Although employees’ attitudes towards an autism employment programme may impact its ultimate success, there is limited research examining the implementation of these programmes from the perspective of non-autistic employees (i.e. co-workers and managers). This study explored the implementation of an Australian-based supported autism employment programme, drawing on qualitative data collected from 32 employees working with autistic trainees in the programme. Thematic analysis revealed three main themes. The programme benefits theme suggested that the employment programme and autistic trainees were generally viewed positively, with the programme benefitting both the trainees and the organisation, and leading to greater understanding of autism. However, negative attitudes and perceptions of special treatment contributed to programme challenges, which paralleled challenges that have been observed with other disability and diversity programmes. The design of this specific programme led to concerns about workforce integration, such as reduced opportunity for social and work integration into the broader workplace. This research extends the research on diversity management in the context of autism employment and provides practical insights into barriers and facilitators associated with implementing autism employment programmes. Lay abstract We asked 32 employees who work alongside autistic trainees for their thoughts about the autism employment programme that is running in their company. Specifically, we analysed their responses to understand how the employees perceived the autism employment programme’s implementation and outcomes. How employees within an organisation view diversity, and the nature of specific programmes to increase the inclusion of certain groups of individuals (e.g. autistic employees) in their organisation, can impact the success of these programmes. Research in other organisations has suggested that diversity perspectives that fully support the inclusion of people with diverse backgrounds in the organisation lead to better outcomes. Thematic analysis of the responses in this study revealed that the views of the employees fit three main themes: programme benefits, programme challenges and concerns about workforce integration. The programme benefits theme suggested that the autism employment programme was viewed positively. However, negative attitudes and perceptions of special treatment contributed to programme challenges, which were similar to challenges that have been observed with other disability and diversity programmes. The design of this specific programme led to concerns about workforce integration, such as reduced opportunity for social and work integration into the broader workplace. This research extends the research on diversity management in the context of autism employment, and it provides practical understanding into ways in which organisational-based autism employment programmes are more and less successful.
