I am working on a small library project in Iowa. They have only three staff members and not everyone works every day of the week. The library hours are in the afternoon for 4 days per week and in the morning on Saturday. I am wondering how to administer the survey so it meets the methodology requirements. It says that the survey should identify how the employee got to work during a 4 hour period between 4 and 11 a.m. Since there is only one day of the week where they are even open at 11 I am looking for suggestions for an alternative documentation path. Thanks!
