Penelitian kali ini bertujuan untuk melihat apakah adanya pengaruh antara variabel self-efficacy, kepribadian proaktif, dan work engagement berpengaruh positif terhadap employee voice behavior. Penelitian ini dilakukan terhadap 35 responden para dosen Fakultas Ilmu Seni UPH dengan pendekatan kuantitatif menggunakan metode PLS SEM, dimana data diolah dengan menggunakan program Smart PLS. Hasil yang diperoleh adalah variabel eksogenus self-efficacy dan kepribadian proaktif berpengaruh positif terhadap EVB (variabel endogenus), sedangkan work engagement sebagai variabel mediator menunjukkan arah terbalik terhadap variabel employee voice behavior. / In every organization, especially in the world of education, of course it cannot run alone and there is a need for collaboration between leaders, teachers and learners who are active in contributing to the organization.
