Before the merger takes place, the leaders of both organizations - at least, of the dominant one - should have a strategy mapped out, including communications to employees and customers, where layoffs will take place (if any do), and how the cultures should be merged.
Power relationships
In many ways, it makes sense to consider mergers in the same light as acquisitions. It has become a truism that there is no such thing as a merger — one side will come out dominant in each function, even in the friendliest of “mergers.”
There can, in the end, only be one CEO, one head of each function, one head of each department. Therefore, we will generally consider mergers and acquisitions to be interchangeable.
Power issues should be confronted directly to avoid drawn-out conflicts and confusion for employees. Conflicts must be controlled but addressed, to avoid protracted turf wars, lasting bitterness, and employee withdrawal and retention. (Withdrawal can be psychological as well as physical - employees can simply not go that extra mile, and do the absolute minimum required of them. They can also sabotage change efforts and new initiatives. This can last for many years, long after outsiders have forgotten about the merger.)
Personal issues
In most takeovers, both companies’ staff lose some productivity (and people) as employees divert their attention to their own place in the future, merged company. Will they still have a job? Will they have advancement prospects? What will be their role? Will the company gain or lose? This is the time when the best employees may jump ship, because they will find it easiest to get jobs elsewhere — which strengthens the competition even as it weakens the integrated company.
Mergers can be a profoundly demoralizing time, especially if communications from the leaders are sparse or misleading. Many agree that the best way to handle this is to constantly communicate to everyone in
