FAZLA NİTELİKLİLİK VE SES DAVRANIŞI İLİŞKİSİNDE BİREYSEL VE DURUMSAL FAKTÖRLERİN ROLÜ: SİVİL HAVACILIK SEKTÖRÜNDE BİR ALAN ÇALIŞMASI

Abstract

Grounded in relative deprivation and social comparison theories, this study examined the relationship between perceived overqualification and both supportive and defensive voice behavior, as well as the mediating role of relative deprivation in these relationships. It further examined the moderating effects of servant leadership and group overqualification in the relationship between perceived overqualification and relative deprivation. The study's hypotheses were tested across two subsamples of employees from the civil aviation sector. In Study 1, data were collected from 204 employees and 32 supervisors across 32 work groups. In Study 2, data were collected from 121 employees; unlike Study 1, participants' supportive and defensive voice behaviors were evaluated through self-assessment. Across the two samples, it is demonstrated that perceived overqualification is positively and significantly related to relative deprivation. The other hypotheses tested in the study were rejected, including the mediating effect of relative deprivation in the relationship between perceived overqualification and supportive and defensive voice, and the moderating effects of servant leadership and group overqualification, tested separately and simultaneously. Study 2 further demonstrates that relative deprivation mediates the relationship between perceived overqualification and defensive voice behavior. These insights provide implications for managers and organizations on effectively managing overqualified employees.
