Explore standard working hours and overtime regulations in Belgium

Updated on April 27, 2025

Belgium has established regulations governing working time to ensure employee well-being and fair labor practices. These rules define standard working hours, limits on maximum hours, requirements for rest periods, and conditions for overtime work. Employers operating in Belgium must adhere strictly to these regulations to remain compliant with national labor law.

Understanding and implementing these rules correctly is crucial for businesses employing staff in Belgium. Compliance involves not only setting appropriate schedules but also accurately tracking working time and compensating employees according to legal requirements for standard hours, overtime, and specific work patterns like night or weekend shifts.

Standard Working Hours and Workweek Structure

The standard legal working time in Belgium is generally set at 38 hours per week. This is the reference point for calculating overtime and ensuring compliance. While 38 hours is the standard, collective bargaining agreements (CBAs) at sector or company level may stipulate a lower average weekly working time.

The maximum daily working time is typically limited to 8 hours. However, this can be extended to 9 hours per day if the average weekly working time over a reference period (usually a quarter or a year) does not exceed 38 hours. In specific circumstances, such as continuous work or work organized in shifts, daily limits can be higher, provided the weekly average is respected.

The maximum weekly working time is generally capped at 40 hours. However, the absolute maximum working time, including overtime, cannot exceed 11 hours per day and 50 hours per week under normal circumstances. Exceptions exist for specific sectors or urgent work, but these are subject to strict conditions and often require prior authorization.

Overtime Regulations and Compensation

Overtime is defined as any work performed beyond the standard daily or weekly limits set by law or applicable CBA. Overtime is generally permitted only in specific, legally defined circumstances, such as:

  • Exceptional workload or unforeseen circumstances
  • Urgent work on machinery or equipment
  • Work required due to force majeure

There are limits on the amount of overtime that can be performed. The general annual limit for voluntary overtime is 120 hours per employee, which can be increased to 220 hours through a sector-level CBA. Overtime performed due to exceptional circumstances or force majeure does not count towards these limits but is subject to other restrictions.

Overtime work must be compensated with a premium in addition to the normal hourly wage. The standard overtime rates are:

Type of Overtime Work Minimum Premium Rate Total Compensation (Wage + Premium)
Weekdays (normal hours) 50% 150%
Sundays and Public Holidays 100% 200%

In certain cases, overtime hours must also be compensated with compensatory rest time. The principle is that for every hour of overtime worked, an employee is entitled to compensatory rest, typically within a specific timeframe (e.g., within the reference period). The payment of the premium does not always replace the requirement for compensatory rest.

Rest Periods and Break Entitlements

Belgian law mandates minimum rest periods to ensure employee recovery.

  • Daily Rest: Employees are entitled to a minimum of 11 consecutive hours of rest between two working days.
  • Weekly Rest: Employees are entitled to a minimum of 24 consecutive hours of rest per week, which must include Sunday as a general rule. In certain sectors or under specific conditions, this weekly rest can be granted on another day.

Employees are also entitled to breaks during the workday. The general rule is:

Working Time Duration Minimum Break Entitlement
More than 6 hours At least 15 minutes

Specific CBAs may provide for longer or more frequent breaks. Breaks are generally unpaid unless otherwise stipulated by a CBA or company policy.

Night and Weekend Work Regulations

Work performed between 8 PM and 6 AM is generally considered night work and is subject to specific regulations. Night work is typically prohibited, but numerous exceptions exist for specific sectors (e.g., healthcare, hospitality, transport) or types of work. Employees performing night work may be entitled to specific allowances or compensation, as well as additional rest periods or reduced working hours, depending on applicable CBAs.

Work on Sundays is generally prohibited, with exceptions similar to those for night work (e.g., continuous processes, public services, retail under specific conditions). Employees working on Sundays are entitled to a compensatory rest day within the following six days and often receive a premium (as mentioned in the overtime section, 100% premium for Sunday work).

Working Time Recording Obligations

Employers in Belgium have a legal obligation to maintain accurate records of their employees' working time. This is essential for demonstrating compliance with legal limits on daily and weekly working hours, rest periods, and overtime regulations.

The recording system must be reliable and allow authorities to verify compliance easily. While the specific method is not strictly prescribed (it can be manual, mechanical, or electronic), it must accurately show:

  • The start and end time of each working day.
  • The duration of breaks that are counted as working time.
  • The total daily and weekly working hours.
  • Any overtime performed.

These records must be kept for a specific period (typically five years) and made available to the labor inspectorate upon request. Failure to maintain accurate and accessible working time records can result in significant penalties for the employer.
