The first weeks of a new job set the tone for everything that follows. They shape how quickly someone finds their feet, how safe they feel asking questions, and whether they start building the relationships that turn a new hire into a committed colleague. Yet much of what we call onboarding still assumes a single, standard way to process information and read a room. When we look closely at what happens to people who do not fit that assumption, we learn something useful about onboarding for everyone.
For many new starters, the early days are where quiet strain builds. That strain is sharpest for neurodivergent employees, but it is more common than most organisations realise. According to the 2025 Neurodiversity Index Report, 41% of neurodivergent workers face workplace challenges in their first few days, and around 35% say they received no onboarding support.
The harder truth is that most of this need is invisible to the organisation. Only 39% of employees with disabilities have disclosed to their manager, and even fewer have disclosed to their teams and HR. In one large study, research conducted by the Society for Human Resource Management (SHRM) revealed that nearly half (47%) of employees with invisible disabilities have not disclosed their conditions to their employers. Similarly, Gallup reports that 37% of employed neurodiverse individuals choose not to share their condition with coworkers, feeling that peers and leaders will stigmatise their natural ways of thinking, feeling and behaving.
This creates a design problem, not just an accommodation problem. If a large share of people who could benefit from support will never ask for it, then a system built around "ask for help" quietly fails them. As Training Industry notes, the cost is real: people hold back even when support would help them succeed; they are forced to adapt to fit the workplace, and they hide parts of how they think and work to fit in, a practice known as masking that takes energy and shifts focus away from the job itself.
The shift worth making is from individual accommodation to universal design. The United Nations Department of Economic and Social Affairs describes universal design as a framework that ensures environments, products, and systems are usable and accessible to everyone; it originated in architecture and education, where the goal was to design spaces and tools that support all individuals without special adjustments. Applied to work, universal design encourages organisations to adapt work itself, making flexibility, accessibility, and choice part of everyday practice.
The elegant part is that support built in for the few tends to lift the many. This is a long-established insight in inclusive design: features created to support some people often make experiences better for everyone. A clear first-week plan, plain-English materials and a named person to ask "silly" questions help the anxious graduate, the parent returning from leave, the person who speaks English as a second language, and the confident hire having a rough week. As the Everway team puts it, organisations that build neuroinclusive environments often see engagement increase when people feel safe bringing their whole selves to work, and retention improve because employees are more likely to stay where they feel understood and supported.
If you already invest in a strong start, this connects naturally to creating a sense of belonging from day one and to your first 90 days design. Neuro-inclusive thinking does not replace that work. It sharpens it.
You do not need a dedicated programme to start. Three areas offer the most immediate return, and each benefits every new starter.
1. Make materials accessible by default. Offer information in more than one format rather than a single dense handbook. Everyone processes information differently, so provide materials in written, visual and auditory formats, make sure they are compatible with assistive technologies, and use clear layouts, readable fonts and captioned videos. The key move is to make helpful tools available to all. Making assistive technology available to everyone by default means everyone has the tools to succeed, and no one feels singled out for needing support.
2. Say the unwritten rules out loud. Every workplace runs on norms nobody wrote down, and decoding them silently is exhausting. One of the biggest onboarding mistakes is assuming people will pick things up as they go; many do pick up more than employers realise through observation and informal chats, but when expectations are mostly unwritten, some employees are placed at a disadvantage. A simple "how we work here" guide covering communication channels, response-time expectations and meeting etiquette solves this. As Divergent Thinking observes, clear expectations are not only more inclusive; they are more efficient.
3. Build flexible, choice-based pacing. Front-loading everything into week one overwhelms people. Many new starters get too much information too quickly, with policies, systems, acronyms, introductions, compliance training and process details all piled into the first few days, and that can be hard for anyone. Stagger the load, set explicit milestones and let people choose how they demonstrate progress. The organising principle is choice: let people work in ways that suit how they process information. Pairing new hires with a buddy whose role is to answer questions, not to evaluate, protects people during the highest-risk period. Consider linking this to in-the-moment feedback so early check-ins feel supportive rather than judgemental.
The most important reframe here is that clarity, structure and accessible information are not niche concessions. They are simply better onboarding. As Training Industry puts it, by designing for neuroinclusion you aren't just supporting a minority; you are building a more efficient, creative and human workplace for everyone.
Treated as a one-off exception, this becomes another individual request that most people never make. Treated as design, it becomes an organisational capability: a standard way you welcome people that quietly removes barriers, protects the confidence of every new starter, and turns the first weeks into a foundation for engagement, productivity and retention rather than a hurdle to survive.
So here is the question worth taking back to your team: if a capable new starter never told you what they needed, would your current onboarding still set them up to succeed? If the honest answer is "only if they ask", that is where your next improvement lies.
