As organizations grow, layers are added to teams...in those layers is the middle management. Often, we forget how important those layer(s) are to the entire organization. Many times, they are the forgotten layer, taken advantage of layer, overworked, over-tasked, and under trained layer. They are also the linchpin layer to all things good and bad. I always challenge the bad as it isn't that layers fault, but rather those that put them there to figure it all out on their own and then coming back when things aren't going as planned.
The better plan is train first and instead of cleaning up first and then circling back. Those in middle management know exactly what I mean and for those of you in upper or senior management that recalls being in that middle layer, knows how are it is BUT why aren't more companies doing something about it proactively? Don't be that leader that promotes and doesn't train on the people side, that human side, the interpersonal side of influencing above and beyond task management.
