5. Discussion and conclusion
5.1. Discussion One observation made by the current study, which has never been reported in previous research, is that flight attendants with different seniorities and positions have significantly different motivations to conduct voice behavior. First of all, senior crew members and chief pursers tend to speak up with the aim of improving the overall safety performance and benefiting the entire organization. Being experienced professionals or leaders, they realize better than other crew members that safety is regarded the core value in the airline industry (Atak and Kingma, 2011), and how important overall organizational performance is.
