How to use AI to write a simple performance improvement…

Failing to document performance issues before termination is one of the top reasons small businesses lose wrongful termination claims, according to SHRM{:target="_blank"} — and most owners have no HR department to catch that gap. This post walks you through using AI to write a performance improvement plan for your small business: a legally defensible, plain-English document tailored to your actual situation. The setup takes under an hour, and a solid PIP can be the difference between a clean separation and a costly tribunal or lawsuit.

What you need before you start

ChatGPT{:target="_blank"} — a conversational AI that drafts structured documents from your specific inputs. The GPT-4o model handles this task well. Pricing: the free tier{:target="_blank"} covers this use case; the Plus plan at $20/month (as of May 2025) gives you faster responses and priority access, but it's not required.

Claude{:target="_blank"} — an alternative from Anthropic that tends to produce cleaner, more neutral prose, which matters for legal documents. The free tier is sufficient; the Pro plan runs $20/month (as of May 2025) if you need higher usage limits.

Time required: 20–30 minutes to gather your notes and run the prompt; another 15–20 minutes to edit the AI draft and format it for signing. Budget an additional 1–2 hours if you're having it reviewed by a lawyer (recommended for your first PIP).

Skill level: No technical background required. You need to be able to describe your employee's role and the specific issues in writing — the more concrete your notes, the better the output.

Why small businesses need a performance improvement plan — and what skipping it costs

The U.S. Small Business Administration{:target="_blank"} reports that 99.9% of U.S. businesses are small businesses, and most have no dedicated HR function. That means the owner is the HR department — which also means the owner carries the legal exposure. Most U.S. states operate under at-will employment, so you can legally terminate without cause. Here's the catch: "at-will" doesn't protect you from a discrimination or retaliation claim. A documented PIP shows the termination was performance-based and that the employee received fair notice — two things a court or tribunal will want to see.

In the UK, ACAS{:target="_blank"} strongly recommends a formal improvement process before dismissal to demonstrate fair procedure under the Employment Rights Act 1996. In Australia, Fair Work{:target="_blank"} guidelines call for documented warnings and improvement plans before dismissal — particularly for businesses with 15 or more employees. The document protects you in all three jurisdictions, and the cost of drafting one with AI is effectively zero.

One critical framing note: a PIP is not a disciplinary notice or a termination warning. It is a structured support document. Written and delivered that way, it reduces defensiveness and gives the employee a genuine chance to improve. Courts and tribunals can also tell when a PIP was written after the decision to fire was already made — don't write one retroactively.

What a simple performance improvement plan template contains

A PIP does not need to be long. One to two pages of plain English, signed by both parties, is legally sufficient in most jurisdictions. The five elements that matter:

The performance gap — a factual, neutral description of the specific behavior or output that falls below standard, with dates and examples where possible.
Measurable goals — what "good" looks like in this role, stated in observable terms: on time 95% of shifts, zero customer complaints per week, 10 units processed per day.
Timeline — 30, 60, or 90 days is standard. Thirty days is common for attendance or conduct issues; 60–90 days for skill or output gaps that need time to develop.
Support the employer will provide — training, additional supervision, clearer instructions, equipment. This element is what distinguishes a support document from a paper trail.
Consequences if targets are not met — stated plainly and without threats. "Failure to meet the targets above may result in further disciplinary action, up to and including termination."

Before you open AI: the information to gather first

The quality of an AI-drafted PIP is entirely dependent on what you put into it. Vague inputs produce generic outputs that won't reflect your actual situation and won't hold up if challenged. Write down the following before you open any AI tool:

The employee's job title and their three to five main responsibilities
Specific incidents or patterns, with dates where you have them ("Three late arrivals in October: the 4th, 11th, and 19th")
What good performance looks like in this role — concrete and measurable
What support or feedback you have already provided, and when
The timeframe you want for the plan: 30, 60, or 90 days
What happens at the end of the plan if targets are not met

This takes 10–15 minutes and makes the difference between a document that sounds like it was written for someone else and one that actually describes your employee's situation.

How to prompt AI to write your performance improvement plan

The prompt structure below works in ChatGPT (GPT-4o) and Claude. Paste it in, fill in the bracketed fields with your specific notes, and run it.

Prompt:

I am a small business owner without an HR department. I need to write a simple, professional performance improvement plan (PIP) for an underperforming employee. Please draft a one-to-two-page PIP using the information below. Use neutral, factual, constructive language only — no threats, no emotional language, no assumptions about why the employee is underperforming.

Employee role: [e.g., Barista at a café / Retail sales assistant / Apprentice electrician]

Main responsibilities: [List 3–5 key duties]

Performance issues (be specific): [e.g., Late to shifts on 4 occasions in October; received two written customer complaints in September regarding poor service]

What good performance looks like: [e.g., On time for all scheduled shifts; no more than one customer complaint per quarter; completes closing checklist without reminders]

Support already provided: [e.g., Verbal warning on October 10th; additional training on coffee machine maintenance on September 15th]

Support the business will provide during this plan: [e.g., Weekly check-ins with manager; updated opening/closing checklist]

Plan duration: [30 / 60 / 90 days]

Consequence if targets not met: [e.g., Further disciplinary action, up to and including termination of employment]

Format the document with: an introduction paragraph, a table of measurable goals and check-in dates, a section on employer support, and a signature block for both parties.

