The case deals with the functional and behavioral issues faced by an oil refinery shift in-charge regarding workforce management. In addition to the refinery policy requirements the behavioral constrains become extremely important for consideration. An unwanted combination of Manager-Supervisor or Supervisor-Operator can potentially decrease the performance and pose threat to the overall operations. The other parameters to be considered are extent of work, cost of overtime, fatigue level of the employees and skill composition. The methods of scheduling under these constrains are the prime focus of the case.
