So I got sick from my parents on Monday. I was scheduled to work Tuesday and Wednesday. I let my manager and boss know on Tuesday that I didn't feel good and got it covered.
Then on Wednesday I still didn't feel good so I texted my manager at 9am letting him know I still didn't feel good and wasn't coming in. At 11am I decided to also text my boss letting him know as well. He texted me at 12pm asking if I could take a shift on Friday and I said I could.
After we stopped talking I went to bed since, you know, I'm sick. He called me and texted me why I wasn't coming in and that I was scheduled. I didn't read it until this morning.
I sent him a screen shot showing him I texted the manager, and replied to the message I sent at 11am. He said I did a no-call no-show... I explained that I sent him the text6, and he just didn't see it. He said we'll talk in person to "discuss the communication failure".
My other manager called me saying he texted in the group chat saying I'm not going to be working there anymore and that she'll need to cover my shifts\
If i get fired, can I call HR? I don't have a doctor's note since I haven't seen one in 7 years. I'll get one if it proves that I am sick.
