What Are Part-Time Hours?

Part-time hours describe a work schedule where an employee works fewer hours than what the employer defines as a full-time workweek. This typically means less than 30-35 hours per week, though the specific threshold varies by company and sometimes by law.

Unlike full-time employment, there's no federal legal definition of part-time work. Employers largely determine their own classifications.

Defining Your Part-Time Threshold

Consistency Is Key

Whatever threshold you choose, apply it consistently. Varying definitions between departments or locations creates confusion and potential discrimination issues.

Federal Law Considerations

Fair Labor Standards Act

The FLSA makes no distinction between part-time and full-time for purposes of minimum wage and overtime. Part-time employees are entitled to:

Affordable Care Act

The ACA defines full-time as 30+ hours per week (or 130 hours per month) for determining health insurance requirements.

Employers with 50+ full-time equivalent employees must offer health insurance to employees working 30+ hours or face penalties.

Family and Medical Leave Act

Part-time employees are eligible for FMLA if they've worked:

Part-time employees who meet the hours threshold receive FMLA protection on a pro-rated basis.

State Law Variations

Some states have specific requirements for part-time workers:

Benefits

Certain states require pro-rated benefits for part-time employees (paid sick leave, for example).

Scheduling Laws

Predictive scheduling laws in several cities require:

Equal Treatment

Some jurisdictions require equal treatment of part-time and full-time workers in terms of hourly pay and pro-rated benefits.

Challenges of Part-Time Employment

High Turnover

Part-time positions often see higher turnover due to:

Scheduling Complexity

Coordinating multiple part-time schedules is more complex than managing full-time employees with set schedules.

Training Investment

Training part-time staff who work fewer hours takes proportionally more time and may not yield the same return as training full-time employees.

Communication Gaps

Part-time employees who work varied schedules may miss important communications or feel less connected to the team.

Best Practices

Clear Classification

Define your full-time and part-time thresholds explicitly in writing. Include this in:

Fair Scheduling
