Fractional CHRO Services for Companies Between 50 and 500 People
A senior HR executive one to three days a week, placed on our W-2, who sets the architecture your team then runs without her.
A fractional CHRO is a senior HR executive you buy one to three days a week instead of hiring full time. KORE1 places them with companies between 50 and 500 employees, then staffs the contract HR seats they scope.

- A part-time HR executive on a standing weekly cadence, what she decides, and what happens to the work once she has decided it.
- Covered elsewhere
- A full-time temporary leader covering one empty seat is interim management. The HR practice as a whole, every level, is human resources staffing. The other fractional seats sit under fractional executive placement.
Somewhere around 80 employees, the people work stops being something your CFO can hold on a Friday afternoon. Handbooks go stale. Quietly. Two managers hand out the same title at a $30,000 difference. A manager asks what the promotion rule is and nobody has written one down. Awkward pause.
None of that needs a full-time CHRO. All of it needs a CHRO once.
That distinction is the whole reason this page exists. The expensive judgment in an HR function is front-loaded, and most of what follows it is application. We place the executive through contract staffing, on a fixed weekly cadence, and we staff the seats she scopes afterwards from the same desks. Your leadership team still owns the decisions she frames. She is not a managed service. She does not arrive with a methodology either.
What She Actually Does on Two Days a Week
The honest answer is that she spends the first six weeks finding out what you already have, because almost every company at this size has more HR structure than it thinks and less than it needs. Offer letters that contradict the handbook. A bonus plan three managers describe three different ways. Job titles that were a recruiting concession in 2024 and are now a compensation problem nobody can unwind without telling four people their level was never real. Nobody enjoys that meeting.
After that it narrows fast. Very fast. She writes the job architecture, sets the bands, decides who signs a requisition, and takes the handful of calls a week that genuinely need a head of people. Investigations. An offer above band. A counteroffer. A manager who has to be managed out. The org design question that gets asked once a quarter and has to be answered the same way both times. Same answer, twice.
What she does not do is run the function day to day, and a good one will tell you so in the first conversation. If what you need is somebody to administer benefits, keep the HRIS clean and answer employee questions, that is an HR generalist and we will say so. Cheaper for you. Much cheaper. We would rather be right. It has cost us the bigger placement more than once.
One Board, Then Eighty-Seven Impressions
A stencil gets cut once, by somebody who knows what the letters have to say. After that anyone can spray it on a crate, and every crate comes out the same. Three of the things a fractional CHRO cuts work exactly like that. Here is what each one costs to cut, and how many times it gets used in the first year at a 250-person company.
- Job architecture Seven levels, four job families, one written promotion rule. 12 CHRO days, once87 pay and level decisions in year one, every one of them priced off that one board. Plus 2 that do not fill a mark.
- Pay band structure A range and a midpoint per level, defensible as a good-faith range. 10 CHRO days, once65 postings and offers in year one, every one of them priced off that one board.
- Requisition rule Who signs a backfill, who signs a new seat, and what each needs first. 4 CHRO days, once65 requisitions in year one, every one of them priced off that one board.
Reading the figure
- The board. One decision, written down once, in a form somebody else can use without you.
- The cut. The judgment that needs the title. The bar across it is the tie, which is what keeps the cut from falling out of the board.
- The impression. One application of that decision, sprayed by whoever is holding the req. The gap is the tie, which is how you can tell it came off this board.
- One mark is five applications. So the marks on a track, times five, are the count printed beside it.
Cutting all three took 30 CHRO days, including the talent review that feeds them. A two-day-a-week engagement is about 96 days a year, so the cutting is roughly 31 percent of the first year and almost none of the second. The other 66 days in year one are the calls that cannot be delegated and the escalations nobody can write a rule for in advance.
Then the arithmetic turns over. 65 offers and 22 internal moves get priced against bands she set once, by a recruiter and an HR administrator who cost a fraction of her rate and never have to re-litigate the band.
