It is the intial rack alignment each morning, keeping them aligned through the day, or something else? If it is in the morning from the cleaning crew vacuuming, then I would suggest just making sure it is the first thing the brand attendants or TL do when they walk in. Regardless of the reason, if you want it to be better consistently, make sure you take the time show and teach the tms who affect the rack alignment. This includes: flow, openers, fitting room, brand attendants, TL, and the closers. If they know the expectations and you follow-up, then it will change.
Good luck 🙂
