In these cases there is a thin line between what is right and what is not. In those moments I think that you have to stop and talk with the people of your laboratory, office or business of the subject. In places where this situation is not corrected people end up sick.
I work in a place like this today. You can feel a heavy, negative, and stressful air. I have colleagues who have left the doctorate with stress crises (dermatitis, insomnia and depression), I try to laugh, not cry LOL.
