Business Research Method Assignment:
Scenario:Job Satisfaction in the Banking Industry
Job characteristics are believed to have an impact on stress and well-being at work (Karasek & Theorell, 1990).The demands of the job on the one hand and the extent to which you have control over your own activities (decision latitude) on the other, are two factors which together define how stressful a job is. Those jobs which are high demand, but offer limited control, are considered to be high-strain and carry an increased risk of job dissatisfaction, stress and burnout.Based on this theoretical framework, the Union of Belgian Banks sent out a research call to several institutions, with a bidding process based on criteria such as quality of the proposal, timing, and – above all – budget. The aim of the research was to carry out quantitative research to measure the relationship between job characteristics and job satisfaction in all Belgian banks at individual level. But in order to do this effectively,several methodological issues needed to be resolved during the research process.First of all, a research consortium was selected to conduct the research, or more precisely, the two highest ranked bidders were asked to jointly undertake the research.This was the outcome of a political decision by the banks (‘Affiliation and conflicts of interest’), since the employers preferred one partner and the unions (employee representatives) preferred the other. The two competing research institutes, a private company specialising in stress at work and the Katholieke Universiteit Leuven (Belgium), were required to co-operate and develop a level of trust in order to conduct the research. For example, both research institutes had different ideas as to which scale should be used in the questionnaire. They could not just combine the scales or include both scales, simply because they are supposed to measure the same concept. Furthermore, this would also make the questionnaire too complex. Therefore, the research institutes had to combine their knowledge, look for compromises and jointly work on a shared vision, which is, to say the least, rather time consuming. A second obstacle that needed to be overcome was the sample.In total, 69,000 employees work for Belgian banks and it was decided that questioning all
employees would be too complicated and too expensive. Therefore the research committee, consisting of representatives of the banks, the unions and the research consortium, opted for a cross-sectional design with a fixed sample of 15,000 employees (roughly 21%; see p. 187 ‘Absolute and relative sample size’).
In this sample, the small banks were over-represented. Within each bank, the respondents were selected at random with no particular quota for gender, age or employee level. In the postal survey (see p.231 ‘Self-completion questionnaire or postal questionnaire’) several steps were taken to improve the response rate.‘Steps to improve response rates to postal questionnaire’; see also suggestions by Dillman, 1983). The survey was based on addresses which had been provided by the banks (name, language, address) and each employee randomly selected in the sample received a personalized envelope through regular mail, sent to him/her by the employer.The completed questionnaire needed to be returned (free of charge) through the internal post within each bank.There are various logistical problems. The researchers had to travel to each bank to collect the completed questionnaires and due to the fact that in Belgium, part of the population speak Flemish (Dutch) and part speak French, two versions of the questionnaire needed to be available and then carefully translated and tested for the accuracy of their translation (see also Tips and skills, p.488: ‘Translating interview data’). The questionnaires were sent to the respondents’ home addresses, a French version if the respondent lived in the French part of Belgium, a Flemish version when living in Flanders. This prompted a series of angry calls when Flemish people, living in the French part, or vice versa, received a questionnaire that was not in their native language. Furthermore, Brussels is officially bi-lingual and, to complicate matters even more, contains many headquarters in which the main language spoken is ... English! In order to minimise attrition, it was important that these respondents received a questionnaire in their preferred language. Another logistical issue was the co-ordination and control of the distributed information. The Belgian banks, who were the research financers, chose a decentralised way of working, hence organizing a ‘sensibilization campaign’ within each bank whereby the researchers had to visit all the banks to explain the theoretical framework and the outline of the research to representatives of both employers and employees.
Q1: Research consortium and involvement of the financers (banks) in research:What are the problems of using two research institutions to do the research jointly?What are the problems of the involvement of the banks in the research design and sampling?
Q2: Sample size: Is this sample size of 15,000 (roughly 21% of the employees) necessary? Discuss its relative and absolute size. What do you suggest the sample size.
Q3: Data collection in a real social context. Since this is data collection in a real social context, issues such as time, budget and politics are important. How would you deal with them? Discuss some of the decisions the researchers have made.
Q4: Sampling method. The goal of the research is to find the relationship between job characteristics and job satisfaction. Every bank was surveyed. The small banks were over-represented in the sample. Is the sampling method for answering the research questions a good one?
Q5: Bias in data collection. The purpose of this study is to find the relationship between job characteristics and job satisfaction. What are the biases in data collection?How can you reduce the bias in the data collection?
