While legal protections against sexual harassment are crucial, their implementation could have unintended consequences. This study explores the potential downside of these protections-fear of false accusations-and its impact on cross-gender mentoring in Taiwanese workplaces. Drawing on social exchange theory, we investigate how fear of accusations might discourage valuable mentoring relationships between men and women. Through an intercept survey, we examined whether these concerns may lead to reduced mentoring opportunities for women, potentially hindering their career advancement. We proposed new constructs and analyzed the model using SmartPLS 4.1. Our findings reveal a complex dynamic: fear of accusations does appear to decrease cross-gender mentoring, raising concerns about its impact on women's career trajectories. However, the findings also suggest that men support sexual harassment laws, still believing these laws are needed. We discuss our model and its implications; additionally, we emphasize the need for strategies that balance legal protections while also fostering positive mentoring relationships.
