In this article, we will describe the impacts of dyslexia on the behaviours of dyslexic workers within their organization. The learning disabilities associated with the invisible disability of dyslexia can lead to situations of stigmatization in childhood, causing wounds, or stigmas, in the individuals concerned, which remain open throughout their lives and which, when revived in an organizational environment, will lead to a response of concealing the disability. To carry out this research, we used life story methodology (Bertaux, 1997) to analyze the results of a 4-year study of 21 people. A research protocol was adapted to this sensitive topic to facilitate the interviewees’ testimony. The results show that dyslexic workers can develop several types of tactics to hide their disability in order to avoid new suffering induced by the revival of their stigma. Thus, our article focuses on how this stigma impacts dyslexic workers in their tactics of disability concealment and disclosure. These tactics have been discussed by Clair et al. (2005) and Jones and King (2014). Our analysis enriches that literature by demonstrating the existence of tactics other than those described by the above two studies, such as the one we call the tactic of disability transfiguration. Our analysis also offers keys to understanding the consequences of having a stigma, for dyslexic workers, with regard to the process of disclosing this disability. Abstract Being affected by dyslexia in the workplace can be a challenge. Already victims of stigmatization during their education because of the disorders caused by this handicap, dyslexic workers deploy strategies to blend in and avoid having their handicap detected in order not to relive these situations of suffering. This research was carried out with the aim of uncovering these strategies of concealment put in place by these workers in order to maintain a positive image with their managers and their team. The researcher is himself dyslexic and can access this sensitive terrain and adopt an auto-ethnographic posture.
