What's the difference between fixed-term and permanent employment contracts?

Fixed-term contracts have predetermined end dates and limited renewal options, while permanent contracts continue indefinitely until terminated.

The distinction between fixed-term (CDD) and permanent (CDI) employment contracts in Belgium involves significant legal and practical differences that affect both employers and employees.

Contract Duration: Permanent contracts have no predetermined end date and continue until terminated by either party following proper procedures. Fixed-term contracts specify exact start and end dates, automatically expiring without notice requirements.

Renewal Limitations: Fixed-term contracts can be renewed maximum three times within a 24-month period. Exceeding these limits automatically converts the contract to permanent status. Permanent contracts don't face such restrictions.

Termination Rules: Permanent contracts require notice periods based on seniority and proper termination procedures. Fixed-term contracts typically cannot be terminated early without mutual agreement or serious cause, potentially requiring compensation for the remaining contract period.

Job Security: Permanent employees enjoy greater protection against arbitrary dismissal and longer notice periods. Fixed-term employees have less security but may receive end-of-contract compensation in some sectors.

Benefits and Rights: Both contract types generally provide equal access to social security, vacation time, and workplace protections. However, some collective bargaining agreements may differentiate benefits.

Use Cases: Fixed-term contracts suit temporary needs (seasonal work, project-based roles, maternity replacements). Permanent contracts are appropriate for ongoing business functions.

Conversion: Fixed-term contracts may automatically become permanent if legal limits are exceeded or if the employee continues working after contract expiration.

Tom Claeys from Pragmalegis advises careful consideration of business needs when choosing contract types, as improper use of fixed-term contracts can create unexpected permanent employment obligations.
