Descriptive characteristics of the establishment

It is essential that once the main or reference job is identified, all characteristics should refer to that same main job throughout the questions that follow. The questionnaire design must be such that it will not confuse respondents or interviewers on that point. When any secondary activities are supposed to be recorded they must be clearly identified separately and placed so as not to confuse the flow of questions relating to the main job. The task is not usually difficult with current activity (see examples below) but can be quite difficult with usual activity.
