Picture two employees commencing their workday. One arrives punctually, prepares for a full eight-hour day, and immerses themselves in tasks until the late afternoon. The other arrives slightly later, dedicates themselves to work for five hours, and then departs, enjoying their afternoon for personal activities.
The latter scenario illustrates part-time work—an increasingly prevalent arrangement as both employers and employees seek enhanced flexibility. The Bureau of Labor Statistics indicates that over 27 million U.S. workers are engaged in part-time employment.
However, the question remains: what precisely constitutes “part-time”? Is it simply working fewer than 40 hours per week? Or are there additional factors that define this employment category?
This guide aims to clarify part-time work, examining the typical hours of part-time employees, exploring the advantages and disadvantages for employers, and addressing crucial aspects such as benefits and costs. By the end, you will possess a comprehensive understanding of how to classify and manage part-time employees effectively.
Understanding the Definition of a Part-Time Job
Before delving into schedules and hours, it’s essential to establish a clear definition. To define part-time work accurately, we must differentiate it from a full-time job.
A part-time job is a form of employment where an employee works fewer hours per week compared to what the company designates as full-time.
The definition of “full-time” can differ across organizations and industries. Some companies consider 35 hours per week to constitute a full-time schedule, while others set the standard at 37.5 or 40 hours. Notably, the Fair Labor Standards Act (FLSA), which governs numerous employment laws, does not legally define full-time or part-time hours.
Consequently, in the absence of a universal legal definition, each employer is responsible for determining what constitutes a part-time role within their organization. This is commonly achieved by establishing a weekly hours threshold, below which a position is categorized as part-time.
For instance, an employer might stipulate the following:
- Employees working less than 30 hours per week are classified as part-time.
- Employees working 30-39 hours per week are considered full-time.
- Employees working 40 hours or more are full-time and eligible for overtime compensation.
Part-time arrangements are most common in sectors like retail, hospitality, and healthcare, where labor demands often fluctuate. However, they are increasingly being adopted in professional fields as well, as companies strive to attract talent by accommodating diverse scheduling needs.
Decoding Part-Time Hours: How Many Hours Is Part Time Weekly?
Considering that full-time is often defined as approximately 40 hours per week, how many hours do part-time employees typically work? The answer varies, but here are some prevalent arrangements to understand How Many Hours Is Part Time:
- 30-34 hours per week: While some employers consider this range as part-time, it’s worth noting that working 30 or more hours per week often meets the threshold for benefits eligibility under various regulations. This schedule might entail working 6-7 hour days or having an additional day off each week.
- 20-29 hours per week: This is a standard schedule for numerous part-time jobs, equating to roughly 4-6 hours per day over a five-day workweek. Employees in this range often work half-days or shorter shifts.
- Under 20 hours per week: Certain part-time positions, such as those suitable for students or semi-retired individuals, may only require 10-15 hours of work per week. This could involve a single full shift or a couple of half-days.
- Variable hours: Some part-time employees, particularly in retail or gig economy roles, may not have a fixed schedule. Their hours can fluctuate weekly based on the employer’s operational requirements.

Part-time work frequently offers enhanced work-life balance compared to full-time positions, making it appealing to individuals managing multiple responsibilities or seeking schedule flexibility. For salaried part-time workers, the focus shifts from clocked hours to reduced overall responsibilities and workload. For instance, a part-time lawyer might still work 35 hours a week but manage fewer cases than their full-time counterparts. The common thread is that part-time work entails significantly fewer hours than the conventional 40-hour workweek. However, within this broad definition, there is considerable scope for diverse arrangements.
Part-Time vs. Full-Time Workers: Key Classification Differences
While the FLSA does not offer specific definitions for part-time and full-time employment, other regulations, such as the Affordable Care Act (ACA), do. This discrepancy can create complexity for employers, particularly Applicable Large Employers (ALEs).
Under the ACA, ALEs—companies with 50 or more full-time employees or full-time equivalents—have specific obligations. The ACA defines full-time as working 30 hours or more per week on average, or 130 hours per month. ALEs are mandated to offer affordable, minimum essential health coverage to at least 95% of their full-time employees or face potential penalties.
Given the variability in definitions and requirements, it is crucial for employers to clearly define and document their organization’s criteria for part-time work. Misclassifying employees as part-time when they are actually working full-time hours can result in significant legal and financial liabilities.
Furthermore, the FLSA mandates that employers pay nonexempt employees overtime rates for any hours worked exceeding 40 in a week, irrespective of their part-time or full-time status. Therefore, even if an employee is considered part-time, if they work 45 hours in a particular week, overtime pay is likely required.
Beyond ACA compliance, benefits eligibility can also be affected by classification. Many company-specific benefits policies, state laws, and other regulations may have their own thresholds for part-time and full-time status, further emphasizing the need for clear and well-documented policies.
To prevent confusion or compliance errors, it is advisable to explicitly outline the part-time/full-time distinction in your employee handbook and hiring contracts. Clearly state the number of weekly hours that constitute part-time and full-time work, and clarify the implications for pay, overtime, and benefits. By establishing and communicating clear thresholds, you ensure that all parties are aligned regarding employment status and entitlements.
Benefits for Part-Time Employees: What to Know
A significant distinction between part-time and full-time roles often lies in eligibility for company-provided benefits, such as health insurance, retirement plans, and paid leave. Do part-time employees receive any of these benefits?
