They understand customer’s needs and the changes of the market quite well. So if employees are willing to express their own ideas and propose essential suggestions timely to the organization or team for improvements, it will be valuable and useful to promote organizational innovation. It’s indeed a key factor to maintain organization’s competitive advantages.
Therefore, this study investigates locus of control, leader-member exchange, voice safety, voice efficacy, overall effectiveness of the relational model, what kind of personality traits of employees are easier to demonstrate their voice efficacy and under what circumstances will lead the staff to show their voice behavior.
This research adopted questionnaire survey and collected 347 valid ones. The returned questionnaires were analyzed by descriptive statistical analysis, reliability analysis, correlation analysis and regression analysis.
Main findings are as follow:
1.Staff who has internal locus of control will have a significant impact on voice efficacy. This means that when employees perceived their higher internal locus of control, the impact of their self-efficacy will increase as well in suggestions.
2.The leader-member exchange can significantly affect the quality of staff awareness of voice safety in organization, but also enhance their voice efficacy.
3.If an employee perceives the situation securer in his/her organization, and they are more likely to exhibit his/her voice behavior. Empirical results show that the voice safety enhances the voice efficacy.
4.The mediating effects psychological empowerment on leader-member exchange, also voice safety and voice efficacy are verified.
5.Voice safety will not strengthen the effectiveness of internal control with personality tendency of staff presumably because those who have internal locus of control personality are more proactive, relatively unaffected by the behavior of situational factors.
The recommendations of this study were based on the literature review and empirical findings and can be a reference for managers and organizations for the future use.
