You know neurodiversity matters. You can see where small changes would make a big difference: a training session for managers, a review of recruitment, a quiet room in the office. You know adjustments would help performance and retention, and that training would cut risk.
Then you take the idea upstairs and hear the familiar line: “I’ll have to check whether budget can be allocated.”
That usually isn’t a no. It is hesitation. Senior leaders want to know that neurodiversity is an investment that protects the business, strengthens culture and pays back, rather than a nice thing to do.
We work with HR, inclusion and people leads in exactly this position. They are convinced; they need help making the case. This post sets out that case so you can move leadership from “maybe later” to “yes”.
Why leaders hesitate
Budgets are under pressure and senior teams are juggling compliance, performance, retention and ESG targets. When they hesitate on neurodiversity, they often mean one of three things:
- “I can’t see the financial return yet.”
- “I’m not sure how this fits our strategy.”
- “We already do diversity. Do we need this as well?”
Neurodiversity supports all of those priorities. Your job is to show it in the language and evidence leadership already uses. If the topic keeps being deferred, our post on why neurodiversity slips off the strategic agenda may help you diagnose why.
Start with the cost of doing nothing
Most organisations are already paying for not supporting neurodivergent employees. It just isn’t labelled that way.
Turnover. Replacing someone means recruitment fees, onboarding time and months of lost productivity. Neurodivergent people often leave because the support they needed never came, not because they couldn’t do the job.
Tribunal claims. HM Courts and Tribunals Service recorded 265 employment tribunal cases involving neurodivergent conditions in 2020 and 517 in 2025, according to analysis by Irwin Mitchell. Awards can be large: one recent ADHD probation dismissal case cost a hotel employer around £200k.
Lost productivity. Noisy offices, vague instructions and rigid processes drain energy that could go into the work.
Reputation. In competitive sectors, a poor record on inclusion affects both your employer brand and client trust.
We go deeper on each of these in the hidden cost of ignoring neurodiversity.
The business case in four parts
1. Risk and compliance
The Equality Act 2010 places a duty to make reasonable adjustments on employers, and many neurodivergent employees will meet the Act’s definition of disability. Audits, training and clear policies reduce risk and show due diligence. Put simply for leadership: this belongs alongside health and safety, not in the optional pile.
2. Retention and engagement
Many neurodivergent employees never disclose because they fear stigma. Instead they leave quietly and take their skills with them. Simple adjustments such as written instructions, flexible hours and trained managers keep people. Retaining one skilled employee can save more than it costs to train a whole management team.
3. Performance
Many neurodivergent people bring creativity, problem solving, big picture thinking or close attention to detail. Without support, energy goes on masking and coping. With support, it goes into the job. This is about getting the most from talent you already employ.
4. Reputation and competitiveness
Large employers such as Microsoft and JPMorgan Chase have run neurodiversity hiring programmes for years because they see the advantage. Clients increasingly ask suppliers about inclusion, and candidates notice which employers walk the talk.
Answering the common objections
“We don’t have the budget.” The costs of turnover, claims and disengagement are already on your books. Prevention is cheaper.
“We already do diversity.” A diversity strategy that leaves out neurodiversity is incomplete. A widely cited estimate puts neurominorities at around 15 to 20 percent of the population, which is a large share of any workforce.
“How will we measure success?” Track retention, survey scores, adjustment requests and resolution times, and grievances. Our post on which neuroinclusion metrics matter has a starter set.
Ask for a small first step
Leaders don’t have to commit to everything at once. Many of our clients start with a half day manager session, a short audit, or a pilot in one department. Lower cost steps show value quickly and build confidence for wider investment.
How Enna can help
We can help you build the case as well as deliver the work. That might mean a short business case summary for your leadership team, or joining a meeting to answer questions directly. Our neurodiversity session for senior leaders is designed to turn interest at the top into commitment.
For a low risk pilot, our Neurodiversity Foundations for Managers workshop gives you results to report back. If you need data first, our free neuroinclusion maturity assessment or a full neuroinclusion audit gives you a baseline leaders will recognise. Book a call and we’ll help you plan the conversation.
