Sick Note While on Probation: Your UK Rights & Pay

Starting a new job is an exciting but naturally stressful milestone. You are focused on making a brilliant first impression, learning new systems, and integrating into a new team. However, falling ill or suffering an unexpected injury during your probationary period can cause intense panic. Many new employees worry that taking a single sick day during probation will lead to immediate dismissal, or that they have no right to sick pay. The psychological pressure to "work through" an illness during probation is immense, yet doing so can compromise your health and your performance.

In the UK, the concept of a "probationary period" is widely misunderstood. While employers use probation to assess a new hire's suitability, your statutory employment rights are determined by UK law, not by your employer's internal labels. In this comprehensive guide, we will clarify the legal reality of probationary periods, explain your statutory rights to sickness absence and pay, outline why employers enforce strict medical evidence rules for probationers, and show how securing a professional medical certificate is crucial to protecting your new position.

The legal reality of probationary periods in the UK

The first and most important truth to understand is that a "probationary period" has no distinct definition in UK statutory employment law. The law does not recognize a "probationary employee" as having fewer statutory rights than a "permanent employee." Sickness rights, health and safety protections, and discrimination laws apply to you from your very first day of employment.

Probation is entirely a contractual concept. It is an agreement between you and your employer, typically lasting 3 to 6 months, during which both parties can terminate the contract with a shorter notice period (often 1 week instead of 1 month or more). It allows the employer to evaluate your performance and conduct before confirming you in the role.

However, the real legal barrier for new employees is not the probationary period itself, but the length of service threshold for claiming ordinary unfair dismissal. In England, Scotland, and Wales, you must have two years of continuous service with an employer before you can claim ordinary unfair dismissal. Consequently, during your first two years (which includes your probation), an employer can legally dismiss you far more easily, without needing to prove a fair capability process, provided the dismissal is not discriminatory or automatically unfair.

Despite this, employers must still follow their own contractual procedures. If your employment contract outlines a specific sickness or capability procedure that applies during probation, your employer is legally bound to follow it. Failing to do so can result in a claim for breach of contract.

Sickness absence during probation: What are your rights?

If you fall ill during your probation, you have the exact same right to take time off to recover as any other employee. You cannot be legally forced to work if you are medically unfit to do so. However, because you are within the two-year qualifying period, taking excessive or undocumented sick leave during probation carries significant practical risks.

An employer monitoring a new hire during probation is looking for reliability, professionalism, and capability. If you take multiple sick days without providing clear communication or robust medical evidence, the employer may conclude that you are unreliable or lack the capability to perform the role, leading them to terminate your contract at the end of the probation period.

To minimize this risk and protect your professional reputation, you must handle sickness absence during probation with absolute transparency and rigorous compliance. This means:

• Strict notification compliance: You must contact your manager as early as possible on the first day of your illness, following the exact reporting procedure outlined in your handbook. Never rely on a casual text message or ask a colleague to pass on the message; make formal contact directly.
• Over-communicating: Keep your manager updated on your recovery and expected return date, demonstrating that you respect the operational impact of your absence.
• Presenting immediate medical evidence: Do not rely on the standard 7-day self-certification rule unless your contract explicitly permits it. Presenting an independent, professional medical certificate from day one demonstrates that your absence is legitimate and that you treat your employment seriously.

Do you need a sick note from day one during probation?

Under standard UK statutory rules, employees are not required to provide a doctor's sick note for the first 7 calendar days of an illness. They can "self-certify" their absence using a statutory form or an internal company procedure.

However, because probationary periods are governed by contract, employers are legally entitled to write stricter evidence requirements into your employment agreement. It is incredibly common for UK employment contracts to include "probationary clauses" that explicitly bypass the 7-day self-certification rule.

These clauses frequently state that during your probationary period, you must provide a valid medical certificate signed by a GMC-registered doctor for any sickness absence, starting from the very first day of illness. Employers enforce this rule to deter casual absences and ensure that any time off is verified by a clinical professional.

If your contract includes this day-one medical certificate requirement, you are contractually obliged to comply. Failing to present a doctor's note can result in your sick pay being withheld, your absence being recorded as unauthorized, and can trigger disciplinary proceedings that lead to dismissal.

Securing a day-one doctor's note through your local NHS GP clinic is practically impossible. NHS GP practices are severely backlogged and are legally discouraged from writing fit notes for absences under 7 days, as these fall outside standard NHS general medical services. This leaves new employees in a stressful trap: their contract demands a note, but their NHS GP refuses to write one. In Section 7, we will explain how online private services safely solve this bottleneck.

