Possibility of hub closing

Since I’ve started (been with union going on 2 years) start times have been slowly getting pushed back. For example I’m on twilight, an when I started we would come in regularly at 3:30pm-4:00pm but now around the same time of year we are coming in at 6:00pm on a Tuesday! An it’s like that for the rest of the week. Obviously the volume is low so what’s up? Could my hub be on the verge of closing down? We just finished construction on the autonomous sorts last year in 2024 before peak. I wouldn’t be worried if I didn’t see the sub filled with posts about people’s hubs closing down with 0 notice at all now they have to either drive out the way or literally start their career over. Man I have kid and finally have enough seniority for a cover driver spot.
