Elis and Phoebe work at United Insurance, a medium-sized insurance company with 240 branches in eight states. Elis works as a teller. Phoebe works as one of five regional supervisors, each of whom is expected to supervise a team of tellers. Elis recently received instructions from her supervisor that all tellers will be evaluated on the number of people they assist at their window per day. Serving more customers means higher performance effectiveness. However, Elis is also expected to follow the bank's number-one goal of customer satisfaction. Phoebe, on the other hand, is facing a difficult situation. Two of the regional supervisors left the bank for other opportunities resulting in significant increase in the work responsibility and time pressure for Phoebe and the remaining two supervisors.
