A second condition for effective teacher involvement that does not unreasonably increase workloads is the reformulation of what it means to be collegial. If groups of teachers are to contribute to solving organizational problems, they need to be constantly mindful of their progress towards a solution and to hold each other accountable for that progress (Timperley and Robinson, 1998). Part of this condition involves taking joint responsibility for resolving the personal and interpersonal issues that may limit progress, including the implications of their joint actions for each others’ workloads. This interpretation of collegiality is very different from that advocated in much of the literature (Cunningham and Gresso, 1993; Weiss and Cambone, 1994) or that practised in many schools (Hargreaves, 1994; Little, 1990) where collegiality means working together and supporting one another.
