how to read a nursing schedule/time shift

This may be a silly question, but can anyone offer me tips on how to read a nursing shift/time schedule. I don't even know which nurse is helping my patient during clinical. I guess i have 2 options..ask someone or look at the nursing shift/time schedule. They have abrreviations which i dont understand....like a circled C. And it's wirtten on dry erase board/horizontally. First, I would look @ the day/month...and then shift my eyes to the right to see the person's name and then on top of it would be day shift or night shift. It's hard to understand it..
C with a line above it means "with" but I'm not sure if that's what you're looking for...

Your best bet is to ask.. Unless you can scan the schedule on here, we really can't tell.. I would not advise you to scan anything here from work tho

The circled C likely indicates who is Charge for the shift
