Healthcare payroll compliance comes down to three pay types most systems get wrong: on-call pay, callback pay, and sleep time. Healthcare never stops. Patients need care at 3 a.m. the same as 3 p.m., and that means hospitals, nursing homes, and home health agencies regularly ask workers to remain available outside their scheduled shifts. These rules govern exactly when those hours become compensable, and the answers are more complex than most healthcare payroll systems are configured to handle.
Misconfigure any one of these pay types and you are likely looking at unpaid overtime, undercounted hours, and back-wage liability that compounds quickly across a large workforce. The Department of Labor’s Wage and Hour Division issued a dedicated fact sheet (Fact Sheet #53) specifically for the healthcare industry, identifying the exact scenarios where facilities get this wrong.
This guide defines each pay type under the Fair Labor Standards Act (FLSA), explains when time is compensable and when it isn’t, walks through the payroll configuration requirements, and closes with a compliance audit checklist tailored to hospitals, nursing homes, and home health agencies.

On-Call Pay, Callback Pay, and Sleep Time: Definitions and Trigger Rules
These three pay types look similar from the outside. All involve employees being available or working outside their standard schedule. But they trigger compensability under entirely different rules. Conflating them is the single biggest configuration error healthcare payroll teams make.
On-Call Pay: When Availability Becomes Compensable Time
On-call time is the period during which an employee is required to be reachable and available to work but is not actively performing job duties. Whether it counts as compensable hours worked depends on one central question: is the employee’s time truly their own?
On-call on premises (usually compensable): If an employee is required to remain at the facility, whether in an on-call room, a break room, or anywhere on-site, that time is compensable work time. The employee cannot use the time effectively for personal purposes, which is the FLSA’s controlling standard. DOL Fact Sheet #53 states this directly: an employee required to remain on the employer’s premises, or so close that they cannot use the time effectively for their own purposes, is working while on-call.
On-call at home (usually not compensable): An employee who is permitted to leave a message where they can be reached, by cell phone or pager, and is otherwise free to use their time for personal activities is generally not working while on-call. The mere fact of carrying a phone and being reachable does not make the time compensable.
But “usually” is doing real work in both of those statements. Home on-call can become compensable when restrictions pile up: a requirement to respond within five minutes, a geographic restriction that confines the employee to a small radius, very frequent call volume that disrupts any meaningful personal activity, or a combination of restrictions that, taken together, prevent the employee from using the time for their own purposes. Courts look at the totality of circumstances. No single factor controls.
| On-Call Scenario | Compensable? | Why |
|---|---|---|
| Required to stay in hospital on-call room | Yes | On premises; cannot use time for personal purposes |
| Must respond within 5 minutes and stay local | Likely yes | Geographic restriction plus response time combine to restrict freedom |
| Carries pager, 45-minute response window, free to travel locally | Generally no | Adequate freedom to use time for personal purposes (see DOL Fact Sheet #53, Example #12) |
| Carries phone but calls are rare and response window is flexible | Generally no | Minimal restrictions; can engage in personal activities |
| Frequent calls, cannot leave small geographic radius | Likely yes | Frequency plus geography together prevent effective personal use |
How Netchex handles it: Netchex allows on-call time to be tracked as a distinct earnings code, separate from regular hours and callback hours, so that when on-call time is compensable, it flows into hours-worked calculations and overtime automatically. When it isn’t compensable (home on-call with adequate freedom), it can be tracked for policy purposes without feeding into overtime. The distinction is configurable, not hardcoded.
Callback Pay: Always Compensable from the Moment of the Call
Callback pay applies when an employee has completed their regular shift, left the workplace, and is then called back in to perform work. Unlike on-call time, where compensability depends on the degree of restriction, callback time is always compensable from the moment the employee receives and accepts the call.
That includes travel time from home to the facility when the callback is for an emergency or unscheduled return. Under the FLSA, travel that is part of the employee’s principal activity, such as responding to a callback, counts as hours worked. Fact Sheet #53 specifically identifies inter-facility travel time as compensable for healthcare workers.
Minimum callback guarantees: Many healthcare facilities and collective bargaining agreements include a minimum hours guarantee for callback situations, often two or four hours of pay regardless of how long the employee actually works. While federal law doesn’t mandate these minimums, state law or employment agreements may, and Netchex can be configured to apply them automatically.
