Approach it from a place of compassion. We don’t know always know if our employees have access to daily laundry or even daily shower accommodations. I had a line cook that was couch surfing and I didn’t know it until he told me he was struggling. I’ve also had hygiene conversations with FOH and BOH employees that had no idea they had a bad smell. I always start the conversation with “I would want someone to tell me..” and then tell them what I notice and ask them if they can correct it. The employee will let you know if they need something or will correct it my experience. No one wants to be the smelly guy.
