Why Costco Closes on Labor Day While Everyone Else Stays Open
Costco shuts every US warehouse on Labor Day. Walmart, Target, Trader Joe's and Publix stay open. The gap between those two decisions is a real staffing and revenue trade-off, and it is one every business owner makes on a smaller scale.
Deciding whether to open on a public holiday looks like a small decision, and it quietly tells you a lot about how a business is actually run. Costco closes every US warehouse on Labor Day. Walmart, Target, Trader Joe's and Publix all open on their normal schedule. Both are large, profitable companies making the opposite call on the same day, and the reasoning behind each is worth understanding whether you run five people or fifty.
On the other hand, this is not really about which company is right. Costco can afford to give up a day of sales that a thinner-margin competitor may not choose to give up the same way. Each ran a version of the same trade-off, staffing cost against expected revenue against what it signals to your team, and landed somewhere different. That is exactly the trade-off a small business owner faces every holiday on the calendar.
Here is what is actually open today, why Costco is the outlier, and how to make the same call for your own business.
What's actually open on Labor Day 2026
Labor Day is a federal holiday, so government offices, courts, post offices, banks and the US stock market are closed. Standard FedEx and UPS pickup and delivery are paused too, though limited priority services still run in some areas.
Retail is different almost everywhere. Walmart and Target are open on normal hours. Trader Joe's and Publix are open too, though Publix pharmacies are typically closed even when the rest of the store is running. Costco is the exception: every US warehouse is closed, one of only seven days a year it does this, alongside New Year's Day, Easter, Memorial Day, July 4th, Thanksgiving and Christmas.
Why Costco can afford to close and most retailers can't
Costco's own explanation is straightforward: it gives roughly 300,000 hourly employees a guaranteed day off, and a company with famously low staff turnover treats that as worth protecting on purpose. The financial reasoning is just as deliberate. Costco's membership-fee model means a meaningful share of its profit is already locked in before a single item sells that day, so one lost day of warehouse traffic barely moves the year's results.
That part does not transfer to most businesses. A retailer on thin margins, or one dependent on that day's foot traffic to make payroll, is not making a bad decision by staying open. It is making a different decision because the underlying economics differ. The lesson is not "close like Costco." It is "know which position your business is actually in before deciding."
How to make the same call for your own business
1. Calculate the actual labor cost of opening, not the assumed one. Federal law does not require extra pay simply for working a holiday, but state laws and union agreements often do, and hours past forty in the week still trigger overtime under the FLSA regardless of the day. Get the real number first.
2. Check what the day has actually done for you in past years. Pull last year's receipts for the same date if you have them. A slow Monday that happens to be a holiday is a different decision than one that reliably outperforms the rest of the week.
3. Decide what the choice signals to your team, because they notice. Staff read a forced holiday shift as "the schedule matters more than I do," the same way Costco's employees read a guaranteed day off as the opposite. That signal compounds over every holiday on the calendar, not just this one.
4. Whatever you decide, say it early and everywhere. Update your Google Business Profile, website and voicemail before the holiday, not the morning of. A customer who drives to a closed store blames the business, not the holiday.
Where this leaves you
Labor Day is a small, useful test of how your business handles a trade-off it will face a dozen more times a year. Run the real labor cost, check the actual historical traffic instead of guessing, and decide deliberately. Whichever way you land, tell customers before the day arrives, not during it.
Costco and Walmart are not disagreeing about facts. They are running the same trade-off through two different balance sheets and landing in different places, which is exactly the exercise worth doing with your own numbers before the next holiday.
