No show, no call. When an employee does not show up to work or call.

Betty got fired last week for her repeated NSNC's.

No Stats, no Chat

You expect me to respond, when you don't tell me when you were last tested for STIs. It's not on your profile either. Sorry dude, NSNC. I'm not risking us, get on top of your health. Get back to me when you know your STI status.
