The Relationship Between Workplace Learning Activities of Estheticians and Formal, Informal, and Incidental Workplace Learning and Job Performance

This study empirically analyzed the effects of workplace learning activities—specifically formal, informal, and incidental workplace learning—on job performance among estheticians aged 20 to 50. The results showed that most participants worked long hours in franchise settings and actively engaged in various types of workplace learning. Among industry-supported learning, off-site group technical training, systematic on-the-job training (S-OJT), and formal mentoring were perceived as most effective for improving job competence. For self-development, technical training, informal mentoring, and online distance education were rated highly effective. All three types of workplace learning had significant positive effects on job performance, with incidental learning showing the strongest influence, followed by informal and formal learning. This highlights the critical role of practical experience and problem-solving skills for estheticians. Ultimately, this study systematically examined estheticians’ learning experiences and empirically demonstrated their connection to actual job performance, contributing both academically and practically. However, as the data were collected from a specific region and a limited sample, the findings may not fully represent the entire beauty industry. Future research should include comparative analyses across various job areas and career levels, as well as longitudinal studies to further explore the sustainability and effectiveness of workplace learning.
