Internal Service Recovery’s Influence on Frontline Service Employees’ Satisfaction and Loyalty

공태식 한국마케팅학회 2015 ASIA MARKETING JOURNAL Vol.17 No.2

Relatively little studies have investigated employee recovery from internal service failure, especially from the employees’ perspective. When handling customer complaints, employees must not only deal with legitimate customer demands after a service failure, such as providing an apology, rectifying the problem, and offering compensation, but they must also manage illegitimate dysfunctional customers, who may yell, threaten, and even physically harm the employee. These negative experiences can have strong effects, and employees can exhibit higher levels of stress such as burnout and emotional labor, which have been linked to dissatisfaction, tension and anxiety, reduced performance and effectiveness, and a greater propensity to leave the firm, ultimately leading to negative financial consequences for the firm. These conditions result in internal service failure and create the need to recover employees —in other words, internal service recovery. However, little research has examined this issue so far. The purpose of the current study, therefore, is to investigate the relationship between internal service recovery and employee outcomes. A pre-test, post-test between-subjects experimental design was developed. Participants were 166 part-time students who were working full-time. The average age of the participants was 36.74 years, and 57.50% of them were female. The average length of employment was 13 years. Participants were randomly assigned to one of four groups of approximately equal size. Three of the groups were subjected to an experimental situation involving an internal service failure, while one group was not exposed to failure, thereby acting as a control group. This study contributes to the service marketing literature in several ways. First, the study extends service failure and/or recovery research by examining recovery in an employee context. Second, this study attempts to measure internal service recovery and to empirically demonstrate its relationship to employee outcomes. Third, this investigation emphasizes the managerial importance of internal service recovery. For example, understanding the nature of the relationships between internal service recovery and its consequences can improve the effectiveness and efficiency of managers' resource allocation decisions.

A variety of diagnostic tests are widely applied in the field in industry to evaluate the condition of high voltage (HV) motor stator insulation. In this paper, the influence of temperature on the stator insulation diagnostic tests such as the insulation resistance, AC current, dissipation factor, and partial discharge measurements are studied and reported. The tests are performed with the HV motor stator winding temperature set between $40^{\circ}C$ to $80^{\circ}C$ in $10^{\circ}C$ intervals. It is shown that the AC current, dissipation factor, and partial discharge magnitude steadily increase with temperature, which suggests that temperature must be taken into account in the interpretation of the test results.

Solitary fibrous tumor(SFT) is a spindle cell neoplasm that usually arises in the pleura. Its involvement of the meninges is rare but increasingly being reported. Our case was a 33-year-old man who presented with clonic seizure around the right mouth angle and sensory disturbance at the right hand. Radiological studies showed a large extra-axial, dural-based mass in the left fronto-parietal region, typically isointense with gray matter and heterogeneous strong enhancement on T1-weighted images. Histologically, the tumor was composed of spindle-shaped cells growing in fascicles within the collagenous matrix. Immunohistochemical staining demonstrated diffuse CD34 positivity. Awareness of this neoplasm is necessary to accurate diagnosis.

This paper is purpose to understand the surface discharge properties of the contaminated high voltage motor stator windings. we carried out the insulation diagnostic tests for the contaminated 6.6㎸ motor in power plant. During the high voltage test, the flash-over occurred at 6.1㎸. We couldn't make sure if the ground -wall insulation was broken or it was just a surface discharge between an end-winding and the stator core. So we washed-out the stator windings with steam and dried in 110℃ during the 48 hours. and we carried out the insulation diagnostic tests and dielectric strength again. the insulation diagnostic tests are consist of the megger, the polarization index, the AC current test, the dissipation factor test and the partial discharge test. we analyzed the test results of the flash-over before and after.

