Mega Manufacturing's corporate headquarters requires specific classes in the green policies that it embraces. The HR department conducts the classes and is run as a profit center with each plant manager paying a transfer price per employee taking the classes. Recently, some of the plant managers have been hiring outside firms to conduct these classes. HR has complained to corporate that they will have to lay off staff if this continues. Plant managers reply that the outside firms are of the same quality, but less costly. Should corporate consider banning the use of outside firms and if so, under what circumstances?
