Note(s): n = 311. *p < 0.05; **p < 0.01; ***p < 0.001. ΔR² and ΔF are used to show change in R² and F, respectively, when the interaction term was included. A-path refers to the path: servant leadership → burnout, b-path refers to the path: burnout → knowledge-hiding behavior, and c’-path refers to the path: servant leadership → knowledge-hiding behavior
