Internal mobility is a vital way that you can retain your staff by offering them development and new opportunities. Internal mobility is when you offer your employees the chance to move around different positions in your company. This can mean either promotions or also moving to different departments in lateral roles.
A skill inventory can help you to find out who in your company has which skills. This information can then be used to suggest internal moves that may suit each person. When a position becomes vacant, you can look to fill it within the company before advertising externally for applicants.
