The One-Day Strike: Why Nurses Are Walking Out for 24 Hours Instead of Weeks

When people picture a nurse strike, they often imagine a long standoff, weeks of picket lines and empty paychecks. But that is not what most nurse strikes look like anymore. The most common nurse strike today lasts exactly one day.

Of the 102 confirmed walkouts in our database, at least 41 lasted a single day. That is more than 4 in 10, and it is almost certainly an undercount, since several more strikes are recorded as short, fixed-duration actions without an exact day count. The short, planned walkout has become the signature tactic of the current wave.

A one-day strike is a different kind of pressure. It costs nurses far less in lost wages than an open-ended walkout, and it is easier to sustain emotionally and financially. Yet it still forces the hospital to scramble for replacement staff, often at high cost, and it puts the dispute in the headlines. For many units, that balance of impact and cost is the whole point.

It also lowers the barrier to acting at all. A nurse who cannot afford to miss two weeks of pay can usually manage a single day. That makes it easier to get the strong strike votes unions need.

A short strike can still be an expensive one for a hospital. Even a one-day walkout forces a hospital to bring in travel nurses at premium rates, and the bills add up fast.

The per-nurse rates are steep on their own: during a 2019 strike, the University of Chicago Medical Center reported paying replacement nurses about $4,200 each to cover a five-day assignment. Scaled across a whole hospital, the totals climb fast. During Minnesota’s 2022 strike, one group of Twin Cities hospitals estimated it faced more than $20 million a day in added costs. Longer walkouts have run even higher, from roughly $25 million a week at Providence in Oregon to more than $1 billion in a single quarter at Kaiser Permanente. The clearest figure of all comes from the hospital’s own accounting: during a months-long 2023 strike, Robert Wood Johnson University Hospital in New Jersey said it had paid more than $120 million for replacement nurses. That financial pressure is exactly what gives even a brief walkout its bite.

Do not mistake short for small. Some of the largest nurse walkouts in the country have lasted just one day. In September 2019, the California Nurses Association coordinated a one-day strike across 12 Tenet hospitals in three states. Thousands of Sutter Health nurses in Northern California have staged single-day actions as well.

The Biggest One-Day Nurse Strikes

A one-day strike does not have to mean a single hospital. Some of the most effective short actions are coordinated across many sites at once, multiplying their impact without lasting any longer.

How Far Nurse Strikes Reach

The 2019 Tenet action is the clearest case, with nurses walking out at 12 hospitals across three states on the same day. Coordinated timing like that turns a 24-hour strike into a system-wide event, drawing far more attention than any single picket line could.

The one-day strike is not one tactic but two, and the difference is legal. Most one-day walkouts fall into one of two categories, and which one a union picks shapes both the protection nurses have and the message they send.

• An economic one-day strike is a warning shot in a contract fight. Nurses walk for 24 hours to show they are willing and able to strike, then return to the table with that threat now proven real. It is leverage on wages, staffing, and benefits, delivered at a fraction of the cost of an open-ended walkout.
• An unfair labor practice, or ULP, one-day strike is a different move. It is called in response to something the union says the employer did illegally, such as bargaining in bad faith or retaliating against organizers. Its key advantage is legal: nurses on a lawful ULP strike generally cannot be permanently replaced and are entitled to their jobs back, a protection economic strikers do not fully share. That makes the short ULP strike a low-risk way to protest an employer’s conduct and put it on the record.

Across our data, economic strikes are the ones that tend to end in a signed contract, while ULP strikes are typically built to apply pressure and protect nurses rather than to settle the dispute in a day. A one-day strike of either kind is usually not enough to close a contract on its own. The walkout signals resolve, then the two sides return to the table. That is why the same hospitals sometimes see several one-day strikes during one long contract fight.

The one-day strike has a limit. Because it is short, it rarely ends a contract fight on its own. Many of these walkouts send a message and then bargaining continues. Some hospitals see repeat one-day strikes over many months as a result, a pattern that shows up clearly in our data.

Still, for nurses weighing whether to act, the one-day strike has changed the math. It is a way to show resolve and apply real pressure without betting everything on a long walkout. To follow active and planned strikes, see our 2026 nurse strikes list.
