Fostering a Speak-Up Culture: Psychological Safety in Indonesia’s Startup Ecosystem

This study aims to examine the effect of psychological safety on employee voice behavior in startup environments. A total of 351 startup employees in Indonesia participated in this quantitative research using survey methods. Voice behavior was measured using the Employee Voice Behavior Scale, while psychological safety was assessed using the Psychological Safety Scale. Data were analyzed using binary logistic regression. The results showed that psychological safety significantly influenced voice behavior, χ²(349) = 6.940, p < 0.001, R² = 0.132. These findings indicate that employees who perceive a higher degree of psychological safety are more likely to engage in voice behavior, highlighting the importance of cultivating a psychologically safe climate in startup organizations.
