Should an officer be allowed to continue to serve on Active Duty after being relieved from command?

No, he should not be “encouraged” to separate or retire early, he should not be given an option! If you have been relieved of command, your case should be immediately reviewed by an impartial panel of officers. If it is determined that the removal was justified then you should be retired, or separated.

Sure

No! If an officer is too incompetent to lead, maybe they shouldn't be in the service! Officers, for far too long, have been exempt from punishments, often meted out to the enlisted... they don't hesitate to burn a nonrate, for even the least egregious offences! No, it's time they face the same punishments, the enlisted do... this'll piss off a few, but it needed to be said!

Officers are to lead, while in command or staff! If that measure is not met remove from active duty now not later!,,,

Up or out just like enlisted.

People have different temperaments and leadership skills. Running an organization where “one size fits all” has often lead to disaster. Evals can be written to reaveal strengths and weaknesses, or they are “walk-on-water” reports which reveal essentially nothing of value. Evals which would honestly hover between 3.4 and 3.8 should not be destructive to a career, but it is. ‘Had an ET SCPO who was an ace technician, but was promoted from CPO, which he loved. The promotion removed him from the hands-on aspect of his rating, and he hated being SCPO. He had little patience with paperwork tedium.
So, no. Officers in higher positions need to do their jobs and do some honest and effective evaluating.. there are many officers who have no talent in being assigned Line Officers.

Some people March in the parade, some wave from the sidewalk. Both jobs are important.

Had 1 that was harmful to his enlisted 3 injury by him for being stupid

I think everyone in every branch of service has known someone on the career path that they were convinced couldn't hack it anywhere else. It's not only common now, but so common throughout history that it's become a trope. Rare are the military sagas that don't have a Lt. Dike or a "Captain America" somewhere. But getting rid of them is always going to be a function of the higher chain of command, based on their observations of said individual's performance, and the performance of the unit. I don't think ANYONE in a leadership position could survive if their career depended on a handful of highly subjective opinions of subordinates.

No they shouldn’t the Army is real fast to kill an NCOs career but love to protect their officer core.