항공서비스 고객의 가치창출 행동이 행복에 미치는 영향 -조직사회화의 조절효과를 중심으로-

공태식 ( Tae Shik Gong ),정정윤 ( Jung Yun Jeong ) 한국항공경영학회 2016 한국항공경영학회지 Vol.14 No.1

본 연구는 고객의 가치창출 행동과 고객의 행복의 관계에 고객 조직사회화 정도가 어떻게 영향을 미치는지를 조사하였다. 항공서비스 산업을 비롯한 전반적인 서비스 경제의 발전에 따라서 고객의 가치창출 행동에 대한 중요성이 계속 강조되고 있다. 고객은 수동적인 구매자가 아니며 능동적인 가치창출자로서의 역할을 수행하고 있다. 또한, 이러한 가치창출 행동은 고객만족을 넘어서 고객의 행복에 궁극적으로 기여하는 것으로 문헌에서는 알려주고 있다. 하지만, 기존 연구에서는 이러한 고객의 가치창출 행동이 고객의 행복에 미치는 영향에 어떠한 변수들이 영향을 미치는 지를 조사하지 못하였다. 이러한 조사는 중요성을 가지는데, 항공서비스 관리자들이 고객의 가치창출 행동의 효과를 어떻게 효율적으로 관리할 수 있는지에 대한 중요한 시사점을 제공할 수 있기 때문이다. 따라서 본 연구에서는 이러한 이론적 배경을 바탕으로 하여 항공 서비스 고객의 조직사회화 이론에 근거하여 식별된 세 가지 변수 즉, 고객능력, 역할 명확성, 목표일치성을 고객의 가치창출행동과 고객행동간의 주효과에 대한 조절변수로 개념화하였다. 본 연구에서 고객의 능력이란 고객이 자신의 가치창출 행동을 새롭게 학습하고 가치창출자로서의 새로운 도전적인 역할을 자신감이 있게 받아들이는 정도로 정의한다. 역할명확성에 대해서는 고객이 가치창출자로서 자신이 수행해야 만하는 업무에 대한 이해의 정도로 정의한다. 서비스 제공자와의 원활한 상호작용은 성공적인 고객가치 창출에 필수적이며 이는 경험을 통해서 획득될 수 있다. 그 결과 고객은 역할명확성이 강화될 수 있다. 마지막으로, 본 연구에서 목표일치성이라는 개념은 고객의 개인적인 목표와 가치가 서비스 제공자의 목표와 가치와 일치하는 정도로 정의하고 있다. 서비스 제공자와의 목표일치성이 높은 고객은 가치창출행동의 유효성을 증대시킬 수 있다. 실증분석을 위해 항공서비스 이용고객을 대상으로 설문을 실시하였으며 응답 자료를 바탕으로 partial least square(PLS) 분석을 통해 조절효과를 검증하였다. 자료수집은 인천공항 출국장에 도착한 고객들을 대상으로 하였으며 설문조사의 목적을 간략히 설명한 뒤 설문 조사에 참여할 의향을 확인한뒤 설문지를 배포하여 현장에서 설문지를 작성하도록 하였다. 성실한 설문조사 참여를 유도하기 위해서 소정의 상품권을 지급하였다. 총 130부의 설문지를 바탕으로 자료를 분석하였다. 응답자의 인구 통계학적인 특성은 남성이 68%이며 연령대는 30대가 가장 빈도가 높은 것으로 나타났다. 여행의 목적과 관련해서는 사업목적이 40%로서 관광 목적보다 적은 것으로 나타났다. 분석 결과, 세 가지 변수 모두 통계적으로 유의하게 주효과를 조절하는 것으로 나타났다. 이러한 결과는 항공서비스 관리자들에게 다음과 같은 실무적 시사점을 제시하고 있다. 먼저, 고객의 가치창출행동의 유효성을 증대시키기 위해서 고객의 능력을 향상시켜야 하며, 이를 위해 자사의 직원과 마찬가지로 고객을 대상으로 한 교육 훈련 활동이 필수적임을 강조하고 있다. 또한 고객의 역할을 명확하게 인식시켜 주기 위해서는 통합적마케팅 커뮤니케이션 활동을 적절히 조정해야 한다. 마지막으로 시장세분화 및 표적화를 통해서 자사의 역량과 목표와 가장 잘 부합하는 고객을 선정하여 고객의 목표 일치성을 극대화해야 한다는 실무적 시사점을 제시하고 있다. This study investigates the moderating role of customer ability, role clarity and goal congruence on the relationship between customer value creation behavior and customer happiness. Especially, chosen moderating variables are based on customer organizational socialization theory. The development of service industries, which include the aviation service, emphasizes the importance of active role of customer. In other words, customers are required to participate at value creation behavior rather than engage at passive buyer behavior. Furthermore, the literature argues that customer value creation behavior contributes to their own happiness, just beyond customer satisfaction. However, the previous research has ignored the investigation of these relationships and more importantly, the role of moderators that relates to this relationship. The investigation on moderators is important because it directly provides managers how to maximize the positive effect of customer value creation behavior on customer happiness. Therefore, the present study focuses on the investigation of the moderating role of customer organizational socialization such as customer ability, role clarity, and goal congruence on the relationship between customer value creation behavior and customer happiness. This study defines customer ability as the extent to which customers accept their role as value creator, although it could be challenging and requires learning new skills as value creators. In addition, this study defines role clarity as the extent to which customers understand their role as value creators. The successful interaction between customers and service providers are key to success for customer value creation. The accumulated experiences with service providers will enable customers to gain enhanced role clarity. Finally, goal congruence is defined as the extent to which customers`` role and service provider``s role are similar in terms of value creation. The customers who share similar value with service providers are more likely to enhance the effectiveness of customer value creation behavior. The survey was distributed to the customers`` of airline passengers and 130 responses were used for partial least square(PLS) data analysis. Participants were approached and asked to whether they have intention to participate at the survey. Those who show interests in the survey were provided the questionnaire and they filled out it on the desk at the airport. To increase the valid responses, the participants were given a gift certificate. In terms of demographic characteristics, the 68% were male and mean age level are 30``s, and the purpose of travel is the business (40%), while the leisure is 60%. The findings show that all three moderators significantly moderate the relationship between customer value creation behavior and customer happiness, which support all research hypotheses of this study. The results have several implications for practitioners. First, managers need to train their customers so that customers`` ability could be enhanced. Second, managers might want to modify their integrated marketing communication activities so that customers could have role clarity. Finally, managers need to be aware of the importance of fit with their targeted customers.
