It depends on the work. A call center employee is paid for a mix of availability/responsiveness, and effectiveness on the call. Availability hours are lower effort and lower energy so can be stretched—-these are typically performed at lower levels of the call center tier structure. Effectiveness is most of the work at higher levels and in more sales-oriented call center/phone roles. Six hours of intense, non-stop problem solving and pitching on the phone is plenty and if there is some cost to allowing a less than good outcome on a call or opportunity, further hours can be detrimental and it may be better to have more people on shorter rotations.
