premise: The year 2003 marked a substantial shift in the working conditions of international long-distance call centre staff. This resulted from newly developed telecommunication technology as well as the change in working hours which put higher strain on employees. The typical working hours have changed dramatically to suit trans-Atlantic time zones. Throughout a shift, staff need to function dynamically and answer calls enthusiastically during unconventional hours. The late working hours has likewise caused some loss to the human interaction in the workplace in the call centre
hypothesis: Social interaction amongst call centre staff is higher when working regular hours.
