Strategies to commit senior subcontractor managers in participatory ergonomics interventions

The commitment of managers is one of the facilitators of participatory ergonomics (PE). However, to achieve this, practical practitioners' strategies vary depending on the organizational context and type of stakeholder and are poorly described in the literature. The purpose of this paper is to describe and to analyze the process and strategies that led to senior managers commitment during a decision-making intervention in a subcontracting context. A reflexive practice method was used to describe strategies implemented during a multi-site research project focusing on musculoskeletal disorders prevention in the meat processing sector. A 3 levels commitment method was developed which included: each subcontractor individually, subcontractors together, and subcontractors with their main contractor. Four strategies from the literature were firstly implemented: the creation of a steering committee, the identification of tendencies to act, the transfer of knowledge and moderation of collective discussion. An additional new strategy based on the sharing of a common interest - knife sharpening and maintenance was necessary to achieve the commitment. These results reinforce the importance of stakeholder strategies commitment in PE. A greater consideration for developing a valid framework is needed.
