HR work cannot be done remotely. You do not sense a team’s climate through a screen. The Morgan Philips barometer of interim management in France (in French), published on 4 May 2026, confirms it: 47 % of assignments run fully on site and 89 % include at most two days of remote work per week.
When outsourcing your HR is not the right answer
Outsourcing does not suit every situation. Here are the cases where I say so plainly.
- You need a legal answer, not an HR function. Ongoing litigation, a procedure already under way: go and see an employment lawyer, straight away.
- Your need is purely technical. If all you are looking for is payslips, a payroll firm will be enough.
- You are looking for cover with no intention of changing anything. An outsourced HR professional with no access to leadership and no mandate to decide is of no use. I have seen assignments stop for that reason alone.
- Your HR volume fills a full week, lastingly. At that stage, recruit, and I am happy to help recruit the person.
- You expect the whole thing to be steered remotely. Without presence on site, the support loses most of its value.
This article does not deal with the level of seniority you need either: an HR director, a generalist or administrative support do not answer the same questions, and that is the subject of the article on the fractional HR director. On choosing the person, see the criteria for an independent HR consultant.
FAQ
What is outsourced HR for a small or mid-sized company?
It is entrusting the human resources function to an outside professional, who exercises it for the company instead of being employed by it. On a fractional basis, that person works fixed days each week and covers personnel administration, recruitment, employment law and support to managers.
At what company size should HR be outsourced?
There is no official headcount threshold. The right indicator is frequency: when HR subjects arrive every week and nobody in the company has the skill or the time to handle them, the function exists in fact, and all that is left to decide is who holds it.
What is the difference between outsourced HR and fractional HR?
Outsourced HR is the principle: the function is carried by someone from outside. Fractional is the format: that person works for several companies, a fixed number of days a week in each, with a recurring, long-term presence.
Can an outsourced HR professional handle payroll?
They steer payroll and take on everything upstream, variable elements, absences, checking the payslip, the relationship with the firm, without necessarily producing the payslips. With most of my clients, production stays with the payroll firm or the chartered accountant, and I make the link.
Does an outsourced HR professional replace an employment lawyer?
No. I frame practices, prepare files and check that the collective agreement is applied. As soon as there is legal characterisation, litigation or a risk before the labour tribunal, the employment lawyer takes over, and I tell you when that point is reached.
