You know that neurodiversity matters. You see where small changes could make a big difference — a training session for managers, a review of recruitment policies, or a dedicated quiet space in the office. You understand how adjustments could improve performance and retention, and how training could reduce risk.

But then you take the idea forward and hear the same line:
“I’ll have to check if budget can be allocated.”

It’s not resistance. It’s hesitation. Senior leaders want reassurance that neurodiversity isn’t just “a nice thing to do” but an investment that protects the business, strengthens culture, and delivers measurable returns.

At Enna, we work with HR, DEI and people managers who face this exact challenge. They’re convinced of the value, but they need help building the case internally. This blog is designed to give you that case — so you can move leadership from “maybe later” to “yes, let’s do it.”

Why Leaders Hesitate

Let’s start with empathy. Budgets are under pressure. Senior decision makers are juggling multiple priorities, compliance, performance, retention, ESG targets, and want to know how each proposal fits into the bigger picture.

When leaders hesitate on neurodiversity, what they often mean is:

• “I can’t see the financial return yet.”

• “I’m not sure how this aligns with our strategy.”

• “We’re already doing diversity — do we need this too?”

The good news: neurodiversity directly supports all of these priorities. The opportunity is to present it in language and evidence that leadership responds to.

The Hidden Costs of Doing Nothing

Before we explore the benefits, it’s worth looking at the costs of inaction. Many organisations already pay a price for not supporting neurodivergent employees, they just don’t see it on a single line in the budget.

• Turnover: Replacing an employee costs 30–200% of their salary. Neurodivergent staff often leave not because of capability, but because they don’t feel supported.

• Tribunal claims: Neurodiversity-related employment tribunals have surged in the past five years. Legal costs, settlements, and reputational fallout can dwarf the cost of proactive training.

• Lost productivity: Every interruption takes an average of 23 minutes to recover from. For neurodivergent employees, constant sensory distractions or unclear expectations multiply that impact.

• Reputation: In competitive sectors, failing to act inclusively affects both employer brand and client trust. Gen Z, in particular, values workplaces that actively support neurodiversity.

The Business Case for Neurodiversity

Here’s the framework we help clients present to leadership. It shows neurodiversity not as an “optional extra,” but as a business-critical investment.

1. Risk Mitigation and Compliance

• The Equality Act 2010 requires reasonable adjustments for employees with disabilities, including many neurodivergent conditions.

• Tribunal cases citing ADHD, autism, and dyslexia are climbing year-on-year. In some cases, damages have reached six figures.

• Proactive audits, training, and clear policies reduce risk, protect compliance, and demonstrate due diligence.

👉 For leadership, this means neurodiversity is as much a compliance issue as health and safety.

2. Retention and Engagement

• Research shows poor inclusion is a leading driver of turnover.

• Many neurodivergent employees don’t disclose their needs because they fear stigma. Quiet attrition follows, they leave silently, taking skills with them.

• Simple adjustments like written instructions, flexible hours, or manager awareness training can dramatically reduce attrition.

👉 Retaining one skilled employee often saves more than the cost of training an entire management team.

3. Performance and Productivity

• Neurodivergent employees bring recognised strengths: creativity, problem-solving, big-picture thinking, and detail orientation.

• Without support, energy is spent masking or coping. With support, that energy is redirected into performance.

• Inclusive teams are proven to be more innovative and productive. McKinsey found diverse teams outperform their peers by 35%.

👉 Neurodiversity is not just about “reasonable adjustments”, it’s about unlocking talent that’s already in the business.

4. Reputation and Competitiveness

• Major organisations like Microsoft, EY, and JPMorgan have public neurodiversity initiatives. They’re not doing it for PR alone, they see the competitive advantage.

• Clients and customers increasingly ask about suppliers’ inclusion practices.

• Talent attraction depends on it. Nearly half of Gen Z identify as neurodivergent or with mental health differences. They want to work where they’ll be supported.

👉 Acting on neurodiversity isn’t just about internal culture, it’s about external brand strength.

Anticipating Leadership Questions

Here’s how we suggest answering the most common objections:

• “We don’t have the budget.”
  The costs of turnover, tribunals, and disengagement are already on your books. Prevention is cheaper than cure.

• “We already do diversity.”
  Without neurodiversity, any D&I strategy is incomplete. At least 1 in 7 employees are neurodivergent — ignoring them means leaving a significant portion of your workforce unsupported.

• “How do we measure success?”
  Impact can be tracked through retention rates, employee surveys, adjustment uptake, and reduced grievances. These are measurable and reportable.

Practical First Steps

Leaders don’t need to commit to everything at once. Many of our clients start small:

• A half-day training session for managers.

• A workplace audit to identify risks and opportunities.

• A pilot in one department before scaling up.

These lower-cost steps demonstrate value quickly, building confidence for wider investment.

Final Thoughts

When you hear, “I’ll have to check if budget can be allocated,” remember: it’s not a barrier, it’s an opportunity. It’s leadership asking for the evidence to say yes.

By showing how neurodiversity protects compliance, strengthens retention, boosts performance, and enhances reputation, you give them that evidence. And with the right partner, you don’t have to build that case alone.

👉 If you’d like support in making the case within your organisation, explore our training for managers or workplace audits. We’d be glad to help.
