Communication Power as a Mediator on Networking and Career Success: A Structural Equation Modeling Approach

Information is power. Developing a network of contacts inside and outside of organization provides immense and valuable information which can be beneficial in many ways. Indeed, internal and external contacts can provide opportunities to advance in one’s career. Networking behaviors build and maintain informal contacts to enhance career success (Forret & Dougherty, 2004; Luthans, Rosenkrantz & Hennessey, 1985; Michael & Yukl, 1993). Networking is positively related to both objective and subjective measures of Abstract

However, people rarely make use of their existing networks effectively.They think that if they can perform well, they can be acknowledged and get promoted.With modern technology, they cannot stay in isolation.Hopefully, the internally connected employees are also popular to the outside organizations.That is why boundary spanners are useful for organization linkages.Therefore, they have to harness the contemporary technology to project themselves because acknowledgement comes across borders, not just organization, but worldwide.If they want support from peers, they can get acknowledged for the expertise through making use of their linkages.
The present study will extend the existing knowledge in this field.Although, we know networking affects career success; not much is known about how it happens.With the empirical evidence on how network affects career success, both individual and organization will get the benefits.Individuals, who progress well in their career, tend to be loyal and organization is able to retain them (Aquino, Griffeth, Allen, & Hom, 1997).
This study contributes to the communication literature.For example, this study integrates the issues of networking behaviors, communication power, career success and personality.Therefore, this study is unique in such a way that networking behaviors involve both the internal and external entities to the organization.They are studied in relation to information power and relationship power.Such knowledge can help employees and managers to better target their networking behaviors internally and externally.Relatively little, or in some cases no, prior research exists on these outcomes.The present study tests a comprehensive model of employees' career success involving several predictors, which are based on past research.It is expected that such model is able to provide evidence regarding the network contribution to career success among employees.

Previous
research on the connection/relationship and information power and career success is rare.We did not find any prominent research in this topic except studies by Bahniuk and her colleagues.Bahniuk, Hill and Darus (1996), and Dobos, Bahniuk and Hill (1991) conducted a few series of studies on this topic.Hill, Bahniuk and Dobos (1994) developed a power-gaining communication model based on information power and connection power.They found that powergaining communication relationship enhances career success.

Networking
The present study adopts previously welldefined networking which states that "behaviors that are aimed at building, maintaining, and using informal relationships that possess the potential benefit to facilitate work-related activities of individuals by voluntarily granting access to resources and maximizing common advantages" (Forret & Dougherty, 2004;Wolff & Moser, 2008).Networking is analyzed at the behavioral level (Michael & Yukl, 1993;Wanber, Kanfer & Banas, 2000;Witt, 2004).Networking success depends on the ability to interact and to relate with others and that success comes not only with whom one knows, but also how one knows one another.

Career Success
Career success is conceptualized as "both real/objective and perceived/subjective achievements in individuals' work lives" (Judge, Cable, Boudreau, & Bretz, 1995).For the present study, only objective career outcomes will be used.From the standpoint of objective career outcomes, career success of employees is mainly measured based on money and position (Feldman, 1989;Hall, 1976).Career success can also be looked at in terms of promotion, salary increment, individual performance, and one's success and contributions to the organization (Bowen, 1986;Kanter, 1977;Kram, 1983;Levinson et al., 1978;Morris, 1969;Phillip-Jones, 1982;Speizer, 1981).Furthermore, objective career success is observable career accomplishments and they are tangible outcomes in nature.Therefore, objective career outcomes can be seen as increase in annual salary, scope of responsibility, promotion to a higher level, and receiving bonuses, incentives, and other fringe benefits.

Information Power as a Mediator
In this study, we propose communication power comprised of information power and relationship power.Information power comes from access to and control over information.
According to Hershey, Blanchard and Natemeyer (1979), "information power is based on the possession of or access to information that is valuable to others (p.419).Therefore, the person who possesses the needed information by other is influential and becomes powerful.Increased access to information enables employees to increase their knowledge and to help them deal with specific issues that they might have at work.Control of information flow usually relates to formal communication network.The more valuable the resource is to the company or superior and the greater is the level of mastery the person has on the information or materials, the more influential he/she will become.
Relationship power is based upon whom you know.Relationship power or connection power as termed by Hershey, Blanchard and Natemeyer (1979) refers to the power one gains from relationship with the power of others.Therefore, when one has the connections, he/she is bound to have the relationship power and thus becomes a popular emergent leader.The influence of power within the interaction of employees at workplace is significant.If one can reach, either directly or indirectly, the dominant coalition in the organization, one has a better prospect for influence and control over the whole organization.
Being liked and highly regarded among other teams and departments will increase one's chance of being promoted or influencing the outcome of a decision.Work connections are vehicle for resource and reward exchange.The result is that better-connected people do better (Burt, 2000).

