The paper makes a case for the integration of the largely separate literatures of environmental management (EM) and human resource management (HRM) research. The paper categorizes the existing literature on the basis of Ability–Motivation–Opportunity (AMO) theory, revealing the role that Green human resource management (GHRM) processes play in people‐management practice. The contributions of the paper lie in drawing together the extant literature in the area, mapping the terrain of the field, identifying some gaps in the existing literature and suggesting some potentially fruitful future research agendas. The findings of the review suggest that understanding of how GHRM practices influence employee motivation to become involved in environmental activities lags behind that of how organizations develop Green abilities and provide employees with opportunities to be involved in EM organizational efforts. Organizations are not using the full range of GHRM practices, and this may limit their effectiveness in efforts to improve EM.

This study is the first that theorises and empirically tests, at the organisational level, the role that ‘Green’ Human Resource Management (HRM) practices play in facilitating employees' collective engagement in environment protection by taking voluntary actions that ‘go the extra mile’. In this regard, we take an original perspective on Environmental Management (EM) as an organisational change that requires strong support from employees. This allows us to investigate the mediating role of collective commitment to change – and specifically to EM – with regard to the relationship between ‘Green’ HRM practices and collective voluntary behaviours towards the environment. Our results show that ‘Green’ HRM practices are conducive to voluntary behaviours towards the environment at the collective level. Moreover, employees' willingness to support their organisation in its EM endeavour partially mediates this relationship. Additionally, by conceptualising three different types of ‘Green’ HRM practices, our results disentangle their relative importance and their differing impact on collective behaviours towards the environment. This paper thus provides scholars of EM and managers with original evidence-based guidelines on how to leverage ‘Green’ HRM to enhance employees' collective attitudes and behaviours towards the environment

We examine the relationship between HRM practices, conceptualized at the workplace level, and individual employee attitudes and behaviour. We focus on two possible explanations for the relationship: social exchange and job influence/employee discretion. Findings from a study of employees in North-East England suggest that there is a positive impact of HRM practices on organizational citizenship behaviour, through an effect on perceived job influence/discretion. There was no such effect for perceived organizational support. These findings provide support for a job influence and opportunity explanation of HRM effects on employee attitudes and behaviour.

This article examines the impact on employee attitudes of perceived age discrimination, drawing on a study of a local authority. Survey respondents report that discrimination on the grounds of being ‘too young’ is at least as common as discrimination on the grounds of being ‘too old’. Findings suggest that perceived age discrimination, whether for being too old or too young, has negative consequences for affective commitment to the organisation. Those who feel that they have been discriminated against because they are considered too old have higher levels of continuance commitment. There is partial support for the hypothesis that older workers who feel that they have been discriminated against have a stronger intention to retire early.
