Introduction</title><p>Organizations existence, survival and continuity depends on achieving their goals, and achieving goals is linked to individuals who have high confidence in their organization, its managers and co-workers, as trust in work relationships is one of the mainstays that help organizations to strengthen their effectiveness and achieve their goals, and it is one of the most effective administrative tools, because it prepares the conditions necessary for the success of organizations [<xref ref-type="bibr" rid="scirp.111379-ref1">1</xref>].</p><p>One of the most critical issues facing all organizations today is how to improve organizational trust at work. It is becoming increasingly recognized that trust in the workplace is a critical factor leading to increasing performance in organizations [<xref ref-type="bibr" rid="scirp.111379-ref2">2</xref>].</p><p>Organizational trust is one of the powerful forces in building the personality of the organization, as it encourages organizational stability and satisfaction among members of the organization, helps reduce negative conflicts and enhances effective responses in solving problems [<xref ref-type="bibr" rid="scirp.111379-ref3">3</xref>]. Organizational trust has many positive effects for both organizations and the employees. In organizations where organizational trust is ensured, employees have high morale and loyalty, which reflects good behaviour towards the organization, colleagues and managers [<xref ref-type="bibr" rid="scirp.111379-ref4">4</xref>].</p><p>There is a big link between organizational trust and organizational commitment. It’s considered as the most important entraining factors for organizational success. The most important factor in the formation of organizational commitment is trust that employees have in their organizations [<xref ref-type="bibr" rid="scirp.111379-ref5">5</xref>]. The organizational commitment is considered to be a linking or bond between organizations and individual [<xref ref-type="bibr" rid="scirp.111379-ref6">6</xref>]. Organizational commitment is the relative strength of an individual’s identification with and involvement in organization [<xref ref-type="bibr" rid="scirp.111379-ref7">7</xref>]. And high levels of commitment may cause valuable organizational outcomes. Commitment is associated with reducing absenteeism, turnover and counterproductive behavior, and organizational commitment is positively associated with job satisfaction, motivation and organizational citizenship behavior [<xref ref-type="bibr" rid="scirp.111379-ref8">8</xref>].</p><p>The performance of employees is considered as a very important issue due to the increase concern of organizational experts and human resources about the level of output obtained from workers [<xref ref-type="bibr" rid="scirp.111379-ref9">9</xref>]. Job performance can be defined as the overall expected value from employees’ behaviors carried out over the course of a set period of time [<xref ref-type="bibr" rid="scirp.111379-ref10">10</xref>]. Organizational trust and organizational commitment have importance in keeping the performance in organizations at high level and in getting desired results in terms of organizations [<xref ref-type="bibr" rid="scirp.111379-ref11">11</xref>]. Accordingly, this study seeks to test the impact of organizational trust on the employee’s performance of Mobile phone companies employees, through Organizational Commitment as a mediating variable.</p></sec><sec id="s2"><title>2.

Conclusion</title><p>This study aimed to explore the role of the organizational commitment as a mediating variable between organizational trust and employee’s performance in these organizations. The study result is that there is a statistical impact of organizational trust on employee’s performance through the organizational commitment as a mediating variable in mobile phone companies in Egypt. Accordingly, organizational trust plays a very important role in the commitment of their employees, and their intention to stay and continue to work the job. The effectiveness, success, and efficiency of organizations depend on the trust of employees with each other in organizations. Lack of trust feeling, on the other hand, tarnishes the relations in the work environment. It is not possible for people who are acting with suspicion towards each other to reveal a successful work at the end. Organizational commitment is the strongest motivator that highly affects person’s intentions to perform well, increases his efficiency, and improves his skills. Organizational commitment is important for organizations, because it is a good predictor of organizational goals and objectives, productivity, absenteeism and turnover.</p></sec><sec id="s7"><title>Conflicts of Interest</title><p>The authors declare no conflicts of interest.</p></sec><sec id="s8"><title>Cite this paper</title><p>Rahman, S.A.A., Wahba, M., Ragheb, M.A.S. and Ragab, A.A.
