A MULTIDISCIPLINARY APPROACH TO WORKFORCE DYNAMICS.THE A2A CASE STUDY

The research discusses from a multidisciplinary perspective the policies of human resource management adopted by the a2a Group, a former public company. In particular, using Kaplan-Meier survival estimates and Cox PH models, several analysis on the human resource planning will be discussed from different points of view. Firstly, the promotion system in place inside each formal organization now part of the a2a Group will be considered. Afterwards, patterns of career advancement affected by the nature of activities will be analyzed. Lastly the promotion system will be studied starting from the different pay grade systems in place inside the Group. All the analyses will also adopt an historical perspective, and in particular the sample will be divided in the years before and after the privatization process that interested the company. Finally, the impact of other relevant covariates such as the job category, the level of education, gender, and tenure will be considered.
