I was a senior TL back when that was a thing. I stepped down to just regular TL and stayed at the same store, despite knowing the code to the safe, and I gave up my key.
A year later I stepped down from TL and they made me transfer stores, even though I didn’t want to at the time.
A year after that, I got promoted back to TL. I had a few ETLs and SDs on my side with it, and I knew the DSD. I had to really plead my case to get the interview at all, but they nearly promoted me on the spot when the interview was over.
Two years after that (which was just a few months ago), my store was so short on key holders that they gave me a key and I had some LOD shifts on weekends. And now that my store got a couple key holders back (still short by 1), they stopped scheduling me for LOD shifts, although I still have the key to the store.
