Compensable Work Time Under Portal-to-Portal Act

Few employment law questions sound simple and then immediately put on roller skates quite like this one: “Do employees have to be paid for that?” The “that” might be walking from a parking lot, putting on protective gear, booting up a computer, waiting for equipment, attending a meeting, traveling to a customer site, or answering a manager’s “quick” text after clocking out. Spoiler: “quick” is often where payroll trouble begins.

Compensable work time under the Portal-to-Portal Act is one of the most important topics in wage and hour compliance because it decides which minutes count as paid work under the Fair Labor Standards Act, commonly called the FLSA. Those minutes can affect minimum wage, overtime, payroll records, employee morale, lawsuits, and the special workplace sport known as “who moved the time clock?”

The Portal-to-Portal Act does not replace the FLSA. Instead, it narrows and clarifies certain categories of time that may be excluded from paid working time, especially ordinary commuting, walking, riding, traveling to and from the actual place of principal work, and activities that are preliminary or postliminary to the employee’s main job duties. But there is a major catch: if the activity is integral and indispensable to the employee’s principal work, it may still be compensable.

What Is the Portal-to-Portal Act?

The Portal-to-Portal Act of 1947 amended the FLSA after courts had interpreted “hours worked” broadly. Congress wanted to clarify when employers must pay for work-related time before and after the main workday. The law generally says employers do not have to pay for time spent traveling to and from the actual place where the employee performs principal activities, or for activities that are preliminary or postliminary to those principal activities.

That sounds employer-friendly, but it is not a free pass to erase every pre-shift or post-shift task. The law still protects time spent performing the employee’s principal activities, plus tasks that are so closely connected to those activities that the job cannot be properly performed without them.

The Core Rule: Principal Activities Are Paid

A principal activity is the work the employee is employed to perform. For a cashier, that may include operating the register and assisting customers. For a factory worker, it may include running machinery. For a call-center employee, it may include using required software to handle customer calls. For a nurse, it may include patient care and required clinical preparation.

The key phrase in Portal-to-Portal Act analysis is “integral and indispensable.” An activity is more likely to be compensable when it is an intrinsic part of the job and necessary for the employee to perform the principal work safely, effectively, or legally. In plain English: if the task is not just helpful but required for the real job to happen, payroll should pay attention.

Examples of Likely Compensable Activities

Some common examples of compensable work time may include:

• Putting on and taking off required protective gear that is necessary for hazardous work.
• Cleaning, sharpening, calibrating, or preparing tools required for production.
• Starting up required computer systems when the system is essential to the job.
• Traveling between job sites after the workday has begun.
• Waiting time when the employee is engaged to wait and not free to use the time personally.
• Mandatory meetings, required training, or job-related instruction.
• Short rest breaks, usually 5 to 20 minutes, when provided by the employer.

Examples of Often Non-Compensable Activities

On the other side, some activities are often not compensable under federal law:

• Ordinary home-to-work commuting.
• Walking from a parking lot to the workplace before any principal activity begins.
• Waiting for or going through ordinary security screenings when the screening is not integral to the employee’s actual job duties.
• Voluntary training outside regular work hours that is not job-related and involves no productive work.
• Bona fide meal breaks when the employee is fully relieved from duty.

The word “often” matters. Wage and hour law is allergic to lazy assumptions. A few changed facts can move time from unpaid to paid faster than an employee can say, “But my manager told me to do it.”

Preliminary and Postliminary Activities Explained

Preliminary activities happen before the employee’s principal work begins. Postliminary activities happen after the principal work ends. Brushing snow off your own car before driving to work is not part of your job. But preparing specialized equipment required by the employer may be different.

For example, a warehouse employee who waits in a security line after work may not be owed pay if the security check is for theft prevention and is not intrinsic to retrieving and packaging products. However, a food processing employee who must put on required sanitary and protective gear before entering the production floor may have a stronger claim that the time is compensable because the gear is necessary to safely and legally perform the production work.

The Continuous Workday Rule

The continuous workday rule is where the Portal-to-Portal Act gets spicy. Once an employee performs the first principal activity of the day, the workday generally continues until the last principal activity is completed. That means activities occurring between those points may be compensable, even if similar activities before the first principal activity or after the last principal activity would not be.

Consider a manufacturing employee who must put on required protective gear in a locker room before working on the production line. If donning that gear is a principal activity because it is integral and indispensable, then walking from the locker room to the production floor may also become part of the compensable workday. The walk is no longer just a casual stroll through the workplace; legally, it may be inside the paid workday.

Travel Time Under the Portal-to-Portal Act

Travel time is one of the most misunderstood areas of compensable work time. Ordinary commuting from home to work and back is generally not paid time. This remains true even if the commute is long, boring, traffic-filled, or emotionally improved only by coffee and a podcast.

But travel during the workday is different. If an employee reports to one job site and then must travel to another site for the employer’s benefit, that travel time is generally compensable. A technician who drives from the shop to customer locations after starting the day is working while traveling. A caregiver who moves from one client’s home to another during the day may also be working during that travel time.

