1/ if you want to use this way to write your email see my correction. 2/ If you use this way, you are basically asking permission. If you are really suffering, then you should just tell them you have to go. Something like this: Hi team, Sorry, I need to leave around 3 pm today. My cold and headache are getting worse and worse. If I don't do something about it now, I'll probably be absent tomorrow. Apologies Yatin
