Travel Nurse Guaranteed Hours, Call Pay and Cancellations, Explained

By CircleRN Team | Published 2026-10-26 | 11 min read

How travel nurse guaranteed hours, on-call and call-back pay, stipend charge-backs and cancellations work, and what federal overtime rules say about call.

Guaranteed hours are the minimum a travel contract promises to pay you each week or pay period even when the hospital cancels your shift, less whatever call-offs the contract allows. Call pay comes in two parts: an on-call rate, a small hourly amount for staying reachable, and a call-back rate, a premium for the hours you actually come in, often with a minimum number of paid hours per call.

Cancellation clauses decide who carries the cost when an assignment ends early. Federal law sets none of these terms. What it does decide is how call time and call pay count toward overtime, and that part is covered here with the regulations quoted. The basics of reading a guarantee, including averaging and make-up shifts, are in the travel offer and the contract; this guide picks up where that one stops.

Who guarantees your hours: the hospital or the agency?

Usually there are two guarantees, and you only see one of them. The hospital signs a contract with your agency that says how many shifts it may cancel and whether it pays the agency for hours it cancels. The agency then writes its own guarantee to you in your assignment confirmation. The two do not have to match. If the agency promises you 36 hours but its deal with the hospital lets the hospital cancel without paying, the agency pays for your cancelled shift out of its own margin. That is why agency guarantees commonly copy the hospital's exceptions word for word.

The exceptions that show up most often:

The question to ask is direct: is this a facility guarantee or an agency guarantee, and does the agency pay me for a cancelled shift even when the hospital does not pay the agency? On CircleRN, a job page shows whether hours are guaranteed, and whether the guarantee comes with a call-off clause, where the posting supplies it.

What is the difference between on-call pay and call-back pay?

On-call pay, sometimes called standby pay, is paid for every hour you are on the call schedule, whether or not the phone rings. It is a flat hourly amount well below your base rate, because you are not working. In exchange you must answer and be able to arrive within a set time, which the contract or the unit's call policy states in minutes.

Call-back pay is paid for the hours you actually come in. Contracts commonly set it at a multiple of your base rate, such as time and a half, and many add a minimum, so a short case is paid as if it lasted the minimum. The federal regulation on call-back pay describes the same structure, using as its example an agreement that pays "a minimum of 3 hours' pay at time and one-half for any employee called back to work outside his scheduled hours." That is an illustration, not a required amount: no federal rule requires either rate.

Two details decide what call is worth. Whether the on-call rate stops while you are being paid call-back, or keeps running. And whether a second call-in during the same night gets a second minimum or is folded into the first. Both vary by contract and both belong in writing.

Does on-call or call-back time count toward overtime?

Call-back time does. On-call time usually does not, but the pay for it raises your overtime rate.

Whether on-call is work. Under 29 CFR 785.17, an employee required to stay on the premises, or "so close thereto that he cannot use the time effectively for his own purposes," is working while on call. An employee who is "merely required to leave word at his home or with company officials where he may be reached is not working." Most traveler call is the second kind. The Department of Labor adds, in its fact sheet on hospital hours, that "additional constraints on the employee's freedom could require this time to be compensated." One argument made is a very short response window, and the answer turns on the facts.

Call-back hours are hours worked. The time you spend at the hospital on a call-back counts toward the 40-hour week, or toward the 8 and 80 system if your employer uses it. A call-back on top of three 12-hour shifts is often what pushes a procedural traveler past 40. How the threshold works is in how travel nurse overtime pay works.

On-call pay goes into the regular rate. This is the part most travelers do not know. 29 CFR 778.223 gives the example of a per-period on-call payment to employees who may "come and go as they please," and says the payment "is clearly paid as compensation for performing a duty involved in the employee's job" and "must therefore be included in the employee's regular rate." In a week with overtime, your standby pay should lift the rate your overtime is computed on.

The call-back minimum usually does not. Under 29 CFR 778.221, the amount by which a call-back minimum exceeds pay for the hours actually worked is "not made for hours worked," may be left out of the regular rate, and "cannot be credited toward statutory overtime compensation." The exception is call-back that is prearranged. The regulation's test is "whether the extra work was anticipated and therefore reasonably could have been scheduled." A cath lab that calls you in for an emergency case is generally the unanticipated kind. A unit that uses call-backs to cover a busy period every week is closer to prearranged, and then the call-back pay is compensation for work.

