A manufacturing plant allows its engineers to come in at 7 A.M. plus or minus an hour but still requires them to work 8 hour days. Which of the following scheduling techniques is the firm employing?

A) flextime
B) constant employment
C) part-time status
D) flexible workweek
E) compressed workweek

The plant is using flextime, which allows employees to have some control over their schedule and choose when they come in within a certain range of time. This is different from a flexible workweek or compressed workweek, which involve working longer hours for a shorter number of days or reducing the number of days worked per week, respectively. Constant employment and part-time status are not applicable in this scenario.
