Oh this is one of the tough ones.

Should I tell my coworker that he smell bad? One of my coworker who s kinda good with me he smells bad, seriously i can tell which aisle he passed which way he went just by follow the trail of his body odor…. I don t know how to tell him without being rude or making him feel bad about it.

Oh…that sounds bad.

Okay, so I think you should not say anything to him. Take it to the boss. The boss will have to reinforce proper hygiene stuff in the workplace. There’s no way you can say something without hurting the guy’s feelings. Let the boss handle it. Well, that’s what I would do. I prefer no confrontation.
