From explaining ergonomics to create and share a reference around security and health to supervising actions, we act in the training field to help people recall or improve their knowledge on real work situations before making decisions.
Understanding how work is done, how human beings work, why we all have different goals, points of views, how we are different everyday from morning till night and how my solutions are not everybody solutions... is the first way to understand how should solutions be implemented and not imposed to users and workers.
Understanding this helps designers and health and security managers in bringing better answers in their day to day work, taking more care about work conditions of the people they work with and for.
