There isnt one. You really need to break it down yourself. There are plenty of uboats that are pretty straight forward and should work with a 50 box per hour standard. There are others that need more time. Picture frames and furniture come to mind as they have usually multi layers of cardboard and styrofoam. Some repacks take longer then others. Some bulky items dont need that much extra tume so i just give them a slight bump for a little extra leeway. I also wont schedule people an entire shifts worth of work. If i have a tm who is there 5 hours ill try and give them 4 hours of work to account for helping guests amd breaks. I make my plans as reasonable as i possibly can, check and double check to make sure every last box and repack is accounted for. Check on my team as many times as possible so i can understand if theyve had setbacks and are off pace. My team knows my expectations arent wildly off and are achievable and it makes it much less stressful for me and them. It makes them feel more comfortable to tell me that they may have taken longer then they expected to push something because a guest interrupted them, or they had a spill, ext. A strong reasonable plan is the only way to be somewhat successful in this job. I can go to my leaders every day and let them know if there is enough hours to cover the truck that day before we even start unloading and try and help cover if there isnt.
