Objectives <p>Despite a significant proportion of working age adults being estimated to have dyslexia, the relationship between dyslexia traits and workplace cognition has received little direct investigation. The current online survey study investigated subjective workplace cognitive complaints in a final sample of 220 UK professional office workers whose first or second language was English.</p> Methods <p>Self-report questionnaires relating to dyslexia traits and the frequency of workplace subjective cognitive complaints were presented. Self-reported language status, age, mental health, and ADHD symptoms were controlled in a hierarchical regression design. Dyslexia traits were entered in the final model.</p> Results <p>Dyslexia traits positively predicted total score, as well as scores on all subscales (Memory, Language, Executive Function, Speed of Processing, Cognitive Control, and Name Memory). Symptoms of ADHD also positively predicted scores on all subscales except Language and Name Memory. Aspects of subjective cognitive complaints were also positively predicted by age and mental health.</p> Conclusions <p>The findings indicate how self-reported dyslexia traits can predict subjective cognitive concerns in the workplace. Different patterns were found for dyslexia traits and ADHD symptoms, suggesting different workplace cognitive concerns. While based on a community sample, the understanding gained from this study can inform broader support for dyslexic workers, allowing a more nuanced and more general cognitive approach to support.</p>