Personality and Self-Efficacy As Moderators
A proactive personality is identified as "someone who is relatively unaffected by situational forces, and who actively initiates environmental change" ( Self-efficacy can moderate behavioral change (Bandura, 1977).Since self-efficacy refers to the belief in one's capability to perform a specific task, therefore, it can be summarized as one's capabilities to organize and execute courses of action required to attain desired goal, specifically, own performance at workplace (Bandura, 1986).Therefore, a self-efficacious employee is anxious to learn from others for self-development.With the support from networking and communication power, individuals with high self-efficacy are able to perform better and thus, succeed in their career endeavor.
Based on the above literature (Figure 1), we develop the following hypotheses: H1: Networking positively correlates with career success.H2: Networking positively correlates with communication power.H3: Communication power positively correlates with career success.H4: Communication power mediates the relationship between networking and career success.H5: Proactive personality moderates the relationship between communication power and career success.H6: Self-efficacy moderates the relationship between communication power and career success.

Methodology
The study employs a quantitative research design.It uses a survey method and used questionnaire as the research instrument for data collection.A total of 308 respondents, comprising of the middle-level management level, representing various companies, such as, manufacturing, services, health, and education, were collected for the duration of two months.Trained enumerators were assigned to various locations in Kuala Lumpur and Selangor, Malaysia.The constructs are found to be reliable with Cronbach's alpha (Table 1) for networking (α=.907), communication power (α=.929), personality (α=.896), and career success (α=.928).The dimensions of each construct were further confirmed by using Structural Equation Modelling (SEM) AMOS.

Findings of the Study
The majority of the respondents (n=308) of the study are Malays (81.8%), comprising of 162 females and 146 males, mainly belonged to the 26-35 age group (43.2%), and with Bachelor's degree (46.1%).In terms of jobrelated characteristics, the respondents mainly worked in the public sector inclusive of with the Government of Malaysia (51.9%) worked in the private sector (48.1%) and with 158 of them with 1-5 years of working experience, almost all work on a full-time basis, as executive officers (36.0%) and on a full-time basis.

Measurement Model
Using Maximum Likelihood (ML) Estimation, Confirmatory Factor Analysis (CFA) was conducted separately for all the constructs in this study: internal contact (INT), external contact (EX), information power (INF), relational power (REL), and career success (CS) to test their reliability and validity.4).The measurement model (Model 2) suggests adequate fit to the data (X 2/ df=1.752,CFI=.935,TLI=.928,RMSEA=.049).The factor loadings and covariance were statistically significant at .05.The highest correlation was between relational power and information power (r=.76, p=.000), followed by external networking and relational power (r=.57, p=.000).

Structural Model
Using the same criteria as discussed in the measurement model, the fit statistics were satisfactorily good, with X 2 /df=1.945,CFI=.917,TLI=.909,RMSEA=.055(Figure 3).This study hypothesized that the two dimensions of networking (internal and external) would have significant impact on the two dimensions of communication power (information and relationship), which in turn, significantly influence the career success among the respondents.

Mediating Effect of Communication Power Dimensions
The mediating test was conducted based on Baron and Kenny's (1986) guidelines and it was confirmed with the Sobel test (1982).
Baron and Kenny suggest that all variables concerned must be significantly related to one another.The mediator should significantly be affecting the outcome variable.Internal contact and external contact are exogenous variables in this study, whereas information power and relational power are the mediating variables.Career success is the only endogenous variable.
Looking at the path coefficients of the revised model, it was found that the impact of the exogenous variables (internal contact and external contact) on information power and relational power were statistically significant.However, they had no direct effects on the endogenous variable.In addition, information power and relational power (the mediators) had significant effects on the dependent variable.Therefore, the recommended criterion for mediation testing was achieved.
Sobel test the significance of mediating effects.The Sobel test suggested significant t-tests for external contact (t=1.876,p=.030) indicating that information power fully mediates the relationship of these constructs with career success, whereas relational power (t=1.585,p=.056) did not mediate internal contact on career success.However, information power significantly mediates on internal contact toward career success (t=2.662,p=.003), as well as on external contact toward career success (t=3.029,p=.001).

