2.3.1. Field Visits

With the intention of not disturbing the work routines, the store visits were planned in collaboration with the employees, and they were asked not to change their daily work routines for the visits. During the store visits, days and times were chosen to cover all parts of the work in each store, and each visit lasted for half-a–work-day. Seven employees from the FV departments (2–3 from each store) were interviewed and/or observed. Moreover, telephone conversations to follow up on the field visits were conducted, and respondent validations were executed. In total, 9 interviews, 19 observations, 3 follow-up calls and 3 respondent validations were performed. For more information about the respondents and data collection, see Table 1.

The first author conducted all interviews and observations, and in at least one of the visits to each store, the second author attended. To control for any distortion caused by the influence of any of the researchers, the findings were compared and discussed after the field visits.
