Probation periods are designed to help employers assess whether a new employee is the right fit for a role. They provide an opportunity to review performance, offer feedback and decide whether someone should continue in the position.

But probation periods can sometimes raise more complex questions when neurodivergence is involved.

A new starter might be struggling with workload, communication, organisation or workplace expectations. Managers may be unsure whether the issue is performance, onboarding, or whether something else is getting in the way.

This can lead to an important question for many HR teams:

Do reasonable adjustments apply during probation periods?

The answer is yes. Under the Equality Act 2010, protection from disability discrimination begins from day one of employment, and that includes neurodivergent conditions such as ADHD, autism, dyslexia and dyspraxia.

For employers, this means probation periods should still involve thoughtful consideration of support, communication and workplace barriers.

When this happens early, organisations often discover that what looked like a performance issue was actually a simple adjustment waiting to be made.

Why probation periods can be challenging for neurodivergent employees

Starting a new job involves a huge amount of change. New systems, new colleagues, new expectations and often a lot of information to absorb quickly.

For many neurodivergent employees, this transition can feel particularly intense.

Common challenges during probation include:

• Unclear instructions or expectations
• Fast-paced onboarding processes
• Learning multiple systems at once
• Busy or distracting environments
• Social expectations within teams
• Informal communication styles

These challenges don’t necessarily reflect capability. In many cases they reflect a lack of structure or clarity.

For example, a neurodivergent employee may perform extremely well once they understand how the role works. But if instructions are vague or priorities constantly shift, it can be difficult to get started.

The good news is that many of these barriers are relatively simple to address.

Do reasonable adjustments apply during probation?

One of the most common misconceptions we hear from employers is that reasonable adjustments only apply once an employee has passed probation.

This isn’t how the law works.

If an employer knows, or could reasonably be expected to know, that an employee has a disability, they may have a duty to consider reasonable adjustments. This applies regardless of whether someone has been in the role for one week or ten years.

In practice, reasonable adjustments during probation often focus on clarity, communication and structure.

Examples might include:

• Providing written instructions alongside verbal ones
• Offering more regular check-ins with managers
• Breaking larger tasks into smaller steps
• Allowing additional time to learn systems
• Sharing meeting agendas in advance
• Clarifying expectations around deadlines and priorities

Many of these changes are small, but they can significantly improve how someone settles into a role.

Disclosure during probation: what if an employee shares a diagnosis?

Another situation that sometimes arises is when an employee discloses neurodivergence during their probation period.

This can occasionally make managers nervous, particularly if performance concerns have already been raised.

However, disclosure should usually be viewed as a positive step. It often signals that the employee wants to explain what support might help them perform at their best.

When a disclosure happens, employers should consider:

• What barriers the employee may be experiencing
• Whether adjustments could help remove those barriers
• How expectations and communication can be clarified

In many cases, simply having an open conversation can resolve issues quickly.

Before ending employment: questions employers should ask

If a probation period is not progressing well, it is worth taking a moment to step back and look at the wider picture.

Some helpful questions to consider include:

Have expectations been clearly communicated?

New starters often struggle when instructions are informal or constantly changing. Providing clear priorities can make a significant difference.

Have potential workplace barriers been explored?

Sometimes a performance concern is actually linked to something practical, such as information overload or unclear processes.

Have reasonable adjustments been considered?

Even small adjustments can transform how someone performs in a role.

Has the employee been given time and support to improve?

Many employees settle into roles once they fully understand expectations and systems.

Taking time to ask these questions doesn’t mean lowering standards. Instead, it helps employers ensure that decisions are fair and based on the full picture.

Why early support benefits employers too

Supporting neurodivergent employees during probation isn’t just about compliance with employment law.

It can also bring significant benefits to organisations.

Many neurodivergent individuals bring strengths such as:

• Creative problem solving
• Strong analytical thinking
• Attention to detail
• Innovative approaches to challenges
• Deep focus on areas of interest

However, these strengths often become most visible once the employee feels comfortable and understands how to navigate the workplace.

Early support can therefore improve retention, reduce recruitment costs and help organisations build stronger, more diverse teams.

Creating a supportive probation process

Organisations that take a neuroinclusive approach to probation periods often focus on a few key principles.

Clear expectations

Employees should understand what success looks like in the role. This includes priorities, deadlines and key responsibilities.

Structured feedback

Regular check-ins allow managers to identify challenges early and provide guidance before issues escalate.

Open conversations

Encouraging employees to discuss what support helps them work effectively can make adjustments easier to implement.

Consistent documentation

Keeping clear records of feedback and discussions ensures that any decisions made later are well supported.

When these elements are in place, probation periods become less about catching mistakes and more about helping people succeed.

A growing focus on neuroinclusive workplaces

As awareness of neurodiversity continues to grow, many organisations are recognising that traditional workplace practices do not always suit everyone.

Probation periods are a good example of where small changes can have a meaningful impact.

When employers combine clear expectations with a willingness to consider adjustments, they often find that employees who initially struggled go on to perform extremely well.

Ultimately, creating a fair and supportive probation process benefits both employees and organisations.

Supporting managers to navigate neurodiversity

Many managers want to support neurodivergent employees but feel unsure about how to approach conversations around performance, adjustments or disclosure.

At Enna, we work with organisations to build confidence in these situations through neurodiversity training, practical guidance on reasonable adjustments and support for managers navigating complex workplace scenarios.

Our aim is to help organisations create workplaces where expectations are clear, support is available and neurodivergent employees have the opportunity to thrive.
