How can we mitigate "Task Saturation" for NCO's and E4's in leadership roles?

This is something I have been a victim of ever since I was made a team leader while still a specialist. Now I'm not complaining on doing my job. I take a lot of pride in being an NCO. I'm very grateful I am making a difference within my organization. But I say this for others as well that have been victim to this. It really does take its toll and burns people out and puts strain on the ones who have families with them. We have squads for a reason....not to have 1 squads leadership or a single team leader/squad leader out of the entire platoon cover down on not only their tasks but other squads tasks because their deemed reliable or dependable because the others are shitbags and can't do it right or because they are always having childcare issues or appointments. It's a serious problem within the army, and I'm curious as to ways on how to mitigate this continuing issue.
