As of November 9, 2026, more than 255 warehouse workers at Associated Grocers Northeast have been on strike since early November, and no delivery trucks are leaving the Pembroke, New Hampshire distribution center. AGNE supplies more than 600 independent stores across eight states and runs 14 supermarkets of its own. Member stores have started telling customers they will be out of some products. The episode is a live test of something most availability plans assume away: what happens when the warehouse itself stops.
What one warehouse outage does to 600 stores
A distributor outage is different from a product shortage. In a product shortage, one item disappears and shoppers substitute. In a distributor outage, the entire assortment stops arriving at once, and substitution has nothing to fall back on inside the store. The union statement says deliveries across New England and New York are already disrupted; member stores quoted by local outlets describe losing supply within days, not weeks.
| Entity | Scale | What it means for availability |
|---|---|---|
| AGNE warehouse | More than 255 striking workers | Receiving, picking and loading all slow or stop |
| Member stores | More than 600 independents | Weekly delivery cycle breaks immediately |
| Corporate stores | 14 supermarkets in two states | Same supply base, different priority |
| Geography | Eight states, New England and New York | No single regional substitute exists |
The numbers explain why the shock travels so far. One facility in Pembroke serves stores in eight states, and the co-op also operates 14 supermarkets of its own, nine in Vermont and five in New Hampshire. Those corporate stores compete with the independents they share a supply chain with, which makes allocation decisions during an outage unusually visible.
Availability plans assume a working DC
Most availability reporting starts at the shelf and works backwards. It measures whether an item is present, then traces the gap to a delivery, an order, or a listing. That chain has a hidden assumption: the distribution center is functioning. When it is not, the same report shows empty shelves everywhere at once, and store-level fixes cannot help.
The practical lesson is that supplier concentration belongs in the availability model, not in a risk register that nobody reads. A store that receives 90 percent of its assortment from one warehouse has a single point of failure, and its in-stock rate is really a measure of that warehouse's uptime.
- ConcentrationShare of assortment arriving from a single warehouse.
- FrequencyDays until the next delivery, per store.
- SubstitutionWhether a published rule exists before the shortage.
Substitution rules decide who loses the sale
When a full delivery is missed, the question stops being which item is out and becomes which shopper leaves without buying anything. Stores that publish substitution rules in advance, for example automatically upgrading to a larger pack at the same price, keep more of the basket. Stores that leave the decision to the shelf keep less. The rule matters more than the depth of the shortage.
Delivery frequency sets the recovery clock
A store on a weekly delivery cycle has no buffer once a truck is missed; the next chance to recover is seven days away. A store on a twice-weekly cycle has three or four. This is why the same outage produces very different outcomes across a network, and why delivery frequency should be reported next to availability rather than buried in operations.
Modelling supplier risk before it happens
The useful exercise is not predicting a strike. It is ranking stores by how quickly they run out if their main supplier stops for seven days. That ranking can be built from three fields most retailers already hold: delivery frequency, share of assortment from the primary warehouse, and local alternative supply. The output is a short list of stores that need a contingency plan first.
Contingency plans also need an owner. In this dispute the company says it has one in place, and stores are handling communication themselves, which produces inconsistent messages to shoppers. Assigning a single owner per region, with a standard message and a substitution rule, is cheaper than losing the basket.
FAQ
Why does a warehouse strike hit availability faster than a product shortage?
A product shortage removes one item and shoppers switch. A warehouse outage stops the entire assortment at once, so there is nothing inside the store to substitute with. The store's in-stock rate falls across every category in the same week.
What data is needed to rank stores by supply risk?
Three fields are enough to start: delivery frequency, the share of assortment supplied by the primary warehouse, and whether a local alternative supplier exists. Days-to-empty can be estimated from current sell-through.
Does store size predict which stores run out first?
Not reliably. Delivery frequency and supplier concentration explain more of the variance. A large store on a weekly cycle can run out faster than a small store receiving twice a week.
How should substitution be handled during an outage?
Publish the rule before the shortage. A simple rule, such as upgrading to a larger pack at the same price, keeps more of the basket than leaving the decision to store staff under pressure.
