This study investigated how perceptions of supervisor communication competence and source credibility were affected by the valence and synchronicity of a feedback message and the channel used to deliver the feedback message. Results indicated that those receiving feedback preferred phone calls rather than text messages as a channel for managers to deliver feedback. Also, supervisors delivering positive feedback were identified as more positive in general than those delivering negative feedback. Further results and implications are discussed.
