Should Soldiers receive Convalescent Leave to take care of spouses?

Also as add on. Commanders have great flexibility in setting duty days and work schedules. They can have you work one hour in a week or a hundred.
If a guys wife has a serious illness or is dying I'm going to help him out and I can get my work out of him in the weeks to come, but if the situation is borderline that is what he has regular leave for and the ability to request passes.

Agreed, however what is the recourse Whe the Battalion denies this leave quotin mg the leaves and passes reg based off of con lv section not stating anything reference spouse surgeries. BDE CSM, BDE CDR Open door policy, IG.

The doctor can generate a request for you to be present as an attending. This would fall under a PTDY category and would be capped at 10 days. If the illness was very serious the commander could work with the soldier and have them come back to work for a day and out on PTDY again, but this is going to have to be an extreme illness and I would make my Soldier use up some but not all of his own leave if this is prolonged. If the family member is that sick the Soldier won't be value added at work anyways as they will be too distracted.
Another way is to have the Soldier report as usual, but give them a lot of flexibility with their schedules to attend appointments or care for their spouse. I'm sure there are unit policies, but no Army regulation defines the required length of a duty day, because the only thing that matters is mission accomplishment and not the time spent. The mission comes first, but commanders are also responsible for a Soldiers well-being and have a lot of flexibility in taking care of people.

You said a mouth full; however, the military must define "life threatening condition".
