Purpose - Workplaces are challenging environments which place workers at the risk of obesity. This is particularly true for Australian road transport industry workplaces. The Analysis Grid for Environments Linked to Obesity (ANGELO) framework is a public health tool which can be used to conceptualise obesogenic environments. It suggests that workplaces have a variety of roles (in the physical, economic, political and sociocultural domains) in responding to obesity in transport industry workplaces. The purpose of this paper is to present the findings which explore this idea. Design/methodology/approach - The project used a mixed-methods approach located within a participatory action research framework, to engage workplace managers and truck drivers in the implementation and evaluation of workplace health promotion strategies. The project involved six transport industry workplaces in Queensland, Australia. Findings - This study found that transport industry workplaces perceive themselves to have an important role in addressing the physical, economic, political and sociocultural aspects of obesity, as per the ANGELO framework. However, transport industry employees - specifically, truck drivers - do not perceive workplaces to have a major role in health; rather, they consider health to be an area of personal responsibility. Practical implications - Balancing the competing perceptions of truck drivers and workplace managers about the workplace's role in health promotion is an important consideration for future health promotion activities in this hard-to-reach, at-risk population. Originality/value - The use of the ANGELO framework allows the conceptualisation of obesity in a novel workplace context.
