A tour leader (TL) is a first-line service provider whose performance shapes a tourist's experience and satisfaction during a journey. We examine the moderating effects of the self-monitoring level of group package tour members on the relationship between the use of impression management (IM) tactics by TLs and tourists' subsequent job performance ratings (PRs) of a TL. Data from 485 responses of tourists from 59 outbound tour groups in Taiwan revealed that TLs' use of positive IM tactics -that is, ingratiation, selfpromotion, and exemplification -is positively related to tourists' PRs. In contrast, their use of non-positive IM tactics -that is, supplication and intimidation -is negatively related to tourists' PRs. Furthermore, tourists' self-monitoring appears to weaken the effects of supplication and intimidation on their PRs. We also found that tourists' level of self-monitoring is a stronger moderator when TLs use supplication than when they use other tactics.
