I would like to request that "Unproductive subordinate using health conditions and problems outside of work as excuse and HR are no help" be reopened. It was marked as a duplicate of "I'm swamped at work and a colleague is slacking. Not sure if telling on him is professional".
The duplicate question is about someone who is very busy at work and wants an unproductive intern to help with the workload. This person is not a manager to the intern, and the intern's lack of effort is not the reason why the poster is so overworked.
The main question is about a subordinate who is being unproductive and causing increased workload on their manager. The typical answer of "It's not your job to manage" doesn't apply because the poster is the manager and it is their job to manage. The added complication is that the subordinate has medical issues which require (currently undefined) accommodations, thus preventing the manager from being able to actually manage yet still causing increased work stress.
Frankly, the two questions are so different that I'm completely baffled this even needs to be discussed. Please vote to reopen the question.
