This study analyzes regular and temporary staff’s (temps’) perception of opportunities for learning in an inter-organizational project organization. Theoretically, aspects of organizational culture and dimensions of learning are combined. Data consist of a case study with mixed methods in terms of an online survey and individual interviews. The results show that male temps and female regulars are more aware of the learning preconditions than male regulars. On an organizational level, it appears to be misleading to assume that the project owner who hires staff strives for competence transfer between regulars and temps. Similarly, it is misleading to assume that the project owner takes responsibility for transferring competences between different groups of staff. At the individual level, temps tend to be more focused on their specific task compared to regulars.
