To the OP: It all depends on how much your store cares about your attendance as others have said. At my store, you just call in and tell them you are not coming in. They want it done at least 2 hours before your shift starts. If they detect a pattern of calling out, they can coach you. If you feel like you cant make through your shift, come to work, show them how sick you are and leave.
Sort of related and off topic, I sprained my thumb. As of right now, it still hurts to grip with my thumb. Doctor said along with soaking my thumb in warm water, I should avoid lifting anything more than 2 pounds for the next 2 weeks. My doctor didn't give me a brace.
Now, i need hours as most people do and I cant afford to not work for 2 weeks. I have a note if needed. Any advice on what to do?
