Employee voice is perceived as an approach with both significant advantages and disadvantages. The current study aims to analyse the behaviours of supervisors when endorsing the ideas of employees who raise promotive voices and consider the employees positively for the development of quality relationships. Specifically, 970 employees were recruited from various small and medium enterprises (SMEs), including manufacturing and electronics companies, in Pakistan for the current study participation. Data collection was conducted in two stages through two sources (supervisors and subordinates) before examining the collected data on the Mplus software for random coefficient regression analyses. Subordinates’ promotive voice was significantly and positively correlated to the Leader-Member-Exchange (LMX) quality and creative idea endorsement when supervisors interpreted the voice as driven more by performance enhancement motives instead of impression management motives. The findings suggested that performance enhancement motives and impression management motives would produce contrasting material consequences for subordinates. The present study limitations and future research directions were also discussed.