California adds a daily rule. The Division of Labor Standards Enforcement states that California pays time and a half after 8 hours in a workday and "double the employee's regular rate of pay for all hours worked in excess of 12 hours in any workday." An employer may adopt 12-hour schedules without daily overtime through an employee election under Wage Order 5, but the same order says a health care employee who works beyond 12 hours in a workday is paid double for the excess. A workday there is any consecutive 24-hour period starting at the same time each day, so a call-back that lands inside the same workday as a 12-hour shift can be double time. One hedge matters for travelers: your employer is the agency, not the hospital. Whether a hospital's alternative schedule covers you as an agency employee depends on the facts, and if it does not, California daily overtime starts after 8 hours, not 12. Ask your agency in writing which schedule applies and how it defines the workday.

How does call work in the cath lab, IR, OR and L&D?

Procedural units run scheduled cases during the day and keep a small team on call for emergencies after hours and on weekends. The emergencies differ by unit: heart attacks in the cath lab, bleeding and stroke cases in interventional radiology, emergency surgery in the OR. Labor and delivery is staffed around the clock, so call there, where it exists, often backs up the unit when volume spikes or covers a cesarean section team. A procedural contract often looks like weekday shifts plus a call rotation on nights and weekends.

That structure is why a call-heavy contract can out-earn its own base rate. Call pays in three layers:

  1. The on-call rate for every hour on the schedule, whether or not you are called.
  2. The call-back rate for the hours you come in, often with a minimum per call.
  3. Overtime once call-back hours push your week past 40, computed on a regular rate that includes your on-call pay.

A weekly total quoted before you have a call schedule cannot tell you what call will add. To estimate it, ask four things: how many call shifts per week or pay period a traveler takes, how often the call nurse is actually called in on a typical night, the required response time, and whether you get a rest period after a long night of call-backs before your next scheduled shift. Also ask whether missing a scheduled shift after an all-night call counts against your guarantee or your stipend.

The response time also limits where you can live. A 30-minute window rules out a cheaper room an hour away, so check it before you sign a lease. Unit-specific questions are in the guides for the cath lab, operating room and labor and delivery.

Which pays more, cath lab or EP lab travel contracts, once you count call and overtime?

No public source measures this, and we have not published a separate EP lab pay figure, so there is no honest number to give. What can be said is where the difference comes from. Both are invasive cardiology labs, and both draw on the same pool of procedural nurses. The difference is usually call. Most electrophysiology work, such as ablations and device implants, is scheduled, so EP labs commonly carry lighter call or none. Cath labs keep emergency call for heart attacks around the clock.

So the comparison is not base against base. Compare each offer on its expected week: base hours, plus expected on-call hours times the on-call rate, plus expected call-back hours times the call-back rate, plus any overtime those hours create. A cath lab contract with frequent call-backs can come out ahead. An EP contract with no call can be the better choice if you value your nights, because call pay is paid for time you cannot fully use as your own. Current cath lab figures are in the cath lab pay guide.

Why do agencies tie stipends to the shifts you work?

It is common for contracts to reduce, or charge back, the housing and meals stipends for missed shifts. Some apply this only to shifts you miss. Some also apply it to shifts the hospital cancels. The reason agencies give is tax law, and that reason is half right.

The right half: a tax-free per diem is tied to days of travel. IRS Revenue Procedure 2019-48 treats a per diem as substantiated "for each calendar day" of travel away from home, and says an allowance "may be paid for the number of days away from home performing services as an employee." If you leave the assignment, or go home for a week mid-contract, those are not days away from home on business, and an agency that kept paying the full stipend would put its tax treatment at risk.

The other half: the same revenue procedure says an allowance "computed on a basis similar to that used in computing an employee's wages or other compensation (such as the number of hours worked...)" does not meet the business connection requirement and "is not a per diem allowance." A stipend cut per shift or per hour you work can look like that. The IRS has not ruled on per-shift charge-backs, and the same section accepts an hourly meals payment to flight crews, so this is a risk rather than a rule. Separately, the Ninth Circuit in Clarke, an overtime case rather than a tax case, treated a per diem cut for missed shifts as wages for overtime purposes, which is explained in the offer and contract guide.

