This Masterclass, based on the Career Engagement Model by Deirdre Pickerell and Roberta Borgen highlighted the dynamic, ever-changing interactions between challenge and capacity. The challenge component is seen from a confluence of motivating work and meaningful opportunities, while the capacity component comprises resources, relationships, workload, well-being and fit. The intersection of challenge and capacity will result in greater engagement by the staff member and the further apart the interaction, the greater the disengagement.
