Life is full of change. Change can come in many forms: from a new job, to a new girlfriend or even choosing a new toothpaste. How you manage and cope with change is a sign of your professionalism and maturity.
Almost everyone finds change stressful. People like to have routines and to stick with things they know well. Change means that those routines are broken and that people have to learn new ways of doing things.
Change is such an important but stressful thing for companies that there is a whole range of professionals - known as Change Management Professionals - who can help your company through a time of change.
If changes are well planned, well executed and staff understand the reasons for the changes, it can be profitable for your company. If staff are not onside for the planned changes they can fight against the change and cause the whole plan to fail.
Explain the changes carefully to your staff and ensure that they really understand why the changes are important. That way they will feel they are part of the plan and not having some unnecessary changes forced upon them.
