With the advent of the gig economy, learning is seen as an important issue to consider. Due to online work, the working environment is rapidly changing. Gig workers, known as online workers, provide services through online labour platforms. The success of a gig worker is dependent on an accurate portrayal of his work's creative performance. The primary objective of the current study is to investigate the impact of workplace learning activities on the creative performance of gig workers with the mediating effect of motivation. In this regard, survey data was collected from 200 gig workers working online, representing two online labour platforms. The study uses the partial least squared structural equation modeling (PLS-SEM) technique as a statistical tool. The findings provide empirical evidence to show that workplace learning activities have an impact on creative performance. Moreover, a gig worker’s motivation significantly mediates the relationship between workplace learning activities and creative performance. As a result, the current study is useful for gig workers who want to improve their overall performance through workplace learning.
