It's not that simple. Stowing OPUs is a mess at my store. And, it's going to get even worse as TPTB have decided to focus on improving lower performing fulfillment TM's productivity. More corners are going to get cut. Ideally, they should focus on improving productivity while doing everything correctly. However, in reality the fulfillment TL also owns presentation so there's not a lot of time to monitor and follow up stowing OPUs. Also, as there is no metric directly related to it, there's not a lot of incentive to make it a priority.
I've suggested to the SETLs that they need to take control of the issue. They can regularly spot check how things are being put into hold and figure out who is doing it incorrectly. Giving that info to the fulfillment TL would allow for dealing with the specific TMs and get better results than asking for it to be a general priority.
No, they haven't followed my suggestion. That would be doing something, which is slightly more difficult than complaining that some other TL isn't doing something that they have no time to do effectively.
