Leaders and Changes

Whenever a new leadership takes place, there will be numerous changes introduced in the organizations. I am referring this to every firms, organizations and countries all around the world. Most importantly, do the changes they introduced help make life easier for their employees and countrymen or they are just trying to show their people that a new leadership has taken place?

When leaders make changes, do they know about the rationale behind their changes? It's good to introduce change if it makes things work better like business profits grow higher, employees' life made easier. I felt that leaders should think more thoroughly before making changes in the firms/ organizations practice. If a firm's employees have been given a standard dress code to work and people can recognize them from which company, it means the firm has successfully earned recognition in public. With such recognition in public, does a new CEO have to introduce the wearing of hat for all his employees?

Sometimes, when things are going well and smooth, it is great to stay the way it is. Changes are to be implement when things aint going right like public making complains etc. Make rationale changes and stopped showing us you can change things as you wish.. Please..
