CPT Kletzing:
Exactly! Sometimes a Soldier will screw-up once, and become labeled as a "problem child" and be treated as such in the future, despite any good progress that s/he makes. This gives the Soldier no motivation to improve and progress. The Soldier then feeds the leaders' bad image of him/her, which in turn encourages the leadership to put that Soldier under a microscope, looking for the smallest deficiency in order to slap him/her down again with punishment. The cycle continues until the Soldier ETSes or is chaptered out. Then we wonder why junior Enlisted Soldiers write "FTA" on every vertical surface they can find.
As leaders, we have to ask ourselves if we are being fair to our Soldiers. Does one screw-up doom a Soldier to this self-fulfilling prophecy and cycle of failure? Are we poisoning the well, making success impossible? As has been pointed out before, we have to look beneath the surface and see where repeated problems are coming from. Are there family, health, money, etc. issues that are at the root of the problems? Has the Soldier been beaten down by the cycle I described above? There is usually an answer to repeat issues in Soldiers. We are professionals and leaders. Tossing Soldiers into the garbage after labeling them "shitbags" or "problem children" etc. after poor performance does a disservice to the Soldier, your professionalism, your unit, and the Army as a whole. The Army invested in the Soldier; your failure as a leader to get a return on the Army's investment is a failure on every level.
So start talking to your "leadership challenges" and ask the right questions. What you find out may surprise you, and you may find a great Soldier under all the garbage you have tossed on him/her.
