How do professionals learn? Does this increase employability?

The newspapers are full of it, the skill gap. We have been trained for years, but the things that really make you better in your profession and are now useful, such as digital skills, were often not included. We look at knowledge and competences differently. Flexibility is the most important characteristic of a successfully deployable employee. How are we going to equip people with the skills that will be needed in the future, and actually already needed? What does this mean for the employer and what can an employee do to be and remain successfully employable?
