I went on a trip out of the country wherein I wouldn't be able to show up to work for 2 days. I had a vacation leave in a previous rotation (I am a medical intern) and for the first two days of this new rotation, I won't make it to work. The resident (my boss) has no idea that we were on a vacation leave previously so I can make up any excuse.
Today is the first day of my absence. My co-workers have covered for me and told my resident that I had the stomach flu. My resident was chill about it according to them but he told my co-workers that I'd have to message him about my absence.
Should I message him today or tomorrow? Take note that I still can't make it to work tomorrow anyway. If I message him today, how would I respond to make it seem like I still can't go to work tomorrow without sounding like an ass. Also, if I message him tomorrow, I can explain that I still have the stomach flu but it wouldn't explain why I didn't message him the day before when I first couldn't report to work.
Help a brother out!
