How Many Hours is Part-Time? An Employer’s Guide to Part-Time vs. Full-Time Employment

Part-time employment can be a win-win for both employers and workers. Learn how to classify them, how they differ from full-time employees, and more.

Part-time work isn’t a lesser alternative to full-time roles — it’s a flexible solution embraced by more than 27 million Americans. 

Yet, for something so prevalent, there’s still a surprising amount of confusion about what “part-time” really means, why it’s valuable, and how to manage the role effectively. 

The conversation becomes even more relevant in the age of the gig economy and the rise of “side hustles.” The concept of employment has expanded well beyond the traditional nine-to-five (or eight-to-12) grind. 

In this guide, we’ll break down what defines part-time roles, why they’re beneficial, and how to manage this workforce effectively so your organization can stay ahead in a dynamic employment landscape. 

Key Takeaways

  • Part-time workers typically work 15-34 hours weekly, offering businesses flexible, cost-effective staffing solutions across various industries. 
  • Part-time employees are legally protected by the FLSA, ensuring minimum wage, overtime pay, and anti-discrimination safeguards despite receiving fewer benefits. 
  • Part-time work benefits both employees (work-life balance, extra income) and employers (cost savings, staffing flexibility, talent access), creating a mutually advantageous arrangement. 

What is a Part-Time Worker?  

A part-time worker is an employee who works fewer hours than a full-time employee — typically fewer than 40 hours per week — and is paid hourly.  

Part-time workers are also usually classified as "non-exempt," meaning they're eligible for overtime pay and certain other benefits (such as minimum wage and youth employment standards) under the Fair Labor Standards Act (FLSA). 

How Many Hours is Part-Time? 

Part-time work typically ranges from 15 to 34 hours per week, but that can vary based on the  industry and employer.  

For compliance purposes, the IRS defines a full-time employee as someone who averages 30 hours per week over a month. This means that even if an employee works fewer than 40 hours per week, they may still be considered full-time by IRS standards — regardless of whether their employer classifies them as “part-time.” 

What’s the Difference Between a Part-Time Worker vs. Full-Time? 

Part-time and full-time employees differ in key areas, such as hours, benefits, pay, and legal protections. While every job varies, here’s how the two classifications are typically distinguished: 

  Part-Time Full-Time
Hours per Week 15-34 hours  35-40 hours 
Benefits Limited or no benefits  Comprehensive (health coverage, paid time off, retirement plans) 
Compensation Usually hourly wage  Salary, potential bonuses 
Legal Protections Fewer employment protections, may not qualify for certain benefits  More comprehensive regulations 

The FLSA governs employee classifications in the U.S., but doesn’t provide a specific definition of "part-time" or "full-time" employment. It does, however, set minimum wage requirements, overtime pay laws, and paid leave mandates. 

Minimum Wage and Overtime Requirements 

Whether an employee works part-time or full-time, employers must pay at least the federal, state, or sometimes local minimum wage, whichever is higher. As of 2025, the federal minimum wage is $7.25 per hour.  

Regardless of part-time or full-time status, the FLSA also requires employers to pay non-exempt employees overtime pay of 1.5 times their regular rate for any hours worked over 40 hours in a workweek.

Health Coverage Requirements 

The Affordable Care Act (ACA) has specific mandates for large employers (those with 50 or more full-time equivalent (FTE) employees) to offer health insurance to full-time workers.  

According to the ACA, full-time employees are defined as those who work an average of 30 hours per week or 130 hours per month. Employers are not, therefore, required to offer health insurance to employees who work fewer than 30 hours per week. 

Benefits & Perks  

While federal law doesn’t require employers to offer paid leave, retirement benefits, or holiday pay to part-time workers, employers may voluntarily provide these benefits as part of their recruitment and retention strategy. 

Payroll Taxes and Withholding 

Part-time employees are subject to the same payroll tax rules as full-time employees. Employers must withhold Social Security, Medicare, and federal income taxes from part-time workers' paychecks. 

Anti-Discrimination Laws & Equal Treatment 

Discrimination based on age, race, gender, disability, or other protected statuses is illegal for all employees, regardless of hours worked. Therefore, part-time employees are entitled to the same anti-discrimination protections as full-time employees, and employers must still comply with anti-discrimination laws enforced by the Equal Employment Opportunity Commission (EEOC).

What are the Benefits of Part-Time Work? 

When implemented strategically, part-time positions can be a win-win for both workers and employers. 

