Their "concrete" example is given by an employee who says, "Early on in my role, [my manager] asked me to pull together a cross-functional team to develop a goal-setting process."
I can't think of anything more illustrative of why engineers to be dismissive of management than strings of abstract buzzwords that conveys little information, such as "Pull together a cross-functional team to develop a goal-setting process."
That's where I stopped reading.
