Are leaders too wrapped around emails that they forget about presence in the Motor Pool after Tuesday arrives? Is something broken/wrong?

I think you mean presence. But, its all subjective. Meaning, it depends on the capacity of the job they are doing. Some leadership get hung up on emails and meetings because that's how the organization is ran. But to directly answer your question:

What is being done in the motor pool after Tuesday if Command Maintenance is done on Monday and 5988s are scrubbed and faults are corrected/parts are on order? Is there any serious work being done that requires the NCO's presence? If the E6 - squad leader is busy is there not an E5 or high-speed E4 there to drive the train in the motor pool? This is where proactive and delegation in leadership fail. Most NCOs feel like they have to be everywhere or involved in everything that happens in that unit/squad/section when encouraging, delegating, and trusting our Junior Enlisted/Younger NCOs to do the job and back brief us at the appropriate time.

To better understand your question or issue can you elaborate? Here in Ft. Detrick, motor pools don't exist. So, this is coming from a different perspective. Even in my previous unit, I didn't spend much time in the mo-po because my E5s and E4s didn't want me there. But things got done beyond standards.

E-mail and cell phones did not exist while I was in. I personally cannot fathom using them during the "work day". As a Plt Ldr, paperwork was done by the Plt Guide and Plt House mouse; as a Company Commander, by the Company XO, and Company clerk. My desk was the clip board the company clerk carried papers on to get my signature.

The only time I was in my office as a unit commander was to get a cup of coffee in the morning or a uniform change. I had competent subordinates, so I didn't have to talk much, but I and the Senior SNCO at my command level, were always watching, inspecting, and counseling. We even ate morning meal and lunch together in the chow hall when the unit was in garrison. 99% of our leadership training was provided one on one. (That is not a euphemism for an ass chewing, it was legitimate critiques or "attaboys" to NCO's as appropriate)

This is a double edged sword. Leaders need to get out of the 9 to 5 mentality period. When their troops are training or maintaining they should have some influence on what is going on. While I have no issue with delegation, Soldiers need to recognize that their NCO's are just as willing to get dirty and work as they are willing to sit down and respond to emails
