Purpose -The focus of this study is on line managers' attitudes towards their management role in respect of employee retirement. This study has two main aims. Firstly, it explores line managers' perspectives regarding retirement management (RM): their perceived responsibility for RM, the training they have received and the degree of decision latitude they experience in RM. Secondly, the study examines the factors that affect the extent to which line managers' perceive it to be their role to influence the timing of employees' retirement decisions. This is modelled as a function of employee characteristics and line manager attributes. The purpose of this research is to inform practice by describing differences in line managers' perceptions about retirement management and identify potential sources of bias in decision-making surrounding their decision-making.Design/methodology/approach -The design incorporates two studies: a survey of line mangers (N = 129) which investigates their attitudes towards RM, and a vignette study. In the survey, line managers were presented with a list of behaviours associated with managing older workers and asked to indicate which level in the organisation they perceived to be responsible for that (line manager, human resources or both). In addition, line managers' experiences of RM training and their assessments of how much latitude they have for decision making in the area were measured.In the vignette study, 192 scenarios were created which described hypothetical older workers based on the following variables: gender, grade, health, attitude towards retirement, work enjoyment, work performance and ease of replacement. Line managers (N = 129) were asked to indicate the extent to which they perceive that they have a role to play in the timing of older workers' retirement. Information about the line managers (demographics, attitudes to retirement and experience) was extracted from the survey and included in the analysis.Multilevel logit analysis was used to model the probability of the respondents' perceptions of their role in the timing of the retirement decision. The information was combined and multilevel models were estimated, with vignettes at the lower level (Level 1) of the multilevel structure and respondents at the upper level (Level 2).Findings -Line managers recognise their own role in retirement management activities, but perceive that a number of activities are shared with the centralised HR departments. Line managers also reported low levels of training in RM but acknowledge relatively high decision latitude in responding to requests for flexible working requests. In terms of their role in the 3 timing of employee retirement, line manager characteristics, but not employee characteristics, were found to exert an influence on line managers' perceptions of their role. Specifically, the gender and age of the manager, and whether or not the manager has prior experience of managing employees over the age of 65 were substantively associated with the probability that a man...
