Navigating Probation Periods in Today’s Workplace: A Practical Guide for UK Employers

As the UK employment landscape gears up for a major shift with the new Employment Rights Bill, probation periods are more important than ever. This Bill, introduced in October 2024, includes a transformative change: day-one protection from unfair dismissal, set to come into force in Autumn 2026. With these new rights, probation periods will become an essential focus for employers to ensure both compliance and a good start for every new hire. But probation should be more than a legal safety net; it’s an opportunity to set up both employers and employees for long-term success.

So, what does a probation period look like in this new context, and how can we make it work in everyone’s favour?

What is a Probation Period Really For?

Think of probation periods as the ultimate “getting to know you” phase. This isn’t just about checking boxes on performance targets; it’s about assessing alignment between the employee, the role, and the culture. At its core, a probation period is about setting expectations and ensuring a strong start.

  • For employers: Does the new hire align with the team’s needs and company values? Are they adapting well to the role?
  • For employees: Does the job match their expectations? Do they feel equipped and supported to succeed?

Despite its benefits, probation isn’t legally required, though it’s a best practice for UK employers who want to optimise their onboarding, minimise risks, and establish a solid foundation with each new team member.

Why Probation Periods Matter More Than Ever

With day-one unfair dismissal rights on the horizon, probation periods will become a pivotal tool. Under current law, employees with less than two years of service generally can’t claim unfair dismissal, allowing employers some flexibility in addressing performance issues early. The new Bill, however, will mean that dismissing an employee, even in their first months, requires a careful approach. Probation periods, when structured effectively, help ensure that decisions made early on are fair, transparent, and compliant.

The bottom line? A probation period should be a structured trial that adds value and creates a clear framework for assessing fit—so that decisions are mutually beneficial.

Setting Up a Successful Probation Period

Bringing someone new into your business? Here’s how to set up a probation period that drives value and builds a positive, lasting relationship:

  1. Define Expectations from Day One: Be transparent about role responsibilities, performance standards, and key deliverables. Make it clear to new hires what’s expected and why it’s important.
  2. Plan Regular Check-Ins: Schedule one-to-one meetings to review progress, answer questions, and provide actionable feedback. Regular support can prevent small issues from becoming larger problems and helps new hires feel valued.
  3. Invite Open Dialogue: Remember, probation is about mutual fit. Encourage new hires to share how they’re finding the role and adapt where appropriate to support success.
  4. Address Concerns Early: If issues arise, don’t wait until the end of the probation period to provide feedback—issues are best addressed in real-time, with clear guidance on expectations.

Determining the Right Length for a Probation Period

The length of a probation period often depends on the role’s complexity and seniority. In the UK, three to six months is standard. Anything longer than six months might be excessive unless there’s a clear, valid reason. The Good Work Plan requires that probation terms (including length) be outlined in the employment contract, so precision is crucial.

For particularly complex roles, starting with a six-month probation but allowing for an early confirmation can create a motivational boost for new hires. This flexibility not only encourages high performance but reinforces a positive working relationship.

Extending Probation Periods: When and Why?

Extending a probation period should be a last resort, yet sometimes it’s necessary if an employee shows potential but hasn’t quite met all requirements. When extending, clearly explain the reasons and areas for improvement. Document the agreed-upon goals, and set a new review date to maintain focus.

Common Reasons for Extending Probation Periods Include:

  • Continued performance improvement needed
  • Conduct or behaviour issues
  • Frequent absences or attendance issues
  • Delays in meeting role-specific targets
  • Ongoing punctuality problems

Any extension should be reasonable, documented, and consistent with the terms outlined in the employment contract.

Successfully Completing Probation: What’s Next?

When an employee passes their probation period, it’s more than just a confirmation of employment. This is the time to formally welcome them as a valued member of the team and to outline the new benefits and responsibilities that come with the role. Proactively scheduling a formal review meeting helps avoid the risk of “passing by default,” a common issue where probation ends without an official decision.

What to Cover in This Meeting:

  • Celebrate their achievements and formally confirm their role.
  • Review any new entitlements, such as additional benefits or pension contributions.
  • Outline any additional responsibilities or long-term performance goals.

What Happens If an Employee Doesn’t Pass?

If a new hire doesn’t meet expectations, employers generally have two options: extend the probation period or part ways. When termination is the final decision, approach it with empathy, transparency, and respect. The goal should be to leave the employee with constructive feedback, making the transition as smooth as possible.

Here’s how to handle it:

  1. Schedule a Final Meeting: Clearly explain the decision and provide specific, constructive feedback. Keep the conversation professional but compassionate.
  2. Document the Outcome: Follow up with written confirmation of the decision to ensure clarity and prevent future issues.
  3. Provide Transition Support: Where possible, offer a referral or guidance for next steps. A positive, supportive exit can lead to constructive experiences and maintains your organisation’s reputation.

Probation Periods for Promotions: Do They Work?

When promoting an existing employee, it’s sometimes appropriate to implement a probation period, especially for senior roles with new responsibilities. This approach allows employers to assess the employee’s suitability in the new role. However, for employees with two years or more of service, failing a probation period after promotion could involve an option to return to a previous role or claim unfair dismissal if dismissed without just cause. This makes transparency and clear expectations all the more critical.

Conclusion: Building an Effective Probation Period Process

Probation periods are powerful tools that, when used effectively, establish mutual expectations and foster long-term success. By creating a well-structured, communicative probation period, employers can build positive, lasting relationships with new hires and avoid potential pitfalls as UK employment law continues to evolve.
