Despite the powerful mechanism of employee voice as a mediating variable in the relationships between ethical leadership and organizational identity, there is little evidence in previous studies regarding the mediation of employee voice in such a relationship. According to researchers, there is ample evidence of the correlation between leadership styles (authoritarian, ethical, and servant) and employee voice. Ullah et al. (
2020) and Bai et al. (
2019) have investigated the impact of ethical leadership on employee voice. But, these two studies failed to examine organizational identity (Bai et al.,
2019; Ullah et al.,
2020). On the other hand, irrespective of the mediating role of employee voice behavior, the relationship between organizational identity and ethical leadership has been assessed by Qian & Jian, (
2020). Therefore, organization identification is an individual’s perception of their position, including how they perceive themselves as part of the organization (Akhmadi et al.,
2023). Researchers have rarely examined the relationship between organizational identification and employee voice in a single model (e.g., Hu & Casey,
2021); instead, organizational identification has been documented as a mediator or moderator. For example, organizational identification has been shown to moderate employee voice (Knoll et al.,
2021). However, researchers also acknowledge that organizational identification plays an intermediate role in forming employee voices (Zhuang et al.,
2021). Organizational identification and voice are the result of social interaction between employees and the organization. Social exchange theory assumes that the exchange between employees and the organization is a reciprocal relationship, where good treatment by the organization will attempt to be reciprocated by employees with similar actions (Akhmadi et al.,
2023). In other words, when companies respect their employees, similar actions will be reciprocated concerning the company’s employees. If the company provides fair treatment and promotes an open climate for employee input, employees will not hesitate to contribute by voicing ideas, information, and important inputs to the organization (Charkhkar et al.,
2022). In line with social exchange theory, social identity theory is based on the premise that individuals identify as part of a group. In other words, individuals can use group identity to describe their own identity (Islam et al.,
2018). Social identity theory assumes that individuals evaluate various situations, including conflict, injustice, and discrimination, resulting in a tendency to evaluate negatively in their group. However, the respect and prestige they receive encourage stronger self-identification within the group (Fuller et al.,
2006). Existing studies have used social exchange theory and social identity theory as theoretical bases to explain organizational identification and employee voice behavior (Achmadi et al.,
2022; Wang & Yen,
2021).
Consequently, ethical leaders can demonstrate favorable behaviors and values to motivate employee participation and knowledge-sharing, leading to product, procedure, and service innovation. Since employee voice can provide adequate information to prepare the ground for organizational identity, it is imperative to evaluate its mediating role in the association between organizational identity and ethical leadership style.
Therefore, this study aims to assess whether ethical leadership style impacts on organizational identity, considering the mediating role of employee voice in digital startups in Iran. The research population includes the founders and managers of digital startups located in the science parks of the University of Iran including Yazd University in 2021.
This survey can add to the mainstream literature in the following manners: (1) it extends the employee voice literature and relates it to innovative, ethical leadership in its own right. It also highlights that the managers may use ethical leadership in digital startups, and (2) examining the mediating effect of employee voice contributes to the components of ethical leadership and organizational identity.
Theoretical background and hypotheses
Human behavior is acquired through direct experiences (such as the results of punishments or rewards) and indirect experiences by observing others’ behaviors and outcomes(Bandura,
1965). Accordingly, Bandura (
1965) put forward the social learning theory to emphasize the important role of observational learning in motivating individual behaviors. Brown et al. (
2005) described ethical leadership as a process of social learning through which employees can acquire direct and indirect experience in terms of ethics, moral values and codes by observing ethical leaders’ role modeling and management practices such as encouraging communication, contingent reward, and fair decision-making. Drawing from social learning theory, the literature argued that ethical leaders are legitimate models of employee normative behavior (e.g., voice). Through copying ethical leaders’ examples of speaking out against inappropriate actions (Walumbwa & Schaubroeck,
2009) or gaining positive vicarious experiences from those who ethical leaders reward for engaging in voice (Qi & Ming-Xia,
2014), employees learn that voice is expected and rewarded in their organizations, thereby reinforcing their knowledge of the necessity and importance of speaking out.
On the contrary, if a leader fails to set ethical standards through visible actions or implement a reward system, they would be perceived as “ethically neutral” (Trevino et al.,
2000). As a result, employees may be complacent, focusing on their short-term interests and be silent concerning others’ inappropriate behaviors (Lee et al.,
2017). Later on, social exchange theory was used as a supplement to social learning theory by a growing number of scholars to explain the effect of ethical leadership on employee communicative behaviors, indicating a focus shift from “leader influence” to “employee feedback” (Qi & Ming-Xia,
2014). Social exchange theory Blau (
1964) asserts that the principle of reciprocity generally drives people; that is, when they gain positive feelings during their interpersonal interactions with others, they are likely to reciprocate to others for the favorable treatment they received (Blau,
1964). Accordingly, in an organizational context, employees are willing to engage in good job performance or extra-role behaviors when satisfied with the work environment or the treatments the organization or manager provided (Ng & Feldman,
2012).
