Part-Time vs. Full-Time Jobs: What's the Difference?

Featured Image

The difference between part-time and full-time employees is the number of hours they work. While employers have some wiggle room, there are specific labor laws that determine how businesses classify employees.

Understanding how part-time versus full-time status affects employees and your organization is part of the delicate balance between what you can ask of employees and what they’re willing to give you. Many factors influence that balancing act, like your compensation strategy, workplace culture, or rewards and recognition strategies.

Achieving this balance is the key to a workplace with satisfied employees doing their best for an organization they appreciate. Taking advantage of employees by fiddling with their status doesn’t tip the balance in the employer’s favor. Instead, it tends to upend good jobs and create unnecessary turnover.

What's the Difference Between Part-Time and Full-Time?

What Is Considered Part-Time?

In the U.S., the Fair Labor Standards Act establishes guidelines that affect all employees. The law doesn't define part- or full-time employment. Instead, employers determine workers' employment status—and the law applies equally to everyone.

Career experts estimate that most part-time employees work 15 to 29 hours per week. For example, Amazon employees are considered part-time if they work 20 to 29 hours per week under the company's current policies.

These examples align with categories used by the Bureau of Labor Statistics:

Within federal agencies, the U.S. Office of Personnel Management defines part-time work as less than 40 hours per week. Workers who participate in job sharing can work a maximum of 32 hours per week.

Part-Time Employees: Pros and Cons

Pros for Employees

Pros for Employers

  • Better work-life balance: Working shorter hours and fewer days a week may help employees have more energy overall.
  • Easier to gain experience: Part-time employees can try new jobs without needing a lot of prior experience, and they can look for the right company culture without committing to a full-time contract.
  • More affordable: You don’t have to pay for benefits (unless you’re an ALE) or overtime, and if you’re on a tight budget, you can hire qualified professionals part-time without footing the full-time bill.
  • More workplace flexibility: Part-time workers can bridge personnel gaps quickly and efficiently.

Cons for Employees

Cons for Employers

  • Fewer benefits: While some companies offer benefits for part-timers, it’s not as common as for full-time positions.
  • Less job security: They may be seen as more expendable since employers don’t have to make as big an investment in them.
  • Schedule stress: Part-time workers are often kept “on call,” meaning they need to remain available to work but aren’t guaranteed hours.
  • Lower engagement: Part-time employees don’t spend as much time at work, so they may not contribute as much to company culture or be motivated to achieve company goals.
  • Less dependability: Again, because there’s less involvement and commitment on both sides, part-timers may feel less beholden to their employer’s needs.
  • Managerial stress: Part-time schedules means more workers for managers to supervise and train, and managers likely have to frequently repeat employee training and other communication.

Full-Time Employees: Pros and Cons

Pros for Employees

Pros for Employers

  • Better benefits: There’s no law requiring businesses to give full-time employees benefits like health insurance (unless they’re an ALE) and paid time off, but these tend to be more common with full-time positions.
  • Higher take-home pay: Full-time employees, especially salaried positions, work more hours, so they earn more money.
  • More responsibility: Since they spend more time at work, full-time employees can handle more broad responsibilities like management or inventory tracking.
  • Increased loyalty: The additional benefits attached to full-time employment tend to create more engagement and dedication.

Cons for Employees

Cons for Employers

  • Risk of burnout: More hours, more responsibility, and higher expectations can lead full-timers to feeling overwhelmed, taken advantage of, or just plain tired of their job.
  • Less flexibility: They might not feel like they can maintain a good work-life balance because they work more hours.
  • Risk of employee burnout: We’re saying it twice because it cuts both ways—for employers, pushing full-timers too hard can kill the golden goose and make them less productive or engaged.
  • Higher payroll and benefit costs: Because of overtime rules and ACA requirements, you may need to pay them more for their work and have to offer health insurance.

