Specifically, mentoring encourages prot\u00e9g\u00e9s to share knowledge with other prot\u00e9g\u00e9s within the mentee-prot\u00e9g\u00e9 group (in-group favoritism) but hide knowledge to employees in other mentor-prot\u00e9g\u00e9 groups (out-group derogation). The opposing results are mediated by prot\u00e9g\u00e9 cohesion and group territoriality, respectively.
