You should definitely call out and if anything happened because of it, contact your DM.

Take the COVID coach online $1 which you're going to fail because of the fever, then call your store and offer to text them a picture of the failed test. It even says right on there "DO NOT work your shift until you are free of fever (without the use of fever-reducing medications) for 1 day (24 hours), AND your other symptoms have improved."

Does your store have you sign the covid coach sheet at the start of your shift? If you have a fever thats a primary symptom and they should have sent you on a five day paid isolation. They can get in a ton of trouble for asking you to work despite a failed covid coach.

I would go ahead and contact your store manager. It wont count as a no call no show if youre put on iso (as you should be) and if you get fired or get your hours cut for that, it goes against starbucks anti-retaliation policy and you can report it and your store can get into sooooo much trouble for it.
