I'm actually not sure on this one, but covid-related catastrophe pay ended 5/31. However, there's a normal catastrophe pay that's available for closed stores under normal circumstances, though. For instance, if a store were destroyed by a tornado, or flooded, or something like that, the partners receive cat pay. I imagine that's what would apply in this circumstance, as well.

Depends on your state labor laws

No they will not pay you your scheduled hours. It’s fucking bullshit

Yes you will. Starbucks will pay disaster pay if your store was closed due to outside circumstances. Your SM should input those hours as disaster pay when doing payroll.
Call PRSC to confirm as well.

In Philadelphia and my SM told us that people are paid for what they were scheduled on the days we were closed (Monday and Tuesday). If your SM says that you're not, then I recommend calling PCC to ask.
