So I had something weird happen to me on my last shift. I got an injury while unloading. (I stepped on a nail in a floor load truck). I notified my OM as soon as it happened. We went to the Nurse's office and went through the process of first aid calling the people we needed to call etc. What was weird is my OM gave me a drug screen. Can anyone enlighten me as to why this happened since it wasn't PIT related and I didn't do the threshold of damage?
