Division Commissioner and Guide leader here.
I give many many hours to Guiding.
In my DivC role, I would want to know if one of my units is not being run well, but so that I can put support and guidance in place for those volunteers, so not be on their backs whining at them.
If someone genuinely wants to help, I can find them a role. They do not have to be a leader, or even be a helper at meetings if they don't want. In my Division I have treasurers, admin people, researchers, event planners - all parents with toddlers/jobs/health issues which mean they can't be all singing dancing leaders- but the hours they give take the load off the leaders
If a unit is genuinely not being well run, despite support and training being in place, I would look to reassigning a leader to another role and putting a new team in if there were people available.
Just because we are volunteers does NOT mean we shouldn't have high standards, and be working towards a common standard. Each unit is different, depending on the leaders, but there should be some things common to all- in Guiding it is called the Five Essentials.
I can't imagine scouting is any different.
