Your HR person resigned: how to recover the knowledge that left with her

An HR executive resigns on the 3rd. She has been with the business four years, she is the only person who has ever run payroll inputs, and she is, by everyone's account, excellent. The founder's first reaction is to worry about replacing her. That is the second problem.

The first is that in thirty days a large amount of undocumented reasoning walks out of the building. Not the files — the files stay. What goes is why the night-shift allowance was set at the level it was, which of the three leave policy documents on the shared drive is the one people actually follow, and the fact that two employees have a notice period different from everyone else's.

Extraction, not handover

A handover note is written on the last afternoon and lists where things are. Extraction is different: it happens across the notice period, and it captures decisions, exceptions and timings. Most of what you need cannot be recalled on demand — it surfaces when the work is being done.

So the method is to shadow rather than interview. Sit with her while the month closes, while a joiner is processed, while a confirmation letter goes out, and write down what she does that is not written anywhere. Doing this once for each routine event is worth more than a week of questions.

The order of recovery

Take it in order of what hurts soonest. A month is short and you will not get everything.

1. 1

   Week one — the current month

   Close one payroll cycle with her while you watch. Capture the input list, who sends what, the cut-off she actually uses rather than the one on paper, and every manual adjustment she makes. Manual adjustments are where undocumented rules hide.

2. 2

   Week two — the calendar ahead

   What falls due in the next two quarters, and where the records for it sit. Confirmations, increment cycles, insurance renewals, statutory filings and returns. Have her write the calendar with owners and dates, not a list of topics.

3. 3

   Week three — exceptions and commitments

   Every employee whose terms differ from the standard, and why. Different notice period, retained allowance, agreed flexibility, a promise made at hiring. This is the single highest-value hour of the whole notice period.

4. 4

   Week four — documents and access

   Which version of each policy is current and where it lives, which letter formats are approved, and every system, portal and account she holds credentials for. Transfer ownership rather than sharing passwords.

The questions that surface undocumented rules

General questions get general answers. These get specific ones, and specificity is what you are short of.

• "What did you have to correct by hand last month, and why?" Every manual correction is a rule that exists but is not written.
• "Which employee's terms would surprise me?" Asked directly, this usually produces two or three names immediately.
• "What have you been meaning to fix but never had time for?" Gives you her own list of the weak points, which is more honest than any audit finding.
• "Who outside the company do you deal with, and about what?" Consultants, the payroll bureau, the insurance broker, the PF consultant. Relationships are handover items too.
• "What question do managers ask you most often?" That is the policy most worth writing down before she leaves.
• "If you were away for a month unexpectedly, what would break first?" She has thought about this. Nobody has ever asked her.

Write it down as you go

Record extraction in a form somebody can use, not as meeting notes. One page per process, in the same shape each time, so the successor can read them in any order.

PROCESS:        e.g. monthly payroll input
RUNS:           when it happens and the real cut-off
INPUTS:         what arrives, from whom, in what form
DECISIONS:      what judgement is applied, and by whom
EXCEPTIONS:     named cases that differ, and why
RECORD:         where the output is filed, under what name
OUTSIDE PARTIES: consultant / bureau / broker and what they do
BREAKS IF:      the one thing that would derail this

Eight or nine of these pages cover most of what an HR executive does in a small business. Written during the notice period, they become the first real draft of your HR documentation — which is usually the thing the company had been meaning to do for two years anyway.

What to do in the weeks after

Two things, both easy to skip. First, run the next month without her but with the pages open, and mark every point where the page was wrong or silent. That is your real gap list, and it is short. Second, decide deliberately whether you are replacing like for like.

Many businesses discover at this point that the role had quietly become two: an administrator who keeps records accurate, and a judgement role for the difficult cases. If that is what you find, hiring one person to do both usually recreates the same dependency you have just been bitten by. Fractional HR management exists for exactly this split — a senior person for the judgement, alongside a competent administrator for the records.

The part worth keeping

The uncomfortable truth is that a resignation is the cheapest moment you will ever get to document HR, because the knowledge is still in the building and there is a deadline. Companies that do the extraction properly usually end up better documented than they were before the resignation. Converting those pages into maintained HR documentation afterwards is what stops you being here again when the next person leaves.

And if the extraction exposes that nobody can say which policy version is current — which it usually does — that is worth fixing before the successor arrives, not after. A new HR hire who spends their first year discovering the rules is a year you have paid for twice. Getting the HR process written down first is what lets them run it instead.

What not to do in the first week

Two reflexes are worth resisting. The first is to start recruiting immediately, because the vacancy feels urgent — and every hour spent on a job description in week one is an hour not spent with the person who still holds the knowledge. Recruitment can start in week three; extraction cannot happen later.

The second is to ask her to write everything down alone. A document produced in isolation records what she thinks is important, which is not the same as what you will need. Shadowing produces better material precisely because it captures the things she does without noticing she is doing them.

It is also worth being explicit with her about why. People who are leaving on good terms are usually willing to help, and being told that the aim is to protect her successor from the position she is in — sole holder of everything — tends to produce more candour than a handover form does.

None of this needs to wait for a resignation, incidentally. The same eight or nine pages written while nobody is leaving is simply HR documentation, done calmly, and it is the single thing that makes the next resignation a staffing problem rather than a crisis.