Special One-Day Assignments

If an employee who normally works in one city is sent to another city for a special one-day assignment and returns the same day, the travel time may be compensable, except the employer may usually subtract the time the employee would normally spend commuting to the regular worksite.

Overnight Travel

Overnight travel has its own rules. Travel away from home that cuts across the employee’s regular working hours is generally treated as work time, even if the travel occurs on a nonworking day. For example, if an employee normally works 9 a.m. to 5 p.m. Monday through Friday and travels from 10 a.m. to 2 p.m. on Sunday for a work assignment, that Sunday travel may count as hours worked because it overlaps the employee’s normal working hours.

Donning and Doffing: The Famous Gear Problem

“Donning and doffing” is the legal phrase for putting on and taking off gear, uniforms, or equipment. It sounds like something from a medieval laundry guild, but it is a major wage and hour issue.

If employees merely change into ordinary clothes or a basic uniform for convenience, the time may not be compensable under federal law, especially when a valid collective bargaining agreement excludes certain clothes-changing or washing time. But if employees must put on specialized protective equipment required by the nature of the work, and the gear is necessary to perform the job safely, the time may be compensable.

Examples include protective gear for meat processing, chemical work, medical environments, or manufacturing settings where safety equipment is not optional. The more the gear protects against workplace-specific hazards, the stronger the argument that putting it on and taking it off is integral and indispensable.

Security Screenings and Exit Checks

Security screenings are not automatically compensable. In a major Supreme Court case, warehouse employees argued they should be paid for time spent waiting for and passing through anti-theft screenings after their shifts. The Court held that the screenings were not compensable because they were not the principal activity the employees were hired to perform and were not integral and indispensable to retrieving and packaging warehouse products.

That does not mean every screening in every workplace is unpaid. The analysis depends on whether the screening is intrinsic to the principal work. But general loss-prevention checks, bag checks, and exit screenings are often treated as non-compensable under federal law unless state law, a contract, or unusual facts point the other way.

Computer Startup, Login Time, and Remote Work

Modern work has given the Portal-to-Portal Act a new villain: the spinning login wheel. For employees who cannot perform their jobs until they boot up a computer, launch required software, authenticate into secure systems, and become available in the employer’s platform, that time may be compensable if it is integral and indispensable to the job.

For example, a call-center employee required to be ready to take calls at exactly 8:00 a.m. may need to start the computer and log into multiple systems before that time. If the employer requires those steps and the employee cannot perform the principal job without them, treating the startup time as unpaid can create risk.

Remote work adds another layer. The home may be the location, but the legal question is still about control, requirement, and benefit. If a nonexempt employee performs required work before clocking in, after clocking out, or during unpaid breaks, the time may count as hours worked even if the employee is sitting at a kitchen table next to a suspiciously judgmental cat.

Waiting Time and On-Call Time

Waiting time is compensable when employees are “engaged to wait.” This means the employee is not truly free to use the time for personal purposes. A receptionist waiting for the phone to ring, a firefighter waiting for an emergency call, or a machine operator waiting for equipment to reset may still be working.

By contrast, time may be unpaid when an employee is “waiting to be engaged.” If the employee is completely relieved from duty, told when to return, and can use the time effectively for personal purposes, the time may not count as hours worked.

On-call time follows a similar logic. If an employee can remain at home, move around freely, and respond only occasionally, on-call time may not be compensable. But if restrictions are so tight that the employee cannot effectively use the time personally, the time may become compensable.

Training, Meetings, and Lectures

Training time is generally compensable unless all four of these conditions are met: attendance is outside regular working hours, attendance is voluntary, the training is not directly related to the employee’s job, and the employee performs no productive work during the training.

If the boss says, “Everyone must attend,” the word “voluntary” has left the building. If the training teaches employees how to do their current job better, it is usually job-related. If employees answer emails, help customers, prepare reports, or perform work during the session, the time is generally compensable.

Breaks, Meal Periods, and the Myth of the Magic Lunch

Short rest breaks, usually lasting from 5 to 20 minutes, are generally counted as hours worked. They are part of the workday and must be included when calculating overtime. Employers do not get to say, “That break was unpaid because you enjoyed it too much.”

Meal periods are different. A bona fide meal period, commonly 30 minutes or more, is generally not compensable if the employee is completely relieved from duty. But if an employee must answer phones, monitor equipment, watch a front desk, respond to messages, or stay ready to jump back into work, the meal period may be compensable.

Why Accurate Timekeeping Matters

Compensable work time is not just a payroll detail. It affects overtime calculations, recordkeeping, compliance costs, employee trust, and litigation exposure. A few unpaid minutes per day can become hundreds of unpaid hours across a workforce. Multiply that by overtime rates, liquidated damages, attorney fees, and several years of records, and suddenly the “tiny time issue” is wearing a very expensive hat.

