Three calendars need to agree
Your warehouse may be open while a carrier follows a modified schedule. Customer support may be staffed while the warehouse manager is away. Those differences become a customer problem when everyone assumes someone else will explain a delayed order.
Build one operating calendar with separate rows for warehouse work, carrier collection and customer communication. Ask the account manager to confirm each row, including the backup contact. A holiday greeting from the provider is not an operating plan.
Use the carrier notice as a prompt, not a warehouse promise
FedEx's published 2026 holiday schedule marks November 11 as modified service and November 26 as closed in its FedEx service column. Its footnote describes early on-call and drop-box pickups, including some area closures. Separate columns cover other business units, and the schedule is subject to change. FedEx holiday schedule.
This does not confirm your 3PL's collection time or staffing. Ask the warehouse to verify the arrangement for your exact facility and service. Record who provided that confirmation and when it should be checked again. Avoid turning a national calendar into a customer delivery guarantee.
Try the plan against one delayed collection
Use this illustrative exercise before the holiday. The warehouse expects a collection at noon. At 12:15 p.m., the collection has not occurred. These times are invented planning inputs, not carrier commitments.
The warehouse lead checks whether parcels were handed over and records the evidence. The account contact tells your support lead whether the shipment is still waiting, collected or uncertain. The support lead decides which customer messages need changing. A named backup takes over if the account contact is unavailable.
The test passes only if each handoff has an owner, a deadline agreed by both teams and a place to record the result. “Monitor tracking” is incomplete when nobody owns the next customer update.
Write down the exception rules
For each holiday, document the last confirmed collection, the next planned collection, warehouse availability, support coverage and the escalation contact. Separate confirmed arrangements from provisional ones. Include a check time for provisional entries so uncertainty does not quietly become policy.
Agree who can authorize expedited replacement or another paid remedy. Support staff should not have to improvise spending authority during a delayed pickup. Equally, the warehouse should not assume it can change the shipping service without your approval.
Close the loop after the first affected day
Review a small set of affected orders together. Were the calendar entries accurate? Did the backup respond? Did customer support receive evidence before sending an update? Record failures as specific handoff changes rather than a general complaint that communication was poor.
The best holiday plan makes an ordinary absence survivable. Customers should get a clear answer even when the usual account manager is offline.
