Cooking the books.
There's fudging things to make metrics-like pulling priorities and staging them. Then, there is changing people's time cards to make payroll, overtime, or compliance. Misusing sick time or vacation time.
Harassment. In my experience, harassers just can't stop themselves, so there could have been some prior coaching (had an ETL taken out of the store in cuffs for that).
Ridiculous as it sounds for someone making 200k, violating purchase guidelines. Holding limited edition or street date in their office. Or clearance. Reselling things.
Flat out stealing.
And, if the store is chronically red, for performance.
ETLs aren't working Saturday, but are they working Wed, Thurs, Fri?
Is the SD sick? Were the ETLs sent home because they were upset? Is there a going away thing on Saturday and there is coverage so everyone can go? Did someone close to the SD die? Funeral Saturday?
