Sustainable “green citizen” mechanism: a micro-level theorisation of newcomer socialisation, person–organisation fit and organisational identification

Purpose This study aims to redirect the sustainable development conversation from a largely macro-level focus to a micro-level, individual-centred viewpoint within organisational contexts. It also aims to conceptualise the integration of sustainable practices at the employee level by introducing the concept of a “green citizen”. Design/methodology/approach Drawing from the literature on newcomer socialisation, person–organisation fit and organisational identification, the paper formulates propositions and suggests an initial model for nurturing “green citizens” within organisations. Findings It is suggested that sustainable development in organisations can be effectively promoted through sustainable hiring practices and specific socialisation processes that enhance strong organisational identification and value alignment. Research limitations/implications By emphasising the role of individual organisational members in promoting sustainability, this study opens new pathways for micro-level research on sustainable development. This encourages researchers to investigate how organisational practices and employee experiences interact to influence sustainable outcomes at the employee level. Originality/value The authors offer a novel theoretical contribution by linking macro-level sustainability standards with micro-level organisational behaviour. This opens a new perspective on embedding sustainability into the organisational framework, moving beyond policy and structure to emphasise individual agency and identity.