Employers should train managers not to encourage off-the-clock work, review pre-shift and post-shift practices, audit travel policies, and make sure timekeeping systems capture all required work. Employees should keep accurate records, report unpaid work time through proper channels, and understand that job titles do not decide compensability; actual duties and employer requirements do.

Practical Examples of Compensable Work Time

Example 1: The Warehouse Exit Check

A warehouse worker spends 15 minutes after each shift waiting for a general anti-theft screening. If the screening is not intrinsic to the worker’s job of picking and packing orders, the time may be non-compensable under federal law.

Example 2: The Factory Protective Gear

A factory employee must put on specialized protective gear before working around hazardous materials. Because the gear is required for safe performance of the principal work, the donning and doffing time may be compensable.

Example 3: The Traveling Technician

A technician reports to the company office at 8:00 a.m., receives assignments, loads tools, and then drives to customer sites. The drive from the office to customer sites is generally part of the compensable workday.

Example 4: The Required Online Training

A nonexempt employee is told to complete a required cybersecurity training module at home after hours. Because the training is required and job-related, the time should generally be paid.

Common Mistakes Employers Make

One common mistake is assuming that anything before clock-in or after clock-out is unpaid. That is wrong. If the employer knows or has reason to know that work is being performed, the time may be compensable.

Another mistake is treating small amounts of time as too minor to matter. Small daily tasks can add up quickly. Five unpaid minutes per day equals more than 20 unpaid hours per year for one employee. Across 100 employees, that is not a rounding error; it is a payroll gremlin with a calculator.

A third mistake is copying a policy from another company without considering the actual workplace. Portal-to-Portal Act analysis is highly fact-specific. A policy that works for a retail store may fail in a laboratory, hospital, call center, manufacturing plant, or construction setting.

Employee Experience: What This Issue Looks Like in Real Life

In real workplaces, compensable time issues rarely arrive with a dramatic soundtrack. They usually begin as small habits. A team starts logging into software before the shift because the system takes seven minutes to load. A supervisor asks employees to “just check messages” before clocking in. A crew gathers at a yard, waits for tools, and then rides to the jobsite. A nurse gives handoff information during an unpaid meal break. Nobody calls it a wage and hour problem at first. They call it “how we’ve always done it.” That phrase is famous for causing compliance headaches.

One practical experience many employees share is confusion about preparation time. Workers often assume that if a task is required, it must be paid. Employers sometimes assume that if a task occurs before the official shift, it is unpaid. The legal answer sits between those two assumptions. Required is important, but the deeper question is whether the task is part of the principal work or integral and indispensable to it. Putting on a company polo may be different from putting on required protective equipment. Walking from a parking lot may be different from walking to the production floor after completing a required principal activity.

Another common experience involves technology. In office, call-center, logistics, and remote-work environments, employees may spend unpaid minutes opening programs, connecting to VPNs, reading required updates, or setting status indicators. When those steps are necessary before the employee can perform the job, they deserve careful review. A company may think of login time as “setup,” while employees experience it as the first task of the day. When the system is slow, the issue becomes more obvious. Nobody wants to donate unpaid time to a frozen screen.

Travel creates similar friction. Employees may understand that commuting is unpaid, but they become frustrated when travel rules are applied too broadly. Driving from home to the regular workplace is usually not paid. Driving from the first jobsite to the second jobsite during the workday is usually different. Special one-day assignments, overnight travel, and mandatory reporting locations can create gray areas. Clear written policies help, but policies must match actual practice. Payroll cannot be managed with wishful thinking and a mileage chart from 2009.

The best workplace experience comes from clarity. Employers should explain what must be recorded, when the workday begins, how to report pre-shift or post-shift tasks, and who can approve unusual time. Employees should not have to guess whether required work counts. Managers should avoid phrases like “do it off the clock,” which is basically wage-and-hour confetti thrown directly into a courtroom fan.

For employees, the practical lesson is to track time honestly and raise concerns professionally. For employers, the lesson is to audit reality, not just policy. Watch what employees actually do before and after shifts. Ask whether the task benefits the employer, whether it is required, whether it is tied to principal work, and whether employees are free to skip it. The Portal-to-Portal Act rewards careful analysis, not assumptions. In daily workplace life, the safest rule is simple: when required tasks are necessary for the real job to happen, take the time seriously.

Conclusion

Compensable work time under the Portal-to-Portal Act depends on the difference between ordinary preliminary or postliminary activities and tasks that are integral and indispensable to an employee’s principal work. Ordinary commuting is usually unpaid. General security checks may be unpaid. But required protective gear, essential computer startup, mandatory training, workday travel, restricted waiting time, and interrupted meal periods may be compensable depending on the facts.

For employers, the smartest approach is to build policies around actual work, not idealized schedules. For employees, the smartest approach is to understand the rules, keep accurate records, and speak up when required work is not being counted. Time may be invisible, but under wage and hour law, invisible minutes can still have a very visible price tag.