Based on the perspective of social exchange theory, the literature argued that the relationship between an ethical leader and their followers is termed “social exchange” rather than “economic exchange.” Such a relationship is based on shared identity, emotional connections, trust, caring and respect between the parties, reinforcing employees’ identification, affective trust, and loyalty to their leaders and organizations (Qi & Ming-Xia,
2014; Rasheed et al.,
2017). Employees involved in social exchange relationships would be motivated to reciprocate their leaders’ actions regarding extra effort and extra-role behaviors, such as voice (Li,
2022).
Through ethical leadership, leaders could develop a code of conduct to guide organizational behaviors, leading to positive outcomes, including good job performance, proactive behaviors such as helping and voice, and organizational commitment. Among those outcomes, employee voice (i.e., employees offer promotive or problem-focused suggestions) and employee silence (i.e., employees intentionally withhold information and ideas that might be useful to their organizations) have received a large amount of attention as employees’ use of voice involves complicated motivations and determines the success of the organization of all kinds (Morrison,
2014).
The current literature suggests that ethical leaders can encourage employees’ use of voice and reduce employee silence as such leaders occupy themselves in leading activities, such as caring about the best interests of followers and optimizing work settings and environment to promote followers’ potentials (Hassan et al.,
2014). The idea has been empirically supported by a handful of cross-sectional studies that reported ethical leadership positively predicted employee voice (Qi & Ming-Xia,
2014; Walumbwa & Schaubroeck,
2009) while negatively predicting employee silence. However, there is also the possibility of reverse causation in the target variables—that is, leaders may benefit from followers’ voice to continually advance their leadership behaviors to meet followers’ expectations of ethical leadership (Li,
2022).
Leaders are the key component in the managerial chain of organizational identification since the more a leader effectively mobilizes and influences followers, the more they will be seen as group prototypical and as someone who can embody what is defining about the group identity (Hogg et al.,
2012). Ethical leaders are the people who are more prototypical in an organization in which business ethics and sustainable development are high on the agenda. For example, ethics is the key competence in the public sector that should be highlighted when selecting the right person to succeed in a leadership position.
Ethical leaders guide the organization toward sustainable development and have advantages in shaping internal brand and external prestige (Van Knippenberg,
2011). Such contributions of ethical leadership play a critical role in cultivating employees’ organization identification. Ethical leaders manage followers in a caring and humane-based way. They are caring listeners, encouraging the free airing of views, paying more attention to their followers’ potential and values, and encouraging innovation and development (Brown et al.,
2005; Li,
2022).
Consequently, the followers are likely to generalize supervisory treatment to organizational treatment and sublimate their satisfaction and positive emotions into the identification and commitment toward their organization. Organizational identification leads one to experience organizational identity as both self-describing and self-guiding (Hogg et al.,
2012). If employees define themselves by the same moral attributes or positive virtues that define their organization, they are more likely to engage in voice on behalf of organizational agents and vice versa. Secondly, organizational identification motivates a person to see him- or herself through the lens of organizational membership and enables the person to take the organization’s best interest to heart and incorporate the organizational interest into their self-worth (Van Knippenberg,
2011). Therefore, the salient “collective self” would be the driving motive forcing employees to play a good role in defending misbehaviors and have a go at providing positive suggestions for the sake of the organization.
Moreover, it is believed that the ethical leaders’ development of employee voice can lead to organization identity. Consequently, perception of organizational identity associated with employees’ individual and organizational values can lead to unity within the organization. It will likely be established through verbal communication (Kopaneva,
2021). Particularly, Peng & Wei (
2020) believed that employee voice could be encouraged through the significant effects of ethical values in organizations. Consequently, behavioral integrity, open workplace environment, and organizational ethical values can effectively result in employee voice (Peng & Wei,
2020). Bednar et al. (
2020) asserted that HRM pursues communicative processes involving the distribution of organizational values, goals, and perspectives. It will help employees manage the constant changes and challenges at work (Bednar et al.,
2020). Therefore, organizational identity can moderate occupational outputs, team dynamics, motivational elements, and employees’ behaviors and viewpoints (Zagenczyk et al.,
2021). So, ethical leaders aim to prepare and inspire employees to seek organizational identity because they will be more likely to endeavor to achieve organizational goals in the long-run.
Employees observe their leader’s behavior through role modeling and learn task requirements, appropriate behavior, and expected performance (Ogunfowora et al.,
2021). Accordingly, employees are encouraged to speak to their leader when they notice inappropriate behavior that contradicts what they have learned. For instance, previous studies have revealed that employees’ willingness to report problems is important to ethical leaders (Thi-Minh-Ngoc Luu & Pham,
2020). Moreover, Watson et al. (
2014) proposed that the following five issues can encourage sustainable employee involvement: (1) leaders can build mutual trust in the organization and emphasize organizational values; (2) leaders’ trustworthiness can lead to a more positive organizational image in society; (3) leaders are required to plan for future perspectives, and help employees make efforts to achieve organizational objectives by empowering them to deal with possible changes; (4) leaders should help employees maintain a balance between their job and their personal life by providing flexible occupational duties and highlighting employees’ health and well-being; and (5) leaders should develop positive communication with employees through mutual respect to help manage the barriers and obtain organizational success (Thiensiri,
2021; Watson et al.,
2014).