Federal Laws That Impact Part Time vs. Full Time Work

The Affordable Care Act

Under the Affordable Care Act (ACA), the Internal Revenue Service (IRS) considers someone full time if they work an average of at least 30 hours a week or 130 hours a month. However, the IRS and ACA don’t regulate when employees put in their hours, so that 30 hour cut-off still leaves employers a fair amount of flexibility when determining part-time versus full-time hours.

For example, a part-time employee at one business could work a morning shift every weekday, but a different business might have their part-time employees working longer hours on just a few days a week.

The ACA also requires applicable large employers (ALEs) to offer affordable, minimum essential healthcare coverage (or pay a penalty) and report additional information to the IRS. An employer is considered an ALE if they had at least 50 full-time or full-time equivalent employees (FTEs) during the previous year. In other words, even if you don’t have 50 full-time employees, you might still be considered an ALE if all your employees’ work hours add up to the equivalent of 50 full-time workers’ hours.

Here’s how to calculate your number of FTEs:

Again, if you have at least 50 FTEs, then you’ll be on the hook for either providing health insurance that meets the ACA minimum requirements or making an employer shared responsibility payment. If you have under 50 FTEs, you’re considered a small business, which means you don’t have to offer health insurance (but you still can if you want to).

Fair Labor Standards Act (FLSA)

The FLSA regulates several aspects of employment, including child labor, recordkeeping, minimum wage, and—most importantly for our discussion—overtime.

According to the FLSA, you’ll need to pay employees overtime, or time and half pay, if they meet the following criteria:

To clarify, exempt employees, though likely working full-time as salaried employees, are not eligible for overtime compensation if they’re paid more than $468 per week on a salaried basis and perform exempt duties.

What does that mean for your full-time employees? Most likely, if they’re hourly workers, it means you’ll need to pay them overtime when they work more than 40 hours a week. If they’re salaried (exempt) employees, you can ask them to work more than 40 hours a week without paying them overtime.

Case Study: Why Does the Part Time vs. Full Time Definition Matter?

Note: We’ve changed the names of all involved.

Here’s a cautionary tale from one of our colleagues, John, on how not to squander talented employees by mishandling their part-time versus full-time status.

In a previous role as a retail manager at a small operation, John hired a friend—we’ll call her Andrea—as a part-time sales associate at the store he managed. Andrea ended up performing so well in her part-time role that John promoted her to assistant manager, a position that would move her to working full-time.

Now that sounds like a hiring dream come true, no? Everyone involved took advantage of all the benefits of part-time work:

The business owner simply didn’t invest in or value his full-time employees. Instead, he demanded they work long hours for barely competitive wages, offered meager benefits, and provided no development path for talented workers.

But this potentially dream scenario was in fact a worst case scenario, especially for Andrea. “She burned out,” John explains. “It was more than she’d wanted, and we were asking too much of her. What started as a fun way to make some money a few days a week became a burden she was only willing to bear out of her friendship with me.”

More commitment from Andrea meant more involvement in the business’s operation and culture, which had major flaws. The business owner simply didn’t invest in or value his full-time employees. Instead, he demanded they work long hours for barely competitive wages, offered meager benefits, and provided no development path for talented workers like Andrea.

John feels that things might have been very different but for the promotion. He points out that “Andrea was a highly educated, hard-working, and smart woman in a dead-end job. She was a great sales associate and a great assistant manager, but she was also smart enough to know that she was worth more.” And so she left the business entirely.

With a better culture, better compensation, and more career development opportunities—like a path to a buyer or regional manager role, for example—Andrea might have been happy as a full-time employee. Or if she had stayed part-time, she might have continued being a super sales associate, energized and productive because she didn’t see it as a burden. “But instead, we lost a great employee,” says John.

Part-Time or Full-Time? Either Way, Do the Right Thing

As with many aspects of HR, there are lots of rules and regulations to consider when looking at the difference between part-time and full-time employees. And while those are certainly important from a budget and compliance perspective, John’s experience with Andrea highlights that employers shouldn’t lose sight of the employee experience as they weigh the pros and cons of different employee schedules.

Whether your employees are part-time or full-time, you need to help them feel valued, invested, and successful if you want your business to succeed.
