The Rehearsal Dismissal: What a Mock Probation Case Reveals About an SME’s People File

November is rarely quiet for people teams, but this year the pressure is different. The Employment Rights Bill is no longer just a Westminster story. As its measures are commenced in stages, SME owners are being asked to translate broad commitments on day-one unfair dismissal, zero-hours work and flexible working into everyday management practice.

For owners and managers, the useful exercise is not another policy read-through. It is a rehearsal. Pick a plausible hire, walk the file from offer letter to probation review, and see where the paperwork breaks.

Set the scene: one hire, five pressure points

Take a fictional but ordinary SME: a 45-person interiors supplier with a small management team, a busy warehouse and a handful of office staff. It hires Sam as an assistant operations manager on a six-month probation. Sam is on a salaried contract, but the warehouse rota often runs long and Sam is expected to cover early shifts when orders spike.

Within three months, performance is mixed. Sam says the training was patchy. A colleague says Sam was abrupt with a driver. The manager wants to end the probation early. Nothing has been written down beyond a few WhatsApp messages and a rota spreadsheet.

That is the moment to run the rehearsal. A mock dispute is not a legal tribunal in miniature. It is a systems test: does the file tell a coherent story, and would a neutral reader see fairness in the process?

The offer letter and written statement

The first pressure point is the document Sam received before day one. UK employers already need to give a written statement of particulars on or before the first day of employment. Under the changing regime, that document becomes more important, not less, because day-one unfair dismissal rights make the entire recruitment and probation trail relevant.

The rehearsal should test consistency. Does the offer letter match the contract? Does the contract match the rota? If the contract says core hours of 9am to 5pm but Sam has been working 7am to 3pm, the employer has an evidence problem. Tribunals look at reality as well as paperwork.

Check the basics: job title, duties, place of work, pay, hours, holiday, notice, probation terms, training, and any flexibility clause. Then check the less obvious items: who Sam reports to, how performance is measured, and whether the contract reserves the right to change shifts. A vague clause is not a substitute for a clear operating practice.

Probation clauses that survive scrutiny

Probation is not a legal status that suspends employment rights. It is a contractual and procedural tool. If the contract allows probation to be extended, the clause should say how, by whom and by when. If performance concerns are to be addressed in a probation review, the employer needs evidence that the review actually happened.

In the rehearsal, the manager discovers that Sam’s probation was mentioned in the offer letter but no review date was ever set. The HR folder has a template, but it was never completed. The manager’s notes are in a notebook at the warehouse.

That is a common SME gap. The fix is not a longer policy. It is a simple probation timetable: induction checklist, four-week check-in, mid-probation review, final review, and a clear record of what support was offered. If the employer later needs to rely on performance, the file should show a fair opportunity to improve.

Shift patterns and zero-hours exposure

Even where Sam is salaried, the rehearsal should pull in the warehouse rota. The reforms around zero-hours contracts are not confined to businesses that use zero-hours paperwork. If regular staff are effectively working variable hours with little notice, the employer should understand the exposure.

The practical questions are straightforward. Who authorises shift changes? How much notice is given? What happens if a shift is cancelled at short notice? Are regular extra hours recorded, and are they offered consistently? If the business uses zero-hours contracts, are managers aware that guaranteed-hours offers may become part of the regime after a reference period set in regulations?

The answers should be written down. A rota system that works because everyone knows the warehouse manager’s mobile number is not a defensible process. It is a single point of failure.

The manager script: flexible working and the probation review

The third pressure point is the conversation. Flexible working requests must be handled in a reasonable manner, with decisions communicated within the statutory timeframe and refusals based on permitted reasons. Managers need a script, not a slogan.

In the rehearsal, Sam asks to finish at 3pm two days a week to manage a family commitment. The manager’s instinct is to say the business cannot accommodate it. That may be the right outcome, but the file needs the reasoning: the effect on shift cover, whether a trial period was considered, whether duties could be reallocated, and why the refusal reason applies.

The same discipline applies to the probation review. The manager should open with the purpose, set out the evidence, invite Sam’s explanation, ask what support would help, and adjourn if new information emerges. The note should record what was said, not just the conclusion. If Sam asks to be accompanied, the employer should know its policy and apply it consistently.

The dismissal meeting and the file that follows

Suppose the rehearsal ends with dismissal during probation. The employer’s instinct may be that probation makes the decision straightforward. It does not. The employer still needs a fair reason and a fair process, and the day-one unfair dismissal changes make the chronology more important.

The file should answer basic questions. Was Sam told the concern in writing? Was there a meeting? Was Sam allowed to respond? Was there an appeal route? Were the notes dated and retained? If performance was the reason, is there evidence of targets, feedback and support?

A useful test is to hand the file to someone who has never met Sam. Can that person explain why the decision was made and what Sam was told? If the answer relies on the manager’s memory, the file is not ready.

What to fix before the first claim lands

The first sign of a dispute may be an ACAS early conciliation notification, not a tribunal claim. By then, the employer’s file is largely fixed. The rehearsal should produce a short action list, not a rewrite of every policy.

Priorities for November 2026 include: aligning offer letters and contracts with actual shift practice; setting dated probation reviews; recording flexible working requests and refusals; training managers to keep contemporaneous notes; and checking that zero-hours or variable-hours arrangements are understood by line managers, not just HR.

None of this guarantees that a claim will never arrive. It does make the employer’s account more credible. In a regime moving towards day-one rights, the paper trail is not bureaucracy. It is the management system made visible.