Illustrative company at 250 employees, not a client file. Separations at 18 percent and growth at 8 percent give 45 backfills and 20 new seats; internal promotions and laterals at 8.8 percent give 22 more priced decisions. Day counts are the shape a first-year engagement takes, not a quote. The arithmetic is derived in chro-work/stencil.py and the impression tracks are generated from it, so the marks and the printed counts cannot drift apart.
Fractional, Interim, or a Full-Time Hire
| Fractional CHRO | Interim CHRO | Full-time CHRO | |
|---|---|---|---|
| Time on site | One to three days a week, standing | Four to five days a week | Full time |
| Why you buy it | You need the decisions, not the hours | The seat is empty and the work cannot wait | People strategy is a board-level agenda item |
| Typical length | Nine to eighteen months, often renewed | Three to nine months, ends at the hire | Indefinite |
| Ends when | The architecture holds without her | The permanent CHRO starts | It does not |
| Headcount size | Roughly 50 to 500 | Any size, usually 300-plus | Usually 500-plus |
| Reports to | CEO, dotted line to the board | CEO | CEO |
The distinction people miss is that interim is about a gap and fractional is about a fraction. An interim CHRO holds a seat that exists and is empty. A fractional CHRO holds a seat that has never existed and probably should not exist full time at your headcount. Two different purchases. If the seat is genuinely empty and genuinely full time, you want an interim executive on full-time cover instead, and we place those too.

She Scopes the Seats, We Fill Them
A fractional CHRO who finishes her first quarter well leaves you with three job descriptions you did not have before. That is the part most companies do not budget for, and it is the part that decides whether the architecture survives her. Budget for it.
Usually it is an HRIS analyst to make the system hold the structure she wrote, a benefits administrator to run open enrollment and the filings, and talent acquisition to work the requisitions against the new bands. Sometimes an HR business partner instead of all three, if the managers are the bottleneck rather than the systems.
We staff those as contract, contract-to-hire or direct hire out of the same practice, which is the practical reason to buy the executive and the seats from one firm. She writes the spec. We already know who is available. Nobody spends six weeks translating. That alone is worth something.
Her last deliverable should be a named employee against each board she cut. If nobody owns the band structure after she leaves, it stops being a band structure in about eleven months. Nobody decides that. It just erodes.
The Posting Rule Is Already Load-Bearing
Here is a concrete version of why the band structure is not a nice-to-have. On October 1, 2026, Connecticut Public Act 26-12 replaced the state wage-range statute. An employer may no longer fail to disclose, in an internal or public job advertisement, the wages or wage range for the position and a general description of the benefits offered with it.
Three details matter more than the headline. There is no employee-count floor, so the rule reaches an employer using the services of one or more employees for pay. It covers internal postings, which is where most companies have no range at all. And it follows the reporting line, so a role performed outside Connecticut still counts if the person reports to a supervisor, an office or a worksite in the state.
The statute also now defines a wage range as the range an employer sets in good faith. Good faith is not a number you can produce on the morning a req opens. It is a band structure, documented, with a midpoint and a reason. That is a board somebody has to cut before the first posting goes out, and it is the kind of thing a company discovers three days late. Avoidable, and expensive.
Read from the text of Public Act 26-12, Sec. 2, which repeals and replaces Conn. Gen. Stat. 31-40z effective October 1, 2026. Nothing here is legal advice, and counsel in each state you post into should review your ranges.
How a KORE1 Fractional CHRO Engagement Works
- Name the decisions, not the hoursWe start from what has to be decided in the next two quarters. Comp philosophy, leveling, a reduction, an acquisition, a posting obligation in a new state. The day count falls out of that list. Buying days first is how companies end up paying executive rates for administration, which is the single most common way a fractional engagement goes wrong in the first quarter and the hardest one to unwind once a cadence has been agreed and announced internally.
- Set the cadence before the searchOne, two or three fixed days a week, same days each week, because a floating schedule means your managers never learn when she is reachable. Three days is usually a first-year shape that steps down to one, because the volume of genuinely executive decisions is front-loaded into the months when the architecture does not exist yet and almost nobody needs that same volume in year two.
