The purpose of our article is to present a series of five studies on the development and validation of a workplace attachment scale, namely the 'Echelle d'Attachement au Lieu de Travail' (ÉALT). Based upon the Theory of Place Attachment elaborated by Schumaker & Taylor (1983) and conceiving attachment to the workplace as an affective tie between a person and his/her work environment, this scale is derived from the Neighborhood Attachment Scale (Bonnes & al., 1997). More than 750 men and women working in different professional sectors participated in these studies. Preliminary results showed that the ÉALT has adequate levels of internal consistency and temporal stability. The construct validity of this unidimensional scale is moreover confirmed.