Similarly, Liu et al. (
2022) claimed that honesty, respect, and selflessness can positively impact employees’ commitment and engagement, leading to organizational objectives (Liu et al.,
2022). According to ethical leadership premises, leaders’ behavioral trustfulness is critical as the organizational plans and ultimate outcomes (Bai et al.,
2019). Eventually, employees may consider their manager a role model because of the leader’s ethical characteristics such as trust and honesty (Ejaz et al.,
2022).
Voice behavior is shown when ethical leaders inspire employees to express their suggestions and thoughts for development and courageously report inappropriate or immoral behavior (Kwak & Shim,
2017). According to Ullah et al. (
2021), ethical leadership should ask employees to share ideas and constructive comments that help manage and resolve occupational challenges through innovative behaviors, open interactions, mutual trust, and a sense of fairness (Ullah et al.,
2021). In addition, since ethical leaders create a climate of trust and fairness, employees feel they can speak to their co-workers about anything because they share the same principles taught by the same person (Cheng et al.,
2022). Employees learn how to behave correctly by observing ethical leader behavior. When ethical leaders build an authentic and unbiased environment, they encourage subordinates to voice their suggestions and speak out about their thoughts without concern, thereby resolving possible complications and developing new working techniques (Natividade et al.,
2021). Ali Chughtai (
2016) claimed that innovative ideas and fresh opinion in the organization might indicate that employees are free to share their constructive comments, mainly when there are disagreements between employees and leaders (Ali Chughtai,
2016). Brown & Treviño (
2006) asserted that dependability and fairness are among employees’ valued leadership characteristics. Such virtues can determine the ethical leader’s acceptance in the organization as a trusted role model, which leads to greater employee engagement (Brown & Treviño,
2006). Ethical leadership endorses organizational identity because it can develop ethics and trustworthiness among employees and enhance organizational ethical norms (Arshad et al.,
2021).
At the conceptual level, leaders who are seen as more trusting should promote and raise identification with the work group or organization (Tyler & Smith,
2014). Specifically, because ethical leaders are proactive, which, in turn, increases cooperation accordingly, we expect such leaders should promote organizational identification. Scholars’ research (Al Halbusi et al.,
2020; Tyler & Blader,
2013) suggests that people identify more with social institutions when trust is present and individuals’ need for psychological safety is met. Empirical research provides evidence for this notion. For example, several studies have shown that characteristics of ethical leaders, such as openness and trustworthiness, are positively related to organizational identification (Qi & Ming-Xia,
2014). It will then prepare the grounds for the attainment of organizational objectives.
Studies have been conducted on the relationship between employee voice and ethical leadership, showing that ethical leadership positively influences employee voice (Bai et al.,
2019; Zhu et al.,
2019). Furthermore, ethical leaders motivate employees to speak about ethical issues. Research by Weiss et al. (
2018) has also indicated that leaders’ features and the use of inclusive language such as “we,” “our,” and “us” have a positive influence on voice behavior (Weiss et al.,
2018). However, Bhatti et al. (
2021) claimed that the effect of ethical leadership on voice behavior is not equal across each employee since employees’ own moral values are not the same (Bhatti et al.,
2021). For instance, employees who believe that people’s character is fixed, such as strong moral beliefs, may not be willing to speak up because they think change is impossible, and voicing is thus pointless.
After reviewing prior studies, Kalshoven et al. (
2011) developed a seven-dimensional model of ethical leadership behavior: integrity, fairness, role clarification, orientation, ethical guidance, collaboration, and sharing power. The first three dimensions (fairness, power-sharing, and role clarification) are also supported by earlier scholars. The fairness dimension demonstrates how leaders maintain integrity in treating their colleagues (Kalshoven et al.,
2011). Their choices are fair and free from favoritism, which is why their behaviors are trustworthy. Power-sharing dimension of ethical leadership demands a decentralized decision-making process. The leader listens and accommodates various ideas of the followers (Gollagari et al.,
2021). Under power-sharing, they consider the followers equal partners and allow them to play a larger role in decision-making. Moreover, the ethical leader’s fair attitude towards the group, the ability of the leader to share power with the followers, and clarifying their role expectations make the leader a credible and legitimate figure for the followers, which enhances followers’ trust in the leader (Sharma & Pardasani,
2021). Researchers called it an empowering dimension of ethical leadership. Maintaining transparency in communication is the root of ethical leadership’s third dimension (role clarification). The ethical leader must clarify the subordinates’ performance expectations and related responsibilities.
