I went to do one yesterday and there was a merchandiser from another company there. She had set up the display the week prior, so at this point it was just reloading slippers.
It indicated in the guidelines that we might happen to see another merchandiser there and indicate that we are considered "support" for this project. It was purely coincidental that we were both there at the same time. We worked together but the other company has weekly visits scheduled at these stores, so these merchandisers sort of "own" their locations.
I am a little unclear why they are contracting with two companies on this (although I've seen that with other projects too) but at the end of the day, I did what was required of me and carried on with my life.
I will say, I wouldn't do these at base pay if it involves a full reset. Those of you that went and checked the store first, I think that was a wise move.
