"The department you have been managing has previously been two separate organizations. The two sections are recently amalgamated and the process of amalgamation has been done by top management in a non communicative and directive manner. The entire process took a lot longer than what was expected with very little information along the way."

Analysis.
The above events are not at all helpful in creating a good relations among the employees and between employees and management. If top management is in a non communicative and directive manner, they are likely to be authoritarian and dogmatic. This means they do not consult or involved the employees and it is very likely that the employees are left in the dark. When employees are left in the dark and rumours are allowed to be rife about the amalgamation, people tend to be suspicious and distrusting. With such attitudes created, the perceptions of every actions that are about to be taken by the top management will tend to be negative. Remember, perceptions are what the employees perceived from the environment. If the environment is negative, the employees will perceive in a negative way.

If the process took longer than what was expected, this means there is some inefficiency along the way. When people perceived the management to be inefficient in handling the amalgamation, they will perceive the management to be inefficient in other actions as well. Their attitude is such that they do not believe in the capability of the management anymore.
