How to describe confidential work without breaching it

There is a method, and it is not "be vague". Describe the case by its shape and never by its identity.

• Scale, not people. "A twelve-week collective consultation across two sites" tells the reader what you handled. It does not tell them who.
• Outcome, not narrative. "Concluded at stage two, no appeal, no claim" is the fact that matters. The story of what the employee did is not yours to tell.
• What changed afterwards. This is the strongest line available to you and it is not confidential at all: the policy you rewrote, the manager training you ran, the note-taking standard you introduced because the first investigation showed you why it was needed.
• Watch what a small department gives away. "A grievance against a warehouse supervisor in 2025" identifies a person if the warehouse had two supervisors. Round the timeframe, drop the function, or move up a level of abstraction.

One caution worth more than the rest: if you are still employed, your duty of confidence is live while you write. A candidate who names a case at interview has shown the panel exactly how they will talk about this employer at their next one.

Your reader screens letters for a living

In most HR vacancies the hiring manager is an HR director, and applications are their trade. They know that "passionate about people" appears in a third of the pile, that "strategic business partner" is copied from the advert, and that a candidate who lists competencies in the order the posting lists them has done nothing but reformat it. None of that costs you the job on its own. Still, those sentences do no work, and you have one page.

What does work with that reader is a sentence they can picture themselves writing. They have sat with a manager who wanted someone gone by Friday. Show them you have too, and that it did not happen by Friday.

Which HR job is this

The title covers two roles that share almost nothing, and the advert usually tells you which by what it leaves out.

• The solo generalist. Forty to three hundred staff, no HR team, and you own everything: contracts, payroll input, right-to-work checks, absence, the handbook, the difficult conversation and the tea afterwards. An advert that mentions payroll, or a first HR hire, is this one. Lead with breadth, and with the fact that you have written a policy from nothing rather than inherited one. The documents come with the job too: this is the person who issues the appointment letters and drafts the handbook, and nobody else is going to.
• The specialist manager. A thousand staff and up, sitting inside a function, and the job is one slice of it: employee relations, talent acquisition, reward, learning, HRIS. An advert that names a slice and never mentions payroll is this one. Lead with depth and caseload, and resist proving breadth nobody will ask you for.

Getting this wrong is, on the adverts we read, the most common reason a strong HR candidate lands as a poor fit. The generalist who leads with strategy sounds unready for the admin; the specialist who leads with breadth sounds like they will be bored by March.

The paperwork is what a court reads later

HR process looks like administration until someone brings a claim, at which point it is the evidence. That is why procedural work belongs in your letter, and the mechanism is worth knowing exactly.

In the UK the ACAS Code of Practice on disciplinary and grievance procedures is not itself law, but a tribunal may adjust compensation by up to 25 per cent where a party unreasonably failed to follow it. It runs both ways: up to a quarter more against an employer who skipped the steps, up to a quarter less for an employee who did. An HR manager who keeps the process clean is holding down a number with a percentage sign on it.

In the United States the mechanism differs and points the same way. Where a supervisor harasses someone and no tangible employment action follows, Faragher and Ellerth give the employer a defence on two limbs: that it took reasonable care to prevent and promptly correct the behaviour, and that the employee unreasonably failed to use the procedure available. In practice that defence is the policy you circulated, the training you ran, and how fast you acted. Written by HR, months before anyone needed it.

So "I rewrote the grievance procedure and trained forty line managers on it" is not an admin line. Say what it protected. The same holds at the other end of the process, where a badly drafted termination letter is the document a claim gets built on.

The numbers, and the denominators they need

HR metrics travel badly. "Reduced turnover by 20 percent" could be six leavers instead of eight in a team of thirty, which is noise, or a hundred and forty people out of nine hundred, which is a different job entirely. Give the denominator.

Two more distinctions a professional reader will make whether or not you make them first. Regretted turnover is not total turnover, and a manager who cut the wrong-hire kind while the headline held steady has done real work that the headline hides. Time-to-fill belongs next to the vacancy type, because thirty-one days for a warehouse operative and thirty-one days for a qualified accountant are not the same achievement. Where you carry an employee relations caseload, give the volume and the stage most cases closed at. Cases that end early are a sign of an HR function people trust early.

Credentials, and what they are worth

None is legally required to work in HR, and saying so plainly is more useful than the coyness most guides manage. What they do is settle a screening question before the interview.

• CIPD, UK and Ireland. Qualifications run at Levels 3, 5 and 7. Associate membership follows a Level 3 or 5; Chartered Member needs the Level 7 diploma plus at least a year of recent work at an operational or strategic level within the last five years. Adverts often say "CIPD Level 5 or working towards", so if you are mid-study, give the level and the finish date.
• SHRM, United States. Neither the SHRM-CP nor the SHRM-SCP requires a degree, or even an HR job title. The SCP expects around three years of strategic-level HR work, or three years holding the CP.
• HRCI. The PHR wants one year of professional-level HR experience with a master's, two with a bachelor's, four with less than a bachelor's.

Hold none of them and the advert asks? Address it in a clause rather than hoping: the years you have done, and whether you are studying. An employer who wanted the letters and got a candidate who ignored the question assumes the worst.

A worked letter

Sinead is moving out of care, a sector with high turnover and heavy casework, into food manufacturing. Read the second paragraph: every case is anonymised by shape, and the achievement is the thing she changed afterwards.

A blank to work from

Fill the brackets in order. Paragraph two decides this application, so give the casework its shape and spend the words on what you changed after it.
