Discussion
This study sought to examine the relations between attachment security, job performance and job promotion, and the extent to which these relations might be mediated by particular social rank behaviors. In their exposition of attachment theory in adulthood, Mikulincer and Shaver (2007) propose that a pervasive sense of security make securely attached individuals more adept at dealing constructively with life’s challenges in all life spheres including the work domain. Our findings indicate that securely attached employees were indeed more likely than insecure employees to demonstrate better job performance fifteen months after their attachment style was assessed. In this context, our findings are consistent with attachment theory (Mikulincer & Shaver, 2007) and with previous research regarding the positive influence of secure attachment on job performance (e.g., Hazan & Shaver, 1990). Our findings further indicate that secure employees were approximately five times more likely to be promoted on their job in comparison to insecure employees, twenty nine months after their attachment style was assessed. As far as we know, this is the first study that examines the role of secure attachment in predicting future career advancement of full-time employees.
