Oh, it's the same as my store. Some of my ETLs (not all, a couple of them and my STL are great) will come and review my grids before I post and try to play favorites or make completely illogical changes. You know what I do? I simply remind them of scheduling best practice and I give them my little spiel about availability, graphs, fill percentages, etc. Their eyes glaze over and they walk away, because they mostly have no clue about any of these things. Guess who does? The TLs. They get how it works and are fair about hours.
The most frustrating thing is when they want to cut hours for a TM with performance issues instead of addressing said issues via best practice with performance conversations and corrective actions. Luckily this has been changing recently with my new ETL riding the rest of their backs to do things the right way.