⚠ Common Configuration Error
The most common callback pay error in healthcare payroll: treating callback hours as a flat bonus or separate “callback stipend” rather than as actual hours worked. When callback time is paid as a flat amount and not counted as hours worked, it gets excluded from the regular rate of pay calculation. That means the overtime premium for any workweek in which callback hours pushed the employee over 40 hours is calculated on the wrong base rate, which is an FLSA violation. Callback hours must be counted as hours worked and included in the regular rate before overtime is applied.
Sleep Time: The Rules for Shifts Over 24 Hours
Sleep time rules apply specifically when an employee is required to be on duty for 24 hours or more. This situation arises regularly in home health care (live-in aides, 24-hour shifts), nursing homes (overnight residential workers), and some long-term acute care settings.
The default rule is straightforward: all time an employee is on duty is hours worked and must be paid. But the FLSA provides a narrow exception for shifts of 24 hours or more.
| Shift Length | Sleep Time Rule |
|---|---|
| Under 24 hours | No sleep exclusion. All time on duty is hours worked, even if employee sleeps when not busy. |
| 24 hours or more | Up to 8 hours may be excluded IF: written or implied agreement, adequate facilities, and employee can usually get 5+ consecutive hours of sleep. |
| 24 hours or more (sleep frequently interrupted) | Exclusion does not apply. Entire sleep period is hours worked. |
| 24 hours or more (employee sleeps 9+ hours) | Maximum 8-hour exclusion still applies. Hours beyond 8 must be counted. |
The Three-Part Sleep Time Exclusion Test
Under 29 C.F.R. § 785.22, an employer may exclude up to 8 hours of sleep time from a 24-hour-or-more shift only if all three of the following conditions are met:
- Agreement: There is an expressed or implied agreement between the employer and employee to exclude the sleeping period from hours worked. Best practice is to have this in writing.
- Adequate sleeping facilities: The employer furnishes adequate sleeping facilities. The FLSA does not define “adequate,” and the DOL says it depends on the specific circumstances.
- Uninterrupted sleep: The employee can usually get an uninterrupted night’s sleep. The DOL requires at least 5 consecutive hours of uninterrupted sleep for the exclusion to apply.
Even if all three conditions are met, the exclusion is capped at 8 hours, even if the employee sleeps longer. And every interruption to sleep for work duties must be counted as hours worked separately.
The exclusion collapses entirely if sleep is too disrupted. If interruptions are so frequent that the employee cannot get at least 5 consecutive hours of sleep, the entire sleep period, including hours the employee actually slept, becomes compensable hours worked. This is not a minor technicality. A home health aide who is woken up multiple times a night for patient care may be entitled to compensation for the entire overnight period.
How Netchex handles it: Sleep time configuration in Netchex allows you to set up the exclusion as a conditional rule, applying it only when the employee’s shift meets the 24-hour threshold and only when interruptions during the sleep period fall below the threshold that would collapse the exclusion. If a worker’s sleep period is interrupted to the point that they cannot get 5 consecutive hours, Netchex can be configured to count the full period as hours worked. That is the kind of conditional logic most payroll systems don’t support natively.
How These Pay Types Feed Into Overtime: The Regular Rate Problem
Getting the classification right for on-call, callback, and sleep time is only half the compliance picture. The other half is overtime, specifically the regular rate of pay calculation.
Under the FLSA, overtime must be paid at 1.5 times the employee’s regular rate of pay for all hours worked over 40 in a workweek. The regular rate is not the base hourly wage. It is total compensation for the workweek divided by total hours worked. That means any on-call stipend, callback pay, or shift differential paid during the workweek must be included in the regular rate before overtime is calculated.
⚠ Common Configuration Error
The most common overtime misconfiguration in healthcare payroll: a separate earnings code for callback pay that is excluded from the regular rate calculation. Example: a nurse earns $30/hr base and works 42 hours in a week, including 3 hours of callback at a flat $45/hour callback rate. If the payroll system treats the $135 callback payment as a flat bonus excluded from the regular rate, the overtime premium is calculated on $30/hr only. The correct calculation includes callback earnings in the regular rate, which changes both the rate and the overtime amount owed. This error is common precisely because payroll systems often treat special pay codes as excluded unless explicitly configured otherwise.
What Must Be Included in the Regular Rate
- On-call stipends paid for compensable on-call time (on-premises standby) must be included
- Callback pay for all hours worked during a callback must be included
- Shift differentials (evening, weekend, charge nurse premiums) must be included
- Non-discretionary bonuses, including attendance bonuses and production bonuses, must be included
What does not need to be included: Gifts, discretionary bonuses, and certain premium pay types specified in the FLSA (such as true overtime premiums at 1.5 times for hours worked on a non-overtime day under a collective bargaining agreement) may be excluded. But any payment that is conditional on performance or hours worked is almost always part of the regular rate.
