Those are different scenarios, though. The STL should be communicating with all LODs so they understand how to lookup sales and payroll as well as priorities for replacing call outs.
That is not the same as a SrTL delegating a task to an ETL during an LOD shift, which is totally acceptable. My job as LOD is to ensure I run the best possible store. If I run out of hourly hands and have an urgent need, sorry ETLs, but the needs of the store come first.
