The current study aimed to identify the enablers of workers' ageing in workplace, by analyzing the direct path of I-deals and indirect path of Psychological Capital (PsyCap) among faculty members in the faculties of Zagazig University. To achieve this, five main hypotheses were developed. By using a survey method, primary data were collected through a stratified sample of 293 of those over the age of 45, including professors, associate professors, and fresh PH.D holders, in addition to full-time professors in ten of the faculties of Zagazig University. Using the path analysis method according to the AMOS program, the results revealed a significant positive relationship between the I-deals and both motivation to work, and workability among elderly faculty members. There is also a positive, significant relationship between I-deals and (PsyCap). Finally, the results demonstrated that (PsyCap) mediated the relationship between I-deals and both the motivation to work among older people and their workability. The study concluded by discussing the results, their theoretical and managerial implications, and presenting its limitations and future studies.
