Write me a text to someone I work with asking them to cover my shift because I got sick. Use a polite tone.
Hi <insert name here>, I���m running a fever and my doctor recommended I find someone else to take my shift. Unfortunately it���s contagious and I���m worried that I���ll get everyone else sick if I go. Is there any chance you could step in for me? I���ll owe you one big time, but totally get it if this is too last minute. Let me know!
