Right? When people first start working in our industry, they use all of their PPEs and follow all personal hygiene procedures because they're afraid that they'll get sick. Then when they don't get sick, they stop using them altogether. We put up reminders that discuss the various levels of contamination that can occur throughout the workplace, especially in high risk areas. For a laugh, remind them that hand-to-mouth transmission is the usual cause of infection and watch those PPEs come back on in a hurry!