Moderating Effect of Personality
Structural invariance was conducted in order to see whether the model works in a similar way for both low (N=153) and high (N=155) proactive personality groups.Table 6 summarizes the results of invariance analysis (moderating effect).As for the proactive personality, the Chi-square for the unrestricted model was 1287.281(df=f 742), whereas the Chi-square for the fully constrained model was 1329 (df=769).The Chi-square difference (41.947) was significant since it is more than the critical value (CV=40.11).It means that both low and high personality groups are different at the structural level.Overall, it can be concluded that proactive personality moderates the revised hypothesized model.General self-efficacy was also tested for its moderating effects on the hypothesized model (Figure 3).The Chi-square value of the unrestricted model (1220.04,df=736) was This study tests the mediating effect of communication power dimension on networking dimensions toward career success.This study validated a model hypothesizing that internal contact and external contact are influential factors of information power and relational power, which in turn, influence the career success.
Prior testing the hypothesized model, a confirmatory factor analysis using MLE, to provide evidence of the construct validity and reliability, was conducted.The structural model, then, was tested using the same criteria and adequately fitted to the empirical data.There were significant impact of internal and external contact on both information power and relational power.The information power significantly mediated the relationship of the two dimensions of networking with career success, whereas relational power did not mediate that relationship.On the other hand, personality dimensions, namely, proactive personality and general self-efficacy significantly moderated the hypothesized model.Therefore, all the hypotheses are supported.

Discussion and Conclusion
This study examines how networking contributes to career success.Specifically, it tests communication networks, organizational contacts, and communication power on career success.The study found that both social and professional networks enhance career success.
The theory of social capital that postulates active interaction among people in a circle or group is used to gain access to information which is perceived as valuable is supported by the study.The significant relationship between networking and information power supports the previous findings (Forret & Dougherty, 2004;Wolff & Moser, 2006) that suggest organizational behavior that is aimed to build, maintain and use informal relationship is to gain benefits and common advantages.The benefits gained from the networking could enhance an individual's reputation in acquiring valuable rewards and resources from the organization regardless of the actual job performance (Ferris & Judge, 1991;Luthans et al., 1988).
The study implies that employees in Malaysia use their communication networks beyond just getting connected with their friends.The employees take the advantage both the internal and external linkages.In fact, coworker sites, as social media platform, should be used for their survival to enhance career advancement at the workplace.Therefore, senior managers need to develop a clear communication strategy, using both vertical and horizontal linkages through SNS for career development purposes.Boundary spanners, with internal and external linkages, are at a strategic position of their organizations.They should harness the information power besides depending on just relational power.Their positions are strategic for career success where they can easily forge joint venture projects with other organizations for the benefit of their own organization.
Practically speaking, networking is one of the means for having access and control over useful information at work.Therefore, it is good to provide employees with networking opportunities which are beneficial for their career success.Given the variety of methods in networking that ranged from online, offline and face-toface, it is good to diversify the networking means.Indeed, SNS could be used to enhance networking.The Social Capital Theory holds true for this study, with all the hypotheses being supported.
There are a few limitations of this study that need to be mentioned.The demographic characteristics of the respondents indicated that the majority of them are Malays.
Therefore, the findings of the study have to be interpreted with caution.This is because due to tradition among the Malaysians, especially the Malays, are inclined to rate themselves lower.They are brought up to be humble, not to project themselves.They usually hesitate to rate the highest scale, especially for their achievement.The insignificant moderating effect of SNS infers other possible moderating variables.We could speculate the role of culture and/or ethnicity for networking and information power studies in the future.Culture and/or ethnicity might have a bearing in the preferred methods of networking (e.g., faceto-face and online) that could influence the effectiveness of networking on information power.Therefore, in future studies, it is worth examining the role of culture and/or ethnicity as the moderator.
Obviously, more research is needed on networking for career development and success as communication networks, organizational contacts and communication are hastened by the use of SNS, when they are diligently used.The present study triggers more studies in this subject.SNS may be a major contributor in knowledge sharing but not for obtaining power over the information.It is plausible to see how knowledge sharing is different from information power.The former aims to share and disseminate information with others; however, the latter intends to control the dissemination of information.Future studies should look into knowledge sharing and information power.
