In today's and future times, organizations need to be flexible and adaptive to changes in the environment. These organizations operate in changing conditions that have a major impact on business, the economy and the entire society. Such changes in the organization can be positive and negative for business. It is necessary to look at the possible consequences that may occur when implementing changes in the organization. Movers of change in the organization are: technology, economy, social trends and politics. Managing change is not easy or simple, but a manager, as a person who initiates and carries out organizational changes, must be able to manage them. Successful implementation of the changes leads to competitive advantage. The type of change (technology, change of people and product and service changes) also affects the resistance to change and it is obvious that the greatest resistance will cause changes that require the greatest changes in people. The organizational culture is successfully influenced by employees' attitudes. And the key elements of each business organization are people and their attitudes. Organizational culture can affect businesses differently, and employees respond differently to changes within a company.
