At my store we have a lot of team leads, sometimes 4 on a shift. Always at least 2.
No one says TLOD at my store only LOD. The other night ETL HR and GSA closed. That was the slimmest close I have seen for our ETLs. Generally always close with an ETL or GSTL up front. Multiple TLs from Starbucks, Softlines, Hardlines, AP too.
Target used to have a level of employee between TM and TL, called a Specialist. They were indicated with a "Spec" title next to their name on the grid, much like TLs have "TL".
There were specialists for every area, most of them are now called "Brand TMs". Just about every workcenter had specialists. They were assistants to the TL, and had a level of authority to them.
At least once a week at my store, there is no tl closing at all, just the Lod. But, we have our strong tm's who closed with the Lod.
