At this point, the company needs to tell him that he will be fired if he doesn’t start showing up to work clean. 

I do not know how people can go days without showering. Unless you are a newborn baby or in a life-threatening situation where there is no running water, there is no excuse for not hopping in the shower for 10 minutes a day and lathering up all over your body. You do not need 10 million different gels and conditioners to be clean, contrary to what some clean consumers believe. As long as you shower, wash your sheets, and wear deodorant, you really can’t go wrong, even in harsh weather conditions. It’s extremely easy to carry deodorant or perfume with you in your day-to-day life. It’s not rocket science. 

Some unsubstantiated rumors are going around that you don’t need to shower every day if you are generally clean in every other area of your life, and that’s just not true. You definitely do not need to wash your hair with shampoo and conditioner every day to be clean, but if the largest organ on your body goes mostly unwashed for days at a time, you shouldn’t be surprised that you stink. Just because you don’t smell it doesn’t mean that everyone else can’t, and you should be considerate of other people’s nostrils. The guy in this story probably doesn’t think he stinks as much as he does, but all of his coworkers do.
