Dignity is a human right and a base for human health. This right must be observed in work environments as a moral obligation. This qualitative study aimed to understand nurses' experiences of violation of their dignity at work and to explore its dimensions. The participants were 15 nurses working in two hospitals in Tehran. The data were collected through 26 unstructured interviews and analyzed using content analysis. The dimensions of violation were 'irreverence', including experiences of abuse and violence, humiliation, and being ignored; 'coercion and violation of autonomy', consisting of the control of relationships, lack of privacy, rigidness, and imposition; 'ignoring professional and scientific ability', indicating impossibilities in applying nurses' knowledge; and 'denying the value of nurse/care', being the theme that verified the dominance of treatment/cure and lack of recognition of care value. Health systems should take the promotion of the nurses' dignity into account through providing a dignified work environment.
