Internal mobility is not something that can be taken for granted. Whether horizontal (equivalent position) or vertical (promotion or development), it needs to be prepared and thought through. By making their wishes known and sharing a well-considered and coherent project, employees commit themselves and play an active part in the development of their careers while helping the organisation to grow. They develop their employability and highlight the value of their skills and their ability to learn and develop. To dare to talk about your project, however, you sometimes have to remove certain taboos relating to the role of the hierarchy and the HR department.
