2.1 Intellectual Humility Leadership and Positive Work Attitude
One of the ways in which organisations can achieve higher performance is by influencing employees' attitudes towards their work and through the configuration of practices that support intrinsic motivation (Arifin 2020). Judge & Mueller (2012) define work attitude as "an evaluation of the job, expressing one's feelings, beliefs, and attachment towards the work." Bagozzi states that the term attitude often encompasses preferences, feelings, emotions, beliefs, expectations, judgments, appraisals, values, principles, opinions, and intentions. Employee work attitudes can be divided into positive and negative work attitudes, with attitudes likely preceding and predicting behavior (Ajzen & Fishbein 1980), indicating that attitudes are important focal and measurement points for behavior antecedents. Employee work attitudes are influenced by internal factors, including work-related values, self-efficacy, threat assessment, organizational commitment, skill development, employee trust, and career advancement (Aâ 2013; McNatt & Judge 2008; Mathew & Zacharias 2016; Rebeka & Indradevi 2015). External factors include relationships with colleagues, leadership style, and organizational policies or treatments (e.g., work environment and conditions, organizational justice, and compensation) (Ahmad et al. 2020; Khuwaja et al. 2020; Noah 2012; Ramamoorthy & Flood 2002). For decades, leadership practices/styles have been a focus for organizational researchers. The Stimulus-Organism-Response (SOR) theoretical framework posits that stimuli may come from external contexts, organisms form psychological states in response to stimuli, and after a series of psychological activities, organisms take behavioral actions in response (Warkentin 2019). Leaders' behaviors and styles can be viewed as stimuli sources, which employees receive, undergo psychological activities, and finally react—potentially facing work more positively/negatively.
Many articles discuss the impact of different leadership styles on employee work attitudes, but none consider the perspective of intellectual humility leadership. Intellectual humility qualities, such as avoiding intellectual overconfidence and respecting others' views, may be key components in reflecting another person's subjective state in cognitive processes. This may lead to understanding others' perspectives, potentially resulting in greater employee emotional satisfaction, happiness, and positive work attitudes. Therefore, intellectual humility leaders help employees shape positive work attitudes by fostering a respectful and cooperative environment. Organizational researchers emphasize that leadership approaches and practices significantly influence employee attitudes and organizational performance (Allen et al. 2003). Intellectual humility leaders exhibit moral authority and respect towards others, often being more receptive to employees' suggestions and opinions, creating a collaborative and trusting environment (Frostenson 2016). This encourages employees to form positive work attitudes, promoting a virtuous cycle of enhanced performance and satisfaction.
H1: There is a positive relationship between leaders with intellectual humility and employees' positive work attitudes.
2.2Intellectual Humility of Leaders and the Thriving at Work and Work Performance of New Generation Employees
Intellectual humility is a leadership quality that encompasses both humility and intellectual acumen. In the field of psychology, it reflects a leader's recognition of their own limitations. Interpersonally, intellectual humility is associated with numerous positive and prosocial qualities, such as agreeableness, openness, perspective-taking, helpfulness, generosity, and the quality of social relationships (Poter et al., 2021). Regarding the positive relationship between leaders' intellectual humility and employees' thriving at work, research indicates that intellectual humility leaders can create a positive and uplifting work environment by understanding and respecting their employees, especially when disagreements arise. Individuals with high intellectual humility are more tolerant of differing viewpoints and are less likely to disparage those with whom they disagree (Leary, 2017). More generally, IH correlates with an agreeable, open, and supportive interpersonal style, which leads people who are more intellectual humility to be liked better than those low in IH (Porter & Schumann,2018). In addition, their open, less contentious style leads group leaders who are higher in IH to elicit fuller participation by group members, promoting greater creativity and higher group satisfaction. Leaders with the trait of intellectual humility typically demonstrate sensitivity to the needs of their employees and pay attention to individual differences among them, intellectual humility can promote more diverse groups and organizations where a true sense of belonging results in more voices being heard. Ultimately, this will create safer settings for those with marginalized identities, thereby establishing a relationship of trust and resonance, which plays a positive role in enhancing employees' thriving at work (Krumrei-Mancuso, 2022).
