If your store has an email list, your HR Business Partner (your ETL-HR's boss besides the STL) should be on there. Important personnel at the district and group level may be listed, such as your DTL, GVP, APBP, GOL, district pharmacy leader (DTL-℞?), etc.
If you don't have email access, you won't be able to reach your HRBP directly. Your best bet is to talk to your ETL-HR about your situation.
