Colorado On-Call Pay Rules: Sleep Time, Overtime, and Travel

Colorado on-call pay rules require your employer to pay you for on-call hours whenever the restrictions placed on you prevent routine personal activities like running errands, seeing family, or relaxing at home. The Colorado Overtime and Minimum Pay Standards Order (COMPS Order) at 7 CCR 1103-1 sets the framework, and the state minimum wage of $15.16 per hour is the floor for any compensable on-call time in 2026.¹ Whether you’re a nurse on overnight call, a maintenance tech waiting for an emergency, or an IT worker tied to a pager, the same test applies.

When On-Call Time Has to Be Paid

The COMPS Order defines “time worked” to include all time an employer suffers or permits you to work.² That sweeps in on-call hours when the employer’s rules effectively control how you spend your time. The legal shorthand is whether you’re “engaged to wait,” which is paid, or “waiting to be engaged,” which is not.³

Colorado’s Division of Labor Standards and Statistics puts it plainly: on-call time counts as time worked if the employer’s rules, or the practical realities of the arrangement, keep you from routine personal activity.⁴ If you can cook dinner, run to the store, and spend the evening with your household without meaningful disruption, the hours are probably unpaid. If you can’t, you’re working.

What Regulators and Courts Actually Look At

No single fact controls the outcome. The analysis weighs several elements together.

Response time. A tight window is one of the strongest signals that on-call time is compensable. Colorado’s guidance points to firefighters required to arrive within 20 minutes of a call; that restriction, combined with other factors, made the whole on-call shift paid. Shorter windows shrink both your geography and your choices.⁵
Geographic restrictions. Being required to stay on the premises, or inside a narrow radius, usually pushes toward paid time. If you can only travel a few miles from the worksite, you can’t do much with the hours.
Call frequency. A generous response window loses its value if calls come in every half hour. Repeated interruptions destroy your ability to use the time personally.
Trading the shift. If you can hand the duty to a coworker and truly disconnect, that freedom weighs against pay. If your employer forbids trades, it weighs in your favor.
Phone or pager use. Carrying a device generally gives you more freedom than being tied to a landline. But the device alone doesn’t decide the question. Rules that require you to answer immediately and log into a system within minutes can be as restrictive as a geographic leash.

The whole test comes back to one question. Can you effectively live your off-duty life, or has the employer’s control made that impossible? A restriction that looks minor on paper can be compensable in practice when combined with a short leash and frequent calls.

Sleep Time on 24-Hour Shifts

If your on-call shift runs 24 hours or longer, Colorado lets your employer exclude up to eight hours of sleep time from your paid hours, but only if three conditions are all met:

You and the employer have an express or implied agreement that sleep time is excluded.
The employer provides real sleeping facilities — bed, linens, and bathroom access at minimum.
You actually get at least five uninterrupted hours of sleep.

For shifts shorter than 24 hours, the rules are stricter. Sleep time is only excludable if the employer neither interrupts, nor reserves the right to interrupt, the five-to-eight-hour rest period.⁶ Sleep hours interrupted by actual work are always paid, no matter the shift length. And even when sleep hours are properly unpaid, they still count toward your total shift length for overtime purposes.

The Rate and the Overtime Triggers

Once on-call hours qualify as time worked, your employer must pay at least Colorado’s minimum wage of $15.16 per hour.¹ Some Colorado localities set a higher minimum, so check your city or county floor as well. An employer can pay a separate, lower on-call rate than your active-duty rate, but it can never dip below the applicable minimum, and any agreement to accept less is unenforceable.

Colorado’s overtime rules go beyond federal law. Your employer owes time-and-a-half whenever your hours cross any of these lines, using whichever produces the highest pay:

40 hours in a workweek
12 hours in a workday
12 consecutive hours, even if they span two calendar days

That third trigger is the one that matters most for on-call workers.⁷ A compensable on-call shift that stretches past 12 consecutive hours hits overtime even if your weekly total is well under 40. Federal law has no daily overtime rule, but Colorado’s stricter standard applies whenever it helps the worker.⁸

The overtime calculation uses your regular rate of pay, which includes all compensation for the workweek, not just your base hourly wage. On-call premiums and non-discretionary bonuses generally get folded into the regular rate before it’s multiplied by 1.5.⁹ Callback pay for genuinely unanticipated, unscheduled calls can be excluded, but only if the callback really was unplanned.

One boundary: certain salaried executive, administrative, professional, and outside sales employees are exempt from these overtime rules if they meet both a duties test and Colorado’s salary threshold, which was $55,000 in 2024 and is indexed annually.¹⁰ If you’re classified as exempt but don’t actually satisfy both parts, the exemption doesn’t stick and you’re owed on-call pay and overtime like any other covered worker.

Getting Called In: Travel Time

Your normal commute isn’t paid, even for on-call workers. But a callback is different. Under Rule 1.9.2 of the COMPS Order, travel time for the employer’s benefit, other than ordinary home-to-work travel, counts as time worked.²

Driving to your regular shift in the morning is a personal commute. Driving in at 2 a.m. because a server crashed is employer-directed travel and must be paid. The same rule applies to trips between worksites once your compensable time has started. Travel in employer-mandated transportation also becomes paid time if it significantly lengthens your commute or exposes you to greater physical risk than a normal drive.

If Your Employer Won’t Pay

Colorado’s penalties for unpaid wages are steep. If your employer doesn’t pay after receiving a written demand, the numbers climb quickly.

For non-willful violations, the penalty is double the wages owed or $1,000, whichever is greater. Combined with the unpaid wages, the total lands at roughly three times what was originally owed.
For willful violations, the penalty is triple the wages owed or $3,000, whichever is greater, putting the employer on the hook for about four times the original amount.

Timing shifts the total. Payment within 14 days of a Division order can cut penalties by 50%. Ignoring the order for more than 60 days adds another 50%, or $3,000, whichever is greater.¹¹

You have two years from the date of the violation to file, or three years if the violation was willful.¹² Don’t wait until the last month. Gathering call logs, schedules, and pay stubs takes time, and the clock runs from when the wages should have been paid.

To start a claim, complete the Labor Standards Complaint Form and submit it to the Colorado Division of Labor Standards and Statistics by mail, fax, or email with copies of your supporting documents. You can send a written demand to your employer and file with the Division at the same time. If your employer fails to pay within 14 days of receiving that written demand, you become eligible for the enhanced penalties on top of the unpaid amount.¹³ You also have the option to sue in court instead, though most workers start with the administrative complaint because it’s free and doesn’t require a lawyer.

One practical habit while you’re still on the job: keep your own log of on-call hours, call times, and response requirements. If your employer’s records are thin, yours may carry the case.
