Understanding Belgium's Working Time Regulations: A Guide for International Employers

Maximum Working Hours and Overtime Legislation in Belgium

Belgium's employment framework is governed by comprehensive labor laws that establish clear parameters for working hours and overtime compensation. The Work Act (Arbeidswet/Loi sur le travail) outlines fundamental provisions regarding employee schedules and rest periods, while the Overtime Act (Loi sur les heures supplémentaires/Wet op de overuren) specifies compensation standards for additional work hours.

Standard Working Hour Limitations

Belgium typically operates on a five-day workweek system with maximum daily working hours capped at eight and weekly limits not exceeding 38 hours. Work activities are generally restricted to the timeframe between 6:00 AM and 8:00 PM, reflecting the country's prohibition against night work in most circumstances.

Several notable exceptions exist to these standard limitations:

Continuous shift work: Maximum 11 hours daily and 50 hours weekly
Technically necessary continuous operations: Up to 12 hours daily and 50 hours weekly, extendable to 56 hours when distributed across seven days

These exceptions operate within legal boundaries without requiring prior authorization. However, other scenarios necessitate formal approval through governmental decrees:

Specific industrial sectors unable to comply with standard hour restrictions
Preparation or follow-up work occurring outside normal production schedules

Across all employment scenarios, the maximum allowable working time averages 47.5 hours weekly within reference periods, with annual extensions capped at 180 additional hours. The approval process involves multiple stages, including consultation with worker representatives and regional labor authorities.

Overtime Compensation Structure

Overtime constitutes work performed beyond contractual obligations, with premium compensation applying to hours exceeding nine daily or 40 weekly (or collectively bargained thresholds). The compensation structure includes:

Overtime Type	Premium Rate
Standard overtime	20% additional compensation
Saturday work	50% premium
Sunday and public holidays	100% additional payment

Employees may alternatively opt for compensatory time off, accruing one rest day for every eight overtime hours. This time must be utilized within twelve months following the overtime work period.

Employment Contract Framework

Belgian employment relationships are formalized through contracts categorized by worker status and engagement terms. The legal framework distinguishes four primary worker classifications:

Blue-collar workers (manual laborers)
White-collar employees
Commercial representatives
Domestic workers

Additional regulations govern specialized categories including remote workers, student employees, and temporary agency staff. Contract determination requires assessment of:

Nature of work performed
Contractual framework specifics
Employment duration terms
Weekly hour commitments

Contracts may be structured as indefinite, fixed-term, specific-task, or temporary arrangements. Full-time contracts align with standard weekly hours (typically 38), while part-time agreements involve regularly reduced schedules.

Probationary Period Provisions

Recent legislative changes have substantially limited probationary periods in Belgian employment contracts. Such arrangements are now permissible only for student workers, temporary employees, and during the initial three days of temporary agency assignments. Standard permanent employment relationships no longer incorporate trial periods.
