Depends on store volume.
A high-vol store (A or higher) would have an:
ETL-Guest Experience (checklanes, front end)
ETL-Softlines (clothing, accessories, shoes, lingerie, etc)
ETL-hardlines I (electronics/entertainment, domestics, auto, sporting goods, toys, kitchen/small appliances, stationery)
ETL-hardlines II (HBA, comsumables, seasonal, mini-seas, pets/chemicals, home storage, home decor, Pfresh)
ETL-Assets Protection (store security)
ETL-HR (self explanitory)
ETL-Logistics (backroom, flow)
& an STL (Store Team Lead - the big kahuna).
Hours scheduled are based on productivity, sales & current needs. Or so they say...