Secondly, research has found that leaders who express humility have been shown to increase team performance. The reason for this is that leaders who recognize the limits of their knowledge and are open to learning are well-positioned to attend to their followers and become better leaders (Rego et al., 2017). They provide a safe work environment that encourages employees to think and act more creatively at work, which in turn improves overall work performance. An intellectual humility leadership style may help reduce conflict and stress in the work environment. A relatively relaxed and cooperative-oriented work environment may help improve employee work performance (Mukhtar et al., 2023). Intellectual humility leadership can lead to higher work engagement and commitment from employees. These positive employee attitudes are typically associated with higher work performance (Meskelis & Whittington).
Based on the above viewpoints, this paper proposes hypotheses H2 and H3:
H2: There is a positive relationship between leaders' intellectual humility and the thriving at work of the new generation employees
H3: There is a positive relationship between leaders' intellectual humility and employees' work performance.
2.3 Positive Work Attitude and Thriving at Work and Work Performance
Research indicates that thriving at work can serve as "happy productivity," bringing transformative benefits to both organizations and individuals. It can increase organizational productivity by an average of 31%, sales performance by an average of 37%, and customer satisfaction by an average of 12%. From the perspectives of employee stability and organizational competitiveness, ensuring employees thrive at work is a crucial task for managers. Despite the importance of enhancing the thriving of new generation employees, many companies still regard it as an insignificant issue. Spreitzer et al. (2005) first introduced the concept of thriving at work, defining it as a psychological state where individuals simultaneously experience vitality and learning. Every employee potentially possesses latent thriving potential, which can be activated and mobilized by leadership and other situational factors. Carmeli & Spreitzer (2009) also contend that thriving is essentially a positive subjective experience that enables individuals to perceive growth and progress at work.
Spreitzer et al. (2005) also developed a theoretical model of thriving at work, explaining how certain individual characteristics (e.g., knowledge and positive affect), interpersonal/relational characteristics (e.g., support and trust), contextual features (e.g., job autonomy and a climate of trust), and agentic work behaviors (e.g., task focus and exploration) lead to thriving at work. Klein et al. (2019) demonstrated that thriving at work positively influences positive work attitudes. However, from both theoretical and empirical research perspectives, positive work attitudes can also significantly affect thriving at work.
Positive work attitude refers to the positive evaluation of the object of thought (Williams, 2016). Studies have shown that work performance and compensation performance are related to the formation of positive work attitudes (Gagné & Deci, 2005; Ogbonnaya et al., 2017). However, contingent compensation may exacerbate work pressure, potentially diminishing its positive impact on employee attitudes. Unfortunately, these studies have not explored positive attitudes as a stimulus source for examining their impacts. According to social exchange theory, employees' positive work attitudes and behaviors are influenced by organizational rewards and support. This positive exchange relationship can stimulate employees' work engagement and enthusiasm, thereby enhancing their thriving at work. Positive work attitudes such as high job satisfaction, strong organizational commitment, and occupational confidence can improve employees' psychological states and work motivation, prompting them to exhibit greater focus and dedication in their work (Halepota, 2011; Herman, 2013). Furthermore, employees with positive work attitudes are more likely to seek learning and growth opportunities in their work, enhancing their career development potential and work experience (Weer & Greenhaus, 2020). Therefore, there is a bidirectional interactive relationship between positive work attitudes and thriving at work. Enhancing employees' positive work attitudes is an effective way to boost their thriving at work.
Such positive work attitudes are not merely emotional experiences; they significantly influence individual behaviors. Research indicates that employee attitudes have a guiding and driving function for work efficiency (Susanty & Miradipta, 2013). In this context, work performance, as a key indicator, becomes a primary focus for organizations. Work performance refers to the efficiency and effectiveness with which employees complete tasks in their roles. It is a crucial metric for evaluating how well employees fulfill their job responsibilities over a specific period (Caillier, 2010). Positive work attitudes, including high work engagement, positive emotional experiences, and organizational commitment and identification, encourage employees to fully dedicate themselves to their tasks, thereby improving work efficiency and quality (Somers et al., 2000; Van et al., 2006).
In summary, positive work attitudes make employees more likely to experience satisfaction, achievement, and positive emotions, thereby enhancing their thriving at work. Simultaneously, these positive attitudes drive employees to be more focused and dedicated to their work, improving work performance and creating greater value for the organization. Therefore, we propose the following two research hypotheses:
H4: There is a positive relationship between employees' positive work attitudes and their thriving at work.
