Purpose: This study aims at analyzing the impact of perceptions of the fourth industrial revolution (crisis and opportunity) in the relationship between workers' career attitudes and future learning intentions. Design/methodology/approach: This study analyzed the multiple mediating effect of the perception of the fourth industrial revolution in the relationship between career attitudes and future learning intention using data of 305 Korean workers. As career attitude variables, boundaryless and protean career orientation variables were used, and perception of the fourth industrial revolution was analyzed (opportunity and crisis perception). Findings: Both workers' boundaryless career orientation and protean career orientation influenced future learning intention through the perception of opportunity for the fourth industrial revolution. This result suggested that flexible career attitudes positively recognized the changes of the fourth industrial revolution and had an effect on promoting attitude toward future learning. Research limitations/implications: The study confirmed that workers' flexible career attitudes could promote perception of opportunity rather than crisis in changing situation and strengthen their intention to prepare for the future by mediating this perception. These results suggest that lifelong learning and competency development can be reinforced by facilitating perception of an opportunities for external change for individual career development. Originality/value: Insights for personal career development were provided by analyzing the relationship between flexible career attitudes, which are increasing in importance in the modern society, and perceptions of changes in external environment.
