What are the possible disadvantages of the way that Zaid used to contact respondent?

As an overseas student, Zaid Kilani chose to research downsizing in his home country in the Middle East. He was encouraged by his tutor to research downsizing in a non-Western context. Zaid decided to investigate how employees perceive the downsizing process. To delimit his research project, he decided to focus on one downsizing method that is used in downsizing the civil service in his home country. Further, he focused on one aspect of employees’ perception, which was fairness of the downsizing process.