How Netchex handles it: In Netchex, every earnings code can be configured to either include or exclude from the regular rate calculation. For on-call and callback earnings codes, inclusion in the regular rate is the correct default for most healthcare settings. The Netchex FLSA overtime engine recalculates the regular rate each workweek based on total compensation and total hours, so if a callback week looks different from a standard week, the overtime math adjusts automatically.
Payroll System Setup: Earnings Codes, Configuration, and Common Errors
The compliance rules are clear enough on paper. The failure point for most healthcare payroll teams isn’t understanding the rules. It is translating them into a payroll system that was configured years ago, often by someone who has since left, using earnings codes whose behavior no one has audited recently.
The Earnings Code Architecture for Healthcare On-Call Pay
A properly configured healthcare payroll system needs at minimum the following distinct earnings codes, each with specific settings:
| Earnings Code | Feeds Hours Worked? | Included in Regular Rate? |
|---|---|---|
| Regular hours | Yes | Yes |
| Overtime (1.5x) | No (already in hours) | No, the premium is excluded |
| On-call, on premises (compensable standby) | Yes | Yes |
| On-call, at home, non-compensable (tracking only) | No | No |
| Callback hours worked | Yes | Yes |
| Callback minimum guarantee premium | No | Yes, nondiscretionary |
| Sleep time, excluded (when exclusion applies) | No | No |
| Sleep time, interruptions worked | Yes | Yes |
| Shift differential (evening/weekend) | No | Yes |
How Netchex handles it: Netchex earnings code configuration includes explicit flags for each of these scenarios: whether an earnings code feeds hours worked, whether it’s included in the regular rate, and whether it’s subject to FLSA overtime. During implementation for healthcare clients, the Netchex team audits existing earnings codes and configures new ones to match the correct behavior for each pay type, so you are not discovering a misconfigured on-call stipend code during a DOL investigation.
The Three Most Common Configuration Errors
Error 1: On-call stipend excluded from regular rate. Many healthcare facilities pay a flat “on-call stipend” for each on-call shift, say $50 per on-call shift regardless of whether any calls come in. When this is coded as a flat bonus excluded from the regular rate, the regular rate understates actual compensation, and overtime is underpaid in any week where on-call pushes total hours over 40. If the on-call time itself is compensable (on-premises), the stipend must flow into the regular rate.
Error 2: Callback hours tracked but not counted toward weekly overtime. Callback shifts are sometimes entered in a separate time entry screen or tracked on a different pay period cycle from the employee’s regular schedule. If the system doesn’t aggregate callback hours with regular hours in the same workweek, the 40-hour threshold is never triggered on callbacks alone, meaning overtime premium pay is missed every time a callback pushes a worker over 40 for the week.
Error 3: Sleep time exclusion applied unconditionally. Some healthcare payroll systems are configured to always deduct 8 hours of sleep time from 24-hour shift workers, regardless of whether the employee had an uninterrupted sleep period. If a home health aide or nursing home resident aide is regularly woken up for patient care during the night, and the system is still applying the 8-hour exclusion, the employer is underpaying hours worked every single shift. This is a systemic, recurring violation, not an isolated error.
Compliance Audit Checklist: Hospitals, Nursing Homes, and Home Health Agencies
The DOL’s Fact Sheet #53 identifies the consistent failure points in healthcare payroll. Use the following checklist to evaluate your current practices against each category. These are the questions a Wage and Hour Division investigator will ask during an audit.
On-Call Time (All Facility Types)
- Do you have a written on-call policy defining response time requirements, geographic restrictions, and frequency expectations?
- Is on-call-on-premises time tracked separately from home on-call time?
- Is compensable on-call time (on-premises standby) counted as hours worked and included in weekly overtime calculations?
- Is the on-call stipend (if any) included in the regular rate of pay for weeks where it is paid alongside overtime?
- Have you documented the analysis of whether home on-call restrictions are sufficient to make the time compensable?
Callback Pay (All Facility Types)
- Are callback hours counted as hours worked in the same workweek as the employee’s regular hours (not tracked separately)?
- Does travel time from home to the facility for an emergency callback count as hours worked?
- Is callback pay included in the regular rate before overtime is calculated?
- If a minimum hours guarantee applies (by policy or CBA), is it applied automatically for all callback situations?
- Are callback hours visible in the employee’s total hours for the workweek before payroll is finalized?
Sleep Time (Nursing Homes and Home Health Agencies)
- Is the sleep time exclusion applied only to shifts of 24 hours or more?
