<![CDATA[Abstract. Rapid changes in the world of work require employees to actively convey ideas, suggestions, and concerns related to their work, known as employee voice behavior (EVB), comprising promotive voice and prohibitive voice. Proactive personality is expected to encourage this behavior among employees of information technology companies. This study examined the contribution of proactive personality to EVB among employees of information technology companies in Bandung City. This study used a non-experimental quantitative approach with a correlational (cross-sectional) design involving 116 employees, selected through convenience sampling. Data were analyzed using simple linear regression separately for each EVB dimension. Results showed that proactive personality contributed positively and significantly to promotive voice (R² = 0.495; t = 10.563; p < .001) and prohibitive voice (R² = 0.478; t = 10.226; p < .001), indicating that employees with higher proactive personality tend to be more active in proposing improvements as well as raising concerns about potential work-related problems. It is concluded that proactive personality is a consistent predictor of both voice dimensions. Abstrak. Dinamika dunia kerja menuntut karyawan untuk aktif menyampaikan ide, saran, maupun kekhawatiran terkait pekerjaan, dikenal sebagai employee voice behavior (EVB), mencakup promotive voice dan prohibitive voice. Proactive personality diperkirakan mendorong munculnya perilaku ini pada karyawan perusahaan teknologi informasi. Penelitian ini menguji kontribusi proactive personality terhadap EVB pada karyawan perusahaan teknologi informasi di Kota Bandung. Penelitian menggunakan pendekatan kuantitatif non-eksperimental dengan desain korelasional (cross-sectional) pada 116 karyawan, dipilih melalui convenience sampling. Data dianalisis dengan regresi linear sederhana secara terpisah pada tiap dimensi EVB. Hasil menunjukkan proactive personality berkontribusi positif dan signifikan terhadap promotive voice (R² = 0,495; t = 10,563; p < 0,001) dan prohibitive voice (R² = 0,478; t = 10,226; p < 0,001), mengindikasikan karyawan yang lebih proaktif cenderung lebih aktif menyampaikan usulan perbaikan maupun kekhawatiran atas potensi masalah kerja. Disimpulkan bahwa proactive personality merupakan prediktor yang konsisten bagi kedua dimensi voice.]]>
