Sick Leave & Annual Leave

Hi,

I'm thinking of calling sick. I've only got a little over 6hrs of sick leave. A full shift is normally 8hrs, right? Do you know if they will kindly take off some of my annual leave to make up for the 2 missed hours so I get paid for the full shift? I have so much annual leave accumulated. I've never called in before so idk how much hours they take off...

Plz & thx
