The short answer is that there is no single legal definition of "part-time" hours in most English-speaking countries. Instead, it is defined by your employer’s policy and the local labor laws. Generally, working less than 30 to 35 hours per week is considered part-time. However, the exact number can range from as few as 10 hours to 29 hours, depending on the industry and the specific role.
From a recruitment and employer branding perspective, clearly defining part-time hours is crucial. Job seekers often misinterpret "part-time" as a flexible side hustle, while employers may see it as a fixed schedule of 20 hours. This mismatch leads to high turnover. To avoid this, companies should specify the exact weekly hours in the job description. For example, "Part-time, 20 hours per week, Monday to Friday, 2 PM to 6 PM."
Here is a breakdown of common definitions across major English-speaking markets:
| Region | Typical Part-Time Definition | Common Legal Threshold |
|---|
| United States | Fewer than 30-35 hours/week | No federal standard; varies by company (Affordable Care Act defines 30+ as full-time) |
| United Kingdom | Fewer than 35 hours/week | No statutory definition; determined by contract |
| Australia | Fewer than 38 hours/week | Defined by award or enterprise agreement; usually 20-30 hours |
| Canada | Fewer than 30 hours/week | Determined by employer; no federal standard |
| Ireland | Fewer than 35 hours/week | No legal definition; based on employer policy |
The key takeaway for job seekers: always ask for the minimum and maximum weekly hours during the interview. For employers, standardizing your part-time definition improves your talent retention rate and ensures compliance with local labor laws. A structured interview process should include a clear question about schedule expectations to avoid misunderstandings.