As with many aspects of part-time work, the answer is conditional. There is no universal legal requirement for employers to provide benefits to part-time employees. Federal law only mandates offering health coverage to those working 30 or more hours per week, and there is no obligation to provide other types of benefits.
However, some state and local laws do impose benefit requirements for part-time workers. For example, certain jurisdictions may mandate paid sick leave for all employees, regardless of their part-time or full-time status.
Beyond legal obligations, some employers choose to extend limited benefits to part-time employees as a strategy to attract and retain talent. They might offer prorated vacation days or permit part-time employees working over 20 hours per week to enroll in the company health plan.
Ultimately, the benefits accessible to part-time employees are determined by each employer, based on their legal obligations, industry standards, and talent acquisition goals. This is a crucial factor to consider when contemplating part-time hiring.
Advantages of Hiring Part-Time Employees
Considering talent needs, let’s explore the primary reasons why an employer might opt for part-time hiring. While full-time employees are often the default choice, there are several compelling advantages to expanding your part-time workforce:
Cost Efficiency
Hiring part-time employees for roles that do not necessitate 40 hours per week enables you to align staffing precisely with your business demands. This approach ensures that you are only paying for the hours of work actually needed, optimizing your budget and avoiding unnecessary expenses linked to full-time positions for part-time workloads.
Scheduling Versatility
Part-time employees empower you to create a more flexible and responsive workforce. You can deploy them to cover peak hours, seasonal increases in demand, or specific days without committing to a full-time schedule.
Real-world Example: A café might employ several part-time staff members to manage the morning rush and then reduce staffing as business slows down in the afternoon. Alternatively, a tax firm might engage part-time CPAs during the busy tax season in the spring. This flexibility is also attractive to workers who need to balance their employment with other commitments, such as parenting, caregiving, or education.
Trial Period Opportunities
Uncertain if a candidate is the right fit for a full-time role? A part-time arrangement can serve as an extended evaluation period. You can assess their skills, work ethic, and cultural alignment in a less demanding context before deciding whether to offer them a full-time position. This is an effective method to tap into new talent pools; initiating them in a part-time capacity allows you to test their suitability while they become familiar with the company.
Filling Specialized Skill Gaps
Occasionally, you might have a short-term project that requires specialized skills that your full-time team lacks. Instead of making a full-time hire, you can bring in an experienced part-time consultant to complete the project without disrupting your core team. Fractional CFOs are a prime example of this. Many small businesses require strategic financial guidance but cannot afford a full-time CFO. Hiring one on a part-time basis allows them to access high-level expertise as needed.

Disadvantages of Hiring Part-Time Employees
Naturally, part-time hiring is not without potential downsides. There are potential drawbacks to consider:
Reduced Availability
While the scheduling flexibility of part-time employees is advantageous, it can also lead to coverage gaps. If a role necessitates daily consistency, such as a receptionist or customer service representative, relying solely on part-time staff can result in understaffing. You might need to hire multiple part-time employees to cover the hours that a single full-time employee could, increasing coordination and management overhead. Furthermore, because part-time employees often have other commitments outside of work, they may have less flexibility to take on extra shifts when required.
Increased Turnover Rates
For some employees, part-time roles are a temporary measure on the path to full-time employment, either within your company or elsewhere. This can lead to higher turnover rates as part-time employees seek opportunities that offer more hours, higher pay, or career advancement. You will need to anticipate and budget for these shorter tenures and more frequent recruitment needs. This can be particularly challenging if you rely on part-time employees for essential business functions.
Potentially Lower Engagement
Part-time employees may not develop the same level of connection to your company culture and mission as full-time employees. They simply spend less time immersed in the work environment and interacting with colleagues. While this is not universally true—many part-time employees are highly engaged and high-performing—reduced hours can make it more difficult to cultivate loyalty and motivation among part-time workers.
The Financial Aspects of Hiring Part-Time Employees
A primary consideration in part-time hiring is, naturally, cost. As previously mentioned, part-time employees often entail lower costs compared to full-time employees. However, there are nuances in the cost equation that are important to understand.
Superficially, part-time costs appear straightforward: you generally pay for fewer hours of work at a lower salary and benefits rate. If a full-time employee in a particular role earns $40,000 annually and is eligible for your comprehensive benefits package, a part-time employee in the same role might earn half that amount and receive limited benefits, such as paid time off.
However, several less apparent costs should be factored in:
- Recruitment and Onboarding: The time and resources invested in finding, screening, and training a new hire are largely consistent regardless of whether they are part-time or full-time. Therefore, higher part-time turnover translates to increased spending on these recurring costs.
- Benefit Thresholds: Even if you are not obligated to provide benefits to all part-time employees, some may surpass the 30-hour threshold for ACA compliance, necessitating health coverage, a significant expense to budget for.
- Overtime Compensation: Non-exempt part-time employees are still entitled to overtime pay when they work over 40 hours in a week. Inadequate hour tracking can lead to unexpected overtime costs.
- Administrative Overhead: Managing a larger number of part-time employees can be more administratively complex than managing a smaller full-time team. More personnel increases the time spent on scheduling, payroll processing, and performance management.
Considering these complexities, meticulous workforce planning is essential. Employers must evaluate the full spectrum of costs and their specific labor needs when deciding between part-time and full-time hiring strategies.
