Aww, thank you! So kind!
I think that I might know what you are referring to though. It is possible for a TM to use the time clock and physically work at another store if the main store charges off the TM's scheduled shifts to that other store. The TM is still tied only to the main store though so they aren't officially also a TM of that other store.
Most of the time, sending TMs/TLs to work at another store is just temporary because that other store needs serious help.
Same, one of my old TPS worked at multiple stores too. My AP Leader actually asked me to help them with the TPS schedule so I totally related to your post. 🙂