You should receive a structured draft within 30–60 seconds. The output will be generic enough to need editing — that's expected — but it will have the correct structure and neutral tone to work from. A PIP for a café barista should read differently than one for a tradesperson's apprentice; the AI will reflect those differences if your inputs are specific enough.

Editing the AI draft: what to check before you sign it

The AI draft is a starting point, not a finished document. Before you print it and schedule the meeting, check these five things:

Replace any generic language with your specifics. If the AI wrote "failure to meet performance standards," replace it with the actual incidents and dates you provided.
Verify the goals are measurable. "Improve attitude" is not a measurable goal. "Respond to all customer requests without raising voice or using dismissive language" is.
Remove any language that sounds like a threat or assumes intent. Phrases like "your continued lack of effort" or "your failure to take this role seriously" are legally and practically counterproductive. The AI should have avoided these if you instructed it to — but check.
Confirm the timeline is realistic. A 30-day plan to fix a complex skill gap is setting the employee up to fail — which looks bad for you if it ends in termination.
Add your business name, the employee's name, and the issue date. AI outputs often leave these as placeholders.

How to deliver the PIP and run check-ins

Deliver the PIP in a private meeting. Give the employee a copy to read before they sign — don't demand a signature in the same breath as handing them the document. Explain that this is a support plan, not a termination notice, and that you want to see improvement. For a 30-day plan, schedule weekly check-ins. For 60–90 day plans, bi-weekly is standard. After each check-in, send a brief email summary — even two or three sentences — and keep a copy. That email trail is your contemporaneous documentation if the situation escalates.

A 2023 Gallup study found that only 26% of employees strongly agree their manager helps them set performance goals. A structured check-in against a written plan directly addresses that gap — and it works in your favor whether the outcome is improvement or eventual termination.

Legal guardrails before you sign anything

AI-generated documents are not legal advice. For your first PIP, have a local employment lawyer or HR consultant review the final draft before you issue it. Many offer flat-fee document reviews in the $200–$300 range — that's a reasonable cost to confirm the document is compliant with your local employment law. If you're in the UK, cross-check the structure against ACAS guidance. If you're in Australia, review it against Fair Work requirements before issuing. Do not skip this step for your first plan; once you've had one reviewed and understand what compliance looks like in your jurisdiction, subsequent PIPs are lower risk to draft and issue yourself.

When something goes wrong

The AI draft sounds generic and doesn't reflect your employee's actual situation. Root cause: your inputs were too vague. Go back and add specific dates, incidents, and measurable descriptions of what good performance looks like in this role. Rerun the prompt with those specifics — the output will be materially different.

The goals in the AI draft aren't measurable. Root cause: the AI defaulted to soft language because your brief didn't define clear metrics. Add a sentence to your prompt: "All goals must be measurable and observable — no subjective language." You can also ask the AI to rewrite any goal that uses unmeasurable terms.

The employee refuses to sign. This happens. The honest answer is that a signature is preferred but not required for the document to be valid. Note in writing (to yourself, dated) that the employee declined to sign, and proceed with issuing the plan regardless. The refusal itself is a documented fact.

What to do next

Once you've issued the PIP and started check-ins, document each conversation with a brief email summary. If the plan period ends and performance hasn't improved, that documentation chain is what makes any subsequent action defensible. If you handle payroll or employment admin manually, it's also worth looking at whether a simple HR workflow could automate the reminders for check-ins.

If you're managing recurring admin tasks like this manually, using AI to automate small business admin workflows is worth exploring next.

FAQ

How do I write a performance improvement plan for a small business without an HR department? Gather notes on the specific incidents, dates, and what good performance looks like in the role. Paste that information into the prompt structure in this post and run it in ChatGPT or Claude. You'll have a structured draft in under five minutes; editing and formatting to a sign-ready document takes another 15–20 minutes.

Does a performance improvement plan template need to be a certain length to be legally valid? No. In most U.S., UK, and Australian jurisdictions, a one-to-two-page plain-English document signed by both parties is sufficient. Length is not a proxy for legal defensibility — specificity and accuracy are.

Can I use a free AI tool to write a PIP, or do I need a paid plan? The free tiers of ChatGPT and Claude both handle PIP drafting without issue. You don't need a paid plan unless you're running high volumes or need priority access. Pricing verified May 2025 — check each tool's site, as these change.

What does it cost to get an AI-drafted PIP reviewed by a lawyer? Most employment lawyers and HR consultants offer flat-fee document reviews in the $200–$300 range for a single document. Some HR consultants charge less. That's a one-time cost for your first PIP; once you understand what compliance looks like in your jurisdiction, the need for external review on routine plans decreases.

What if the employee improves during the PIP period — do I need to document that? Yes — document that too. A brief written note or email at the end of the plan period confirming the employee met their targets closes the loop professionally and protects you equally well. It also matters for the employee's record if future issues arise.
