For context, he works remote and we only communicate through teams. He told me today that he's tired from heat exhaustion due to no AC in this place. I was not aware of this development until that point.
I immediately told him that he should not put his wellbeing at risk over this job. If he needs to go to the library or take a break, fine. Just don't suffer for trying to do a good job. I swear, this guy does not understand the concept of me not caring how much he gets done in a day over just getting something done. This is an internship. He should take his time to learn. I hired him specifically in his inexperience in this field to begin with.
TL;DR: Intern just casually said that he has heat exhaustion. Told him that his wellbeing is more important than this job.
