Blame-pushing happens so often and is rarely productive; in my estimation it's never productive and I don't like those who do it - they lack ownership and discipline. Managers, (leaders) are often ill-equipped for the task and that's happening more and more due to inclusion and diversity agendas. It doesn't happen in my organisation though, those in leadership roles have earned them through many years of doing what they do, not necessarily in the organisation but in other places. I'm a leader (manager), have been for many years and many different organisations and all I can say is it's the leaders that have to work the hardest (maybe in different ways to others) and to lead by exemplary example.
