Is "Time Blindness" a valid reason for lateness?

What is Time Blindness?

Time blindness is a common symptom of ADHD (Neurodiversity), where individuals struggle to perceive the passing of time or estimate how long tasks take.

Is it a Disability?

Yes, if your ADHD has a “substantial and long-term adverse effect” on your ability to carry out normal day-to-day activities, it is protected under the Equality Act.

Can I be fired for being late?

Yes. Even if you are disabled, an employer needs you to do the job. If lateness impacts the business (e.g. opening a shop, relieving a colleague), they can discipline you. The “adjustment” is ensuring the discipline is fair and considering alternatives first.

Reasonable Adjustments

1. Flexible Start Window: Instead of “9:00am sharp”, asking for “ensure you arrive between 8:45 and 9:15”.
2. Later Start Time: Moving your shift permanently to 9:30am if mornings are the struggle.
3. Visual Aids: Allowing clocks/timers at the workstation.

Unreasonable Adjustments

• “I will turn up when I get there.”
• “You cannot discipline me for being late.”
