I'd normally advise you to stay home, but since it's only your third day at work I'd come in tomorrow. if you're really not feeling well at work, your boss and/or coworkers will notice pretty early on and probably send you home for the day. so you'll show that you're committed and get to leave early without leaving a bad impression

I was going to do this but when I woke up I genuinely….could not get out of bed and I was shivering so bad so I just sucked it up and texted my boss that I won’t be coming in today because I’m super sick 😭😭 I hope he doesn’t hate me