- Do you have written or clearly documented implied agreements with employees for sleep time exclusion?
- Can you document that adequate sleeping facilities are provided at each location where the exclusion is claimed?
- Do you have a process for tracking whether a sleep period was interrupted and by how much?
- When sleep interruptions prevent 5 consecutive hours of rest, does the system count the entire sleep period as hours worked?
- Is the sleep time exclusion capped at 8 hours even when employees sleep longer?
- Are sleep interruptions tracked as separate compensable time entries?
Hospitals (Additional Items)
- Are charge nurse differentials and shift differentials included in the regular rate for weeks with overtime?
- Is time spent in mandatory training sessions (required by the facility outside normal hours) counted as hours worked?
- Are employees who stay past their shift to complete charting or hand off patients paid for that time?
- Is inter-facility travel time (when nurses cover multiple campuses) counted as hours worked?
- Are automated meal break deductions audited to ensure employees are actually receiving full, uninterrupted breaks?
Home Health Agencies (Additional Items)
- For live-in or 24-hour aides, is the sleep time exclusion applied only when all three FLSA conditions are met?
- Are home-to-first-patient and last-patient-to-home travel times correctly classified (generally not compensable)?
- Is patient-to-patient travel time during the workday counted as hours worked?
- Are home health aides who report frequent sleep interruptions flagged for a review of the sleep time exclusion?
- Does your payroll system handle joint employment situations (where aides work for multiple agencies) correctly for regular rate calculations?
How Netchex handles it: Netchex provides healthcare clients with earnings code audits and compliance configuration reviews as part of implementation, and the platform’s time and attendance integration means every hour tracked in the field flows directly into payroll without manual re-entry. If your current payroll system requires someone to manually reconcile on-call logs, callback sheets, and regular time entries before each payroll run, that process is a compliance risk in itself.
Healthcare Payroll Compliance Starts with the Right Configuration
On-call pay, callback pay, and sleep time rules aren’t ambiguous. The FLSA’s requirements are well-documented, and the DOL has published specific guidance for the healthcare industry. What’s ambiguous is how your payroll system is currently handling them.
An unconfigured on-call stipend code that’s excluded from the regular rate, a callback tracking system that’s not feeding overtime, a sleep time deduction that runs unconditionally regardless of whether interruptions occurred: any one of these is a systematic, recurring underpayment that compounds with every payroll run and every affected employee.
Netchex is built to handle the complexity that healthcare payroll compliance actually involves: non-exempt nurses, rotating on-call schedules, 24-hour home health shifts, multi-site operations, and shift differentials that need to land in the regular rate calculation every week without manual intervention.

Frequently Asked Questions
It depends on how restricted the employee is during the on-call period. On-call time spent on premises, or so restricted that the employee cannot use the time effectively for personal purposes, is compensable hours worked. Home on-call where the employee is free to use their time is generally not compensable, though any actual work performed when called in is always paid. Restrictions like a five-minute response window, a tight geographic radius, or very frequent calls can flip home on-call into compensable time.
Yes. Callback time is compensable from the moment the employee accepts the call, including travel time to the facility for an emergency or unscheduled return. Callback hours must be counted as hours worked in the same workweek as regular hours and included in the regular rate before overtime is calculated. Many facilities and collective bargaining agreements also add a minimum hours guarantee, often two or four hours of pay per callback.
For shifts of 24 hours or more, an employer may exclude up to 8 hours of sleep time only if three conditions are met: a written or implied agreement, adequate sleeping facilities, and the ability for the employee to usually get at least 5 consecutive hours of uninterrupted sleep. If interruptions prevent 5 consecutive hours, the entire sleep period becomes compensable. The exclusion is capped at 8 hours even when the employee sleeps longer.
Paying a flat on-call stipend that is coded as a bonus excluded from the regular rate of pay. When the underlying on-call time is compensable, that stipend must flow into the regular rate, or overtime is underpaid in any week the employee exceeds 40 hours. Two other frequent errors are tracking callback hours outside the regular workweek so they never trigger overtime, and applying the 8-hour sleep time exclusion unconditionally even when sleep was interrupted.
By configuring each earnings code with explicit, auditable flags for whether it feeds hours worked, whether it is included in the regular rate, and whether it is subject to FLSA overtime. Netchex audits existing earnings codes during implementation, applies conditional logic for sleep time exclusions, and recalculates the regular rate every workweek based on total compensation and total hours, so on-call stipends, callback pay, and shift differentials land correctly without manual reconciliation.
