The document discusses lifelong learning opportunities for older workers and identifies several issues that can limit their participation. It analyzes the problem from four perspectives: participating communities of practice, cultural-historical activity theory, complexity theory, and psychoanalytic theory. All perspectives emphasize examining the entire work system and social/historical factors that influence what knowledge is valued. Overall, the document calls for a critical examination of ageism and norms in the workplace to create more inclusive learning spaces that bring multiple generations together and value the strengths of different groups.
