People leave managers, not companies
I think this article misses an important point, which is that managers, or at least line managers, are often the messenger for decisions made in upper management.If I think back on the jobs I've had in the past, it's very rare for me to have issues with line managers. However, I had serious doubts about the competency of upper management in multiple companies that I've worked for.In this case, unless upper management recognise the problems that the line manager is highlighting, there's often not much more the line manager can do. Seeing as upper are (in my experience) frequently out of touch with the repercussions of their decisions, line managers should accept that they can only do what they can with what they're given (either that or leave).
