Purpose: This study aims to examine the moderating effect of supportive organisational culture (SOC) on the differential impact of work-based learning (WBL) on employee agility, ambidexterity and proactive goal generation. Design/methodology/approach: A cross-sectional survey was conducted using an online structured questionnaire with 443 respondents in Ghana. The data set was analysed using structural equation modelling. Findings: The outcomes of the study show that WBL has a significant and positive impact on employee agility, ambidexterity and proactive goal generation. However, the effect on employee agility was higher, followed by proactive goal generation and employee ambidexterity. The moderating effect of SOC on "H1," "H3a" and "H3b" was found to have a decreasing effect. Originality/value: This study augments knowledge by examining how different approaches to WBL collectively affect proactive goal generation, agility and ambidexterity. To the best of the authors' knowledge, this is the first attempt to examine the differential impact of summative WBL approaches on employee outcomes.
