From what I know, FOH staff would not be the reason Hoop isn’t opening yet. As far as I can tell there are still some part time BOH cast members waiting for their recall as well.I don't think the recall was area specific, only that they would put them back/get first dibs on the area they where laid off from when that area began to reopen. The problem is that 20% of people in Food and beverage did not come back. 20% does not sound too bad but when you operate at the scale Disney does its pretty significant. I don't have real numbers but lets just say my quick Google search is accurate and WDW employs 77,000 people, again for argument sake lets assume 30,000 of those people work in Food and Beverage. All 30,000 lost their jobs last year. They have since all been asked back 20% or 6,000 people chose not to return. Now management has to decide where they put those people that did come back. Should they put them at Hoop or do they staff the popcorn cart at MK? A QS at AK, TS at HS or the bar at the resorts that are open. You can see how Hoop falls down the list quickly. However as I said these are just spit ball uneducated guess numbers but if more people work Food and Bev the problem gets worse, less the problem gets slightly better but no matter how it shakes out you need more people to fill these roles.
Regardless we have a trip end of Aug, would love to spend an evening at Hoop-dee-doo. Was starting to be optimistic when I heard the cast was recalled but if these staffing issues don't resolve soon, we may not be visiting Pioneer Hall till next year unfortunately.