- Shortlist from the executive desksFour to six candidates who have held the seat at your headcount, not one size up. Somebody who ran people for 4,000 employees is often the wrong hire for 180, and it is a mistake that looks good on paper, because the resume reads as a step up for you when the actual skill you are buying is the judgment to build a function from very little rather than the judgment to run a large one that already works.
- Agree what gets written downThe engagement letter names the artifacts, not just the days. Job architecture, band structure, requisition rule, whatever else your list produced. Artifacts are how you tell whether a fractional engagement is working in month four.
- Staff the seats she scopesAs each board gets cut, we fill the contract seat that will apply it. This usually starts in month two and it is the step companies skip.
- Hand back, then step downA named employee owns each artifact, the cadence drops to one day a week or to monthly, and the engagement ends on a deliverable rather than a date. If there is a full-time CHRO to hire eventually, she is usually the best person to help you write that job.
When This Is the Right Purchase
-
Good fit
Growing through 100
Headcount doubled, nobody owns leveling, and two managers are quietly paying different rates for the same job.
-
Good fit
First institutional round
A new board wants an equity plan, a comp philosophy and a people slide that holds up to diligence.
-
Poor fit
The seat is empty
Your head of people left last month and the work is full time already. That is interim, not fractional.
-
Poor fit
You need hands
Benefits, onboarding and employee questions are the backlog. Buy a generalist and keep the executive budget.
Common Questions
What does a fractional CHRO do that an HR director cannot?
She sets the structure an HR director then runs. Job architecture, pay bands, the promotion rule, the requisition rule, the people case that goes to a board. A strong HR director can operate all of that well and will usually tell you honestly that writing it from nothing is a different job. The gap is authority as much as skill, because half of this work is telling a founder that a title he promised cannot survive a band structure. That is a hard conversation. It needs rank.
How much does a fractional CHRO cost?
Price it as days, not as a salary fraction. The BLS puts the median wage for human resources managers at $149,280 as of May 2025, and a CHRO at a 250-person company sits well above that, so a fixed weekly day rate is the only honest way to compare, and anybody quoting you a flat percentage of a notional full-time salary is pricing a product rather than pricing the decisions you actually need made this year. What moves the number is the day count, the seniority you actually need at your headcount, and whether the engagement includes building the artifacts or only advising on them. Two days a week for nine months is a very different purchase from one day a month.
Is fractional the same as interim?
No. Interim is full time for a short period, usually to cover a seat that exists and is empty. Fractional is part time on a standing cadence, usually for a seat that has never existed. One is about a gap. The other is about a fraction. Companies conflate them and then buy five days a week of judgment they only needed two days of.
At what headcount should we stop using a fractional CHRO?
Most companies outgrow it somewhere between 400 and 600 employees. The signal is not headcount. It is escalation volume. When the calls that genuinely need a head of people stop fitting into the days you bought, you are buying a full-time seat in instalments. That is the conversation to have at renewal. Not after it.
Will a part-time executive actually have authority here?
Only if she reports to the CEO and shows up on the same days every week. Both of those are structural, and both get negotiated before the search starts rather than after somebody is in seat, because a reporting line is nearly impossible to change once an organisation has watched where a new executive sits for a month. The failure mode is predictable. A fractional CHRO routed through a COO, on a floating schedule, becomes an expensive consultant inside about two months. Every time.
Do we still need HR staff if we have a fractional CHRO?
Yes, and more of them than people expect. SHRM put the median at 1.98 HR staff per 100 employees in 2025, up from 1.58 in 2017, which is roughly five people at a 250-employee company. A fractional CHRO does not replace that team. She decides what it should be doing, then we staff the HRIS, benefits and talent-acquisition seats she scopes.
Can she help us hire our first full-time CHRO?
That is one of the better uses of the engagement. She has already found out what the job is at your company, which is the part most first CHRO searches get wrong. She writes the spec. She sits on the loop. She hands over the artifacts she cut. Our executive search desk runs the search itself so there is no conflict in her recommending a candidate.
