Doesn’t the thread say that there is nowhere to unload containers to, even if there was labor? That seems like what’s causing the truck shortage - it’s not a truck shortage, it’s an empty truck shortage.
Temporarily lifting the zoning restrictions + employing chassis solely to move containers out of the yard (instead of swapping them for empties) seems like the fastest fix
Often chassis dont have cranes to (un)load containers themselves and therefore require cranes (capex heavy assets). Such cranes aren't everywhere/in surplus.