Statutory Sick Pay (SSP) eligibility during probation

A very common source of worry for new hires is whether they are entitled to receive sick pay if they fall ill during probation. It is a widespread myth that sick pay is a privilege reserved only for permanent staff.

Under UK statutory rules, your right to receive Statutory Sick Pay (SSP) is active from your very first day of employment. Sickness during probation does **not** disqualify you from SSP, provided you meet the standard statutory criteria. To qualify for SSP, you must:

• Be classed as an employee: You must have an employment contract (which you do from day one of probation).
• Meet the earnings threshold: You must earn an average of at least £123 per week (before tax) with your employer.
• Satisfy the waiting days: SSP is only paid from the fourth consecutive day of illness. The first three days are classed as "waiting days" and are unpaid under statutory rules, unless you have previously received SSP for a linked absence within the last 8 weeks.

If you meet these criteria, your employer is legally obliged to pay you SSP, currently £116.75 per week, for up to 28 weeks. They cannot withhold SSP simply because you are on probation, or because they have not confirmed you in the role yet.

It is crucial to distinguish between Statutory Sick Pay (SSP) and "company sick pay" (also known as occupational or contractual sick pay). Company sick pay is an optional benefit where an employer pays you your normal full salary while you are off sick. Many UK companies have policies that exclude employees on probation from company sick pay, meaning you will only receive the statutory minimum (SSP) if you fall ill. Make sure you review your contract or company handbook to understand your specific pay structure.

For part-time or flexible workers, understanding these rules is particularly important. You can check our detailed guide on can part-time and zero-hour workers get sick notes to understand how SSP is calculated for non-traditional shift patterns.

Can your probationary period be extended due to sickness?

If you are off work on sick leave for a significant portion of your probationary period, your employer may struggle to evaluate your performance fairly. In these scenarios, it is standard practice in the UK for employers to formally extend your probationary period.

Extending a probationary period is legally permissible, provided the employer has the contractual right to do so (most contracts include a clause allowing for an extension of up to 3 or 6 months). The extension must be confirmed to you in writing before your original probation end date, detailing the reasons for the extension and the new end date.

It is important to view a probation extension not as a disciplinary punishment, but as a supportive measure. The extension gives you a fair opportunity to recover fully, return to work, and demonstrate your capability and skills over a complete, uninterrupted period, ensuring that your suitability is assessed fairly.

However, the extension must be managed reasonably. Your employer should meet with you formally to discuss the extension, outline what performance targets or support will be put in place during the extended period, and document the agreement clearly to prevent any future disputes.

Frequently Asked Questions

Do I need a sick note from day one during a probation period?

Under statutory rules, you can self-certify for the first 7 days. However, most UK employment contracts contain specific clauses requiring probationary employees to provide a doctor's sick note from the very first day of absence. Review your contract carefully, as failing to comply can result in pay being withheld and contract termination.

Am I entitled to Statutory Sick Pay (SSP) while on probation?

Yes. Your right to Statutory Sick Pay (SSP) is active from your first day of work. If you have an employment contract and have done some work under it and are off sick for 4 or more consecutive days, your employer is legally required to pay you SSP. They cannot withhold it simply because you are on probation.

Can my employer sack me for taking a sick day during probation?

Because you have less than two years of service, your protection against ordinary unfair dismissal is limited, and your employer can terminate your contract with short notice. However, they cannot dismiss you for a reason related to a protected characteristic (such as a disability) or for exercising your statutory rights, as these protections are active from day one.

Can my probationary period be extended because of sickness absence?

Yes. If sickness absence prevents your employer from assessing your suitability, they can legally extend your probationary period (typically by 1 to 3 months), provided your contract allows for an extension. The extension must be confirmed to you in writing before your original probation period ends.

Does company sick pay apply to employees on probation?

Company sick pay (paying your full salary during sickness) is a contractual benefit, not a statutory right. Many UK companies explicitly exclude employees on probation from company sick pay, meaning you will only receive the statutory minimum (SSP) during your probation. Check your handbook for details.

Need a medical certificate?

If you need signed medical evidence for work, study, or administrative purposes, you can request a private medical certificate online from a GMC-registered doctor, usually issued within 2 hours during business hours. See the one-off pricing and how private medical certificates work before you start.