H5: There is a positive relationship between employees' positive work attitudes and their work performance.
2.4 The Moderating Role of Employees' Core Self-Evaluation
For a long time, scholars have been interested in understanding the factors that influence employees' positive work attitudes. These factors include not only external elements such as the work environment but also intrinsic factors like personality traits. Consequently, Judge, Locke, and Durham (1997) proposed the concept of core self-evaluation (CSE). CSE is manifested through four personality traits: self-esteem, generalized self-efficacy, locus of control, and neuroticism. These four specific personality dimensions are unique yet belong to a higher-order factor known as CSE (Kim, 2015). Compared to employees with low CSE, those with high CSE are likely to evaluate their organizational environment more positively. They view themselves as valuable, confident, and proactive, and experience positive events at work, ultimately gaining benefits from the context. This, in turn, can increase their subsequent engagement within the organization, as their positive outlook and experiences make them appreciate any support provided by the organization (Henson & Beehr, 2018).
Most studies on leadership and performance regard subordinate performance as the result of the interaction between leaders and employees, focusing on the causal role in this process. Given that effective leaders can enable followers to realize their optimal capabilities (Bass & Bass, 2008), leaders can amplify the positive relationship between followers' CSE and their outcomes. High-CSE individuals also expect to establish high-quality relationships with their superiors within the organization. Some scholars have examined the relationship between transformational leadership, servant leadership, authentic leadership, and CSE. Although these studies investigated different dependent, mediating, and moderating variables, they all confirmed the positive correlation between these leadership styles and CSE, with servant leadership and CSE being mutually influential (Resick et al., 2009; Schmidt, 2008; Rodríguez-Carvajal et al., 2010).
However, they overlooked how leaders with intellectual humility affect the relationship between CSE and employees. Intellectual humility leaders help establish positive leader-employee relationships, providing a conducive work environment that influences employees' core self-evaluation and work attitudes. Individuals with high core self-evaluation typically possess high self-esteem and a strong sense of identity. In an environment of intellectual humility leadership, these employees are more likely to feel respected and understood (Leary, 2022), thereby enhancing their job satisfaction and positive work attitudes. Additionally, employees with high core self-evaluation are likely better at regulating their emotions, including maintaining optimism and flexibility when facing challenges. This positive emotional regulation helps manage work-related stress (Neves & Champion, 2015), contributing to the creation of a positive work environment alongside intellectual humility leadership. Therefore, this paper proposes hypothesis H6: intellectual humility leadership positively influences employees' positive work attitudes, with employees' core self-evaluation positively moderating the relationship between intellectual humility leadership and positive work attitudes.
H6: Employees' core self-evaluation positively moderates the relationship between intellectual humility leadership and positive work attitudes.
2.5 The Mediating Role of Positive Work Attitudes
Within organizations, establishing high levels of employee thriving at work and high job performance often lacks top-down prioritization. For instance, impulsive leaders may harm and undermine their followers and organizations, failing to create a psychologically safe work environment, leading to increased work stress for employees. Employees often express frustration, stating, "You either guide me, or you are just adding to my troubles" (Myatt, 2013). In contrast, leadership styles like transformational leadership broaden employees' interests and develop followers' abilities (Baas et al., 2008). Leaders who demonstrate "thriving" behaviors are shown to be 17% more effective than their less thriving counterparts. Unfortunately, these studies have not explored the mediating mechanisms through which different types of leadership influence employee thriving. Based on the SOR (Stimulus-Organism-Response) theory, intellectual humility leadership can be viewed as a stimulus within the organization. It influences employees' internal states, such as cognition, emotions, and attitudes, which in turn trigger different responses from employees.
Specifically, employees' positive work attitudes can be seen as an organic response to this leadership style, reflecting their recognition of and positive emotional experience with the leadership approach. This positive work attitude is considered an organic reaction formed under the stimulus of intellectual humility leadership. Furthermore, employee well-being and job performance are seen as two significant responses. Intellectual humility leadership indirectly influences employee thriving and job performance by affecting their positive work attitudes. Therefore, this paper proposes hypothesis H7.
H7: Positive work attitudes mediate the relationship between intellectual humility leadership and employee thriving and job performance.
