Schnowzer:
"Dissatisfaction of the workers with their treatment by the management is to be counted among the most important causes of low morale, for it is common knowledge that men tend to hold back and to do little as possible for those against whom they feel a grievance."
Sumner H. Slichter
Interesting studies in the field of worker morale indicate that although wage cuts will lead to lower morale, equivalent wage increases do not improve morale.....that requires a change of management.
