Employers expanding into the United States need to be aware of how working time is structured and regulated. The country has a relatively flexible system compared with many other markets, largely shaped by federal law, and supplemented by state-specific requirements. Working hours in the United States are guided by the Fair Labor Standards Act (FLSA), but practices also vary by industry, occupation, and employer policy.
United States labour laws on working hours
Under federal law, a standard full-time schedule is typically considered 40 hours per week, often Monday to Friday. Employees who work fewer than 30 hours are generally treated as part-time, and they may not always be eligible for benefits such as employer-provided health insurance (U.S. Department of Labor).
Overtime is a key feature of United States labour laws on work hours. Non-exempt employees must be paid one-and-a-half times their regular hourly rate for every hour worked beyond 40 in a week. Importantly, employers are not required to pay extra simply because employees work weekends or holidays, unless overtime is triggered. Exempt employees—those in executive, administrative, or professional roles who meet salary thresholds—are not entitled to overtime pay.
Some states add further protections, such as requiring premium pay for working seven consecutive days or guaranteeing a minimum rest period. These variations make it important for employers to review both federal and state obligations when setting schedules.
Average working hours in the United States
The average hours worked per week in the United States remain close to the widely accepted 40-hour standard, but actual figures vary. A full-time schedule of 40 hours over 52 weeks equates to 2,080 hours per year. However, data from the Organisation for Economic Co-operation and Development (OECD) shows that the average hours worked per year in the U.S. is closer to 1,765–1,800, reflecting time off, holidays, and variations in how jobs are structured.
In practice, not all working time is equally productive. Research suggests that office-based employees often achieve only 2.5 to 4 hours of focused work per day, even if they are contracted for a full 8-hour shift. Despite this, employers still typically rely on the 40-hour week as the benchmark for full-time engagement.
Working hours in the U.S. per day are most often eight, though in many industries longer shifts, compressed workweeks, or flexible arrangements are common.
United States 32-hour workweek
In recent years, debate has emerged around reducing the standard workweek. The “Thirty-Two Hour Workweek Act” (H.R.1332) was introduced to amend the FLSA and redefine the full-time threshold from 40 to 32 hours. If enacted, non-exempt employees would receive overtime pay for hours worked beyond 32 in a week.
The proposed United States 32-hour work week has generated interest from both policymakers and employers. Advocates argue that it could improve work-life balance, reduce burnout, and increase productivity. For businesses, however, it could mean rethinking staffing models, hiring additional workers, or restructuring workloads to cover the same output in fewer hours.
While the bill has not been passed into law, it highlights the evolving conversation around work culture in the U.S. Employers considering long-term workforce planning should monitor these developments closely.
