I believe that adaptability has always been a relevant skill in the workplace. Even though a larger majority of people need to be adaptable in today's workplace, adaptability has always been important for people in positions which require thinking and planning such as business management. In the 19th and 20th centuries, the majority of workers were employed in factories so adaptability was a necessary skill for few. The only thing that has changed in terms of adaptability in these centuries is that a larger amount of people need to apply it.

gives good insight into the skills needed in the 21st century.
