Working while sick

Mostly just ranting… I asked to go home the other day because I felt feverish; my friend got me sick. I was called later that day with my manager saying “hey heard you weren’t feeling good but I need you to finish your server certification so I just put you on the schedule for tomorrow and the day after.” I’m fighting for my god damn life and still come in. They’re surprised I’m not on my A game and that “the customers can’t hear me”. I TOLD YOU GUYS MY THROAT IS KILLING ME AND IM NOT FEELING WELL?!!!! THEN THEY TELL ME TO JUST KEEP DRINKING TEA AND THEY’LL SEE ME TOMORROW?!!! WTF