Employee Benefits 

  • Mental and physical wellness: Part-time work has been associated with a reduction in sick days as fewer working hours allow employees more time for self-care and mental well-being. This, in turn, leads to less burnout.   
  • Work-life balance: Part-time roles allow employees to set work hours around personal responsibilities, such as caregiving or education. Employees can pursue degrees, certifications, or passion projects while earning an income. 
  • Additional income: Part-time employees can take on multiple part-time roles to diversify their income sources. 
  • Career development: Part-time jobs sometimes lead to full-time positions, allowing employees to "test the waters" before committing to a role. 

Employer Benefits 

  • Cost savings: Workforce management is more cost-effective with part-time employees since they’re only paid for the hours they work.  Moreover, employers typically aren’t required to provide health insurance, retirement plans, or paid leave to employees who work less than 30 hours per week. 
  • Increased staffing: Employers can schedule part-time workers to support full-time staff during high-traffic periods or seasons. 
  • Access to a broader talent pool: Part-time roles appeal to skilled professionals with complicated schedules or commitments (e.g., parents, full-time students, artists, performers, etc.) who want (or need) more flexible lifestyles.  
  • Potential tax benefits: Some part-time employees may qualify your organization for a Work Opportunity Tax Credit (WOTC). WOTC applies to specific groups, including those who might be more inclined to work part-time jobs, such as students.

When to Hire Part-time vs. Full-Time  

Not sure whether to hire part-time or full-time? Here are some key considerations to help you decide. 

When To Hire Part-Time Workers 

Experience fluctuating demand: If demand for labor fluctuates throughout the year (e.g., holidays or busy seasons), part-time workers can provide on-demand support. This is ideal for retailers, hospitality, food service, and tourism-related businesses. 

Want to cut costs: Part-time workers can fill the gaps for growing businesses that aren’t ready for full-time employee costs (i.e., wages and benefits). This is ideal for startups, small businesses, and companies with limited cash flow. 

You Need Specialization (on a Limited Basis): Sometimes, you don’t need a full-time expert — just someone with specific skills for a few hours a week. Part-time hiring is great for consultants, designers, or IT specialists who can contribute without the commitment of a full-time salary.

When to Hire Full-time Employees 

  • Long-term stability: If a role requires consistent, ongoing work and has little variability in demand, hire a full-time employee. Full-time staff are more likely to commit to the company, reducing turnover and ensuring operational continuity. 
  • Specialized talent: Some roles require specialized skills that are difficult to find on a part-time basis (e.g., software developers, engineers, HR professionals, and legal advisors). 
  • Team Cohesion: Full-time employees are likelier to engage in company culture, participate in team-building activities, and develop long-term relationships with coworkers.  

FAQs About Employing Part-time Workers  

Do Part-Time Workers Get Holiday Pay?  

Federal labor laws, like the FLSA, don’t require employers to offer holiday pay (i.e., paid time off (PTO) for holidays) to part-time employees in the U.S. 

Can Part-Time Workers Earn Paid Time Off?  

Yes, but it depends on company policy, local labor laws, and the hours worked: 

  • Federal law: U.S. federal law doesn’t require PTO for part- or full-time employees. 
  • Company policy: Many employers offer prorated PTO for part-time workers. For instance, if a full-time employee earns 80 hours of PTO annually, a part-time worker working 20 hours per week may receive 40 hours of PTO. 
  • State/local laws: Certain states (like California, New York, and Washington) require employers to provide paid sick leave to all employees, including part-time workers. 

Are Part-Time Workers Considered Contractors?  

No, part-time employees and independent contractors are different. While contractors may work part-time for an employer, they’re usually not hired employees. Instead, they typically work for themselves while managing their own taxes, benefits, and assignments.  

Part-time workers, on the other hand, are usually hired employees who often receive an offer letter or written agreement from their employer outlining various expectations (e.g., hours, pay, working conditions, etc.) 

Do Part-Time Workers Get Sick Pay?  

Part-time employees can receive sick pay, but it depends on state laws and the employer’s leave policy. For example, states like California, New York, Arizona, and Washington require all employees (including part-time) to accrue paid sick leave, while others don’t.  

Do Part-Time Workers Get Overtime?  

Yes, under federal law, part-time workers are entitled to overtime pay if they work more than 40 hours in a workweek. 

FLSA requirements mandate all non-exempt employees (both part-time and full-time) to receive overtime pay at 1.5x their hourly rate for any hours worked over 40 a week. 

How Long Is a Part-Time Shift? 

A part-time shift typically ranges from two to eight hours, with most shifts averaging between four to six hours, depending on the industry, job role, and specific employer needs.