So read how the clause is written. A reduction for days you are not on assignment has a tax basis. A reduction for each hour or shift not worked, especially when the hospital cancelled it, can look like wages for tax purposes, and the Ninth Circuit treated that pattern as wages for overtime. Ask whether hospital cancellations and your own call-outs are treated differently, and whether a charge-back is taken from a later paycheck. The tax rules themselves are in what the IRS says about housing stipends and the tax home rules.

What happens to your pay and housing if a travel contract is cancelled?

If the hospital cancels. The hospital ends the assignment under its contract with the agency, and what you receive is whatever your own contract says: a notice period, pay in place of notice, or nothing. A termination "for cause," such as a failed competency or a conduct complaint, usually ends the assignment with no notice at all. Your stipends stop with the assignment either way. Our contract red flags guide treats two to four weeks of notice from either side as the fair range, and nothing in law requires it.

If you leave early. Expect repayment of things the agency fronted, forfeiture of a completion bonus, and sometimes a penalty written into the contract. Which of these is enforceable, and whether it can be taken from your final paycheck, is state law. The offer and contract guide covers the repayment list.

Your housing. This is the exposure that outlasts the contract. The stipend stops the day the assignment ends, and a lease does not. Rent month to month where you can, ask the host for a written clause that lets you leave with notice if the contract is cancelled, and avoid prepaying more than a month. If the agency provides the housing, ask whether you owe for it if you are the one who ends the contract. More on housing for cancelled contracts is in the housing stipend guide, and what to do about the gap in pay is in extending or ending a contract.

How long are travel nurse contracts?

Thirteen weeks is the most common length, a quarter of a year. Shorter contracts of 4 to 8 weeks exist, usually for urgent needs, and so do 26-week contracts. Many 13-week contracts are extended for another block. None of these lengths comes from a rule; they are industry practice.

Length changes how much the other terms matter. On a 4-week contract, one cancelled week is a quarter of your pay, so the guarantee and the cancellation clause carry more weight, and short furnished rentals cost more per week. Ask whether orientation counts toward the contract length and is paid at the full rate. For taxes, the length to watch is cumulative: an assignment realistically expected to last more than a year in one area is no longer temporary. That rule, and how extensions count toward it, is in extending or ending a contract.

How do completion and sign-on bonuses work for travel nurses?

A completion bonus is paid if you finish the contract. A sign-on bonus is paid at the start and is often repayable if you leave early. Both are taxable wages. IRS Publication 15 lists bonuses as supplemental wages, and an employer may withhold federal income tax on them at a flat 22 percent, which is why a bonus check often looks smaller than expected.

A promised bonus also counts toward overtime. Under 29 CFR 778.211, bonuses "contingent upon the employee's continuing in employment until the time the payment is to be made" must be included in the regular rate. When the bonus is paid, 29 CFR 778.209 requires it to be apportioned back over the weeks it was earned, with extra overtime pay owed for each week you worked overtime. If you worked overtime during the contract, check that the bonus payment came with that adjustment.

Before you sign, ask whether a hospital cancellation forfeits the completion bonus, or whether it is paid or prorated when the cancellation is not your fault. A bonus spread across 13 weeks is usually worth less than the same money added to the base rate, because a higher base raises overtime every week and cannot be forfeited, while a bonus needs a later overtime true-up and can be lost if the contract ends early; the pay package guide shows how to compare them.

How do you negotiate guaranteed hours, call pay and cancellation terms?

Negotiate before you accept, while the agency still needs your yes. The hospital sets the bill rate and its own cancellation rules, so some terms are not the recruiter's to change. The agency can still choose what it guarantees you on top of the hospital's terms, how it splits the pay, and what it asks you to repay. Ask for each of these in the assignment confirmation, not in a text or a call:

What tends to move, in practice: a cap on unpaid call-offs, a call-back minimum, symmetrical notice, and the split between base and stipend. A competing written offer is the strongest lever you have, which is why working with more than one agency pays off. A recruiter who will not put an answer in writing has given you an answer.

Bottom Line

A guarantee is only as good as its exceptions, so ask who guarantees it and how many call-offs come before it applies. Call pays in layers: a small standby rate that federal rules put in your regular rate, a call-back premium for hours that count toward overtime, and a minimum that usually does not. In California, a call-back after a 12-hour shift can be double time. A stipend tied to days away from home has a tax basis; one cut for every hour not worked can look like wages, and one court has treated it that way. Get the guarantee, the call and call-back rates, the call-back minimum, the missed-shift policy and the cancellation notice in writing before you sign.
