When Fractional HR is the right answer
Not every HR gap needs a full-time position. Between 50 and 150 employees, most companies have a small HR team that handles contracts, payroll and recruiting properly, but nobody with experience in organisational questions, employment law and working with a works council (Betriebsrat, the elected employee representation in German companies). A full-time head of HR would be too much for that volume. None at all is too little. Three situations in which Fractional typically fits:
Too small for a full-time head of HR
50 to 150 employees, an HR team without an experienced lead, but not yet the volume for a full-time position.
Stepping down from an interim engagement
An interim engagement is ending, a permanent hire is not yet the right investment. Fractional keeps the level.
Experience, not just administration
There is administrative HR capacity, but nobody with experience in organisation, employment law and works council matters.
The scope models
The scope follows company size and situation, not a rigid package. Two models cover almost every case, and a third is the transition:
One fixed day a week
For companies up to about 100 employees with predictable daily business. Decisions, sparring, priorities for the week.
Two fixed days a week
For higher volume or an ongoing restructuring that needs more presence: works council, line managers, systems.
Switch to interim when needed
If the need grows, through expansion or a restructuring, we move together into a full-time engagement, without a restart.
Which role, fractional
All three roles also run on fixed days, with the same scope as full-time, just condensed:
Interim HR Manager, fractional
HR leadership on fixed days: leading the team, works council, decisions. Fits when the team runs and leadership is missing. See the role
HR Business Partner, fractional
One fixed day of sparring for the managing director and line managers. The most common fractional model. See the role
HR Operations, fractional
Processes and systems built on fixed days, the team implements in between. See the role
What a fixed day looks like
A fractional day is not an office day with an open door. It is a structured day with fixed blocks. Otherwise it frays into follow-up questions, and by evening nothing has been decided.
Everything that has piled up since the last day and needs a decision: contracts, cases, approvals.
Fixed appointments with the managers who currently have a case. Prepared, talked through, decided.
The project of the quarter: compensation system, HRIS, works agreement, onboarding. One topic, not five.
What the HR team implements before the next day, what waits, what comes to me. One page to the managing director.
Fractional or Interim?
Fractional fits an ongoing need without full-time volume. Interim fits a vacancy or a time-limited restructuring that needs full attention.

Contract and legal certainty
Fractional HR runs as a services contract on a day-rate basis, not as an employment relationship. For it to stay that way under German law, the contract and the lived practice have to match: several clients, freedom in how the work is done, own equipment, no integration into the organisation the way an employee would be. The risk to avoid is what German law calls Scheinselbständigkeit, false self-employment, where a contractor is treated like an employee and social security contributions become due retroactively. I work for several companies in parallel as a matter of principle, with my own laptop and licences, and report to the managing director as a contractor.
The twelve check points you can use to test this yourself are under Fractional HR and employment status. Anyone who wants certainty applies for a status determination with the German Pension Insurance (Deutsche Rentenversicherung); I supply the documents for it.
How the cost is made up
A day rate, as with interim, just on fewer days a week. The day rate is in a similar range because the same experience is brought in, and the total cost per month is correspondingly lower. The useful comparison is a part-time head of HR as a permanent hire, whose search takes about as long as for a full-time position. The logic with a worked example: What Fractional HR costs.

Frequently asked questions about Fractional HR
How quickly can a fractional engagement start?
Usually with four weeks' lead time, so that handover and scheduling run cleanly. If the need is acute it can be faster, and I say so on the first call.
What is the minimum term?
Three months, then open-ended, with four weeks' notice on both sides.
Am I tied to a specific weekday?
The day is agreed jointly and normally stays fixed for the term, so that the team and the works council can plan around it. Changes by agreement are possible.
Does this apply to all three roles?
Yes. Interim HR Manager, HR Business Partner and HR Operations all run on fixed days too, depending on which gap you are closing.
What happens on the days in between?
Your team works to the priorities set on the fixed day. For urgent matters I am reachable, everything else waits for the next day. That forces prioritisation, and that is the point.
Is Fractional HR legally sound in Germany?
Yes, if the contract and the practice match: several clients, freedom in how the work is done, own equipment, day-rate basis. The twelve check points are under Fractional HR and employment status.
