Modern Janitorial Cleans Buildings for The Marshfield Clinic and Modern Must not Drug Test Employees..If so, they would realize that their Employees are not clean. I know this because i have witnessed Modern Janitorial Employees smoking Marijuana outside of several Marshfield Clinic Buildings inside their vehicles. I had walked past their cars while they were siting in them late at night and could clearly see the use of illegal substances and a very strong oder of burnt Marijuana. This is clearly a very serious issue and some kind of action should be taken.
