Conversion of Fixed-Term to Unlimited Contracts: Rules & EOSB Impact (Article 55)

Article 55 of the Saudi Labor Law establishes the legal mechanism for Contract Conversion. It dictates that a Fixed-Term Contract automatically transforms into an Unlimited Contract after three consecutive renewals or four years of continuous service, fundamentally altering the worker’s resignation rights and End of Service Benefit (EOSB) entitlements.

Article 55 is a statutory provision that automatically converts a limited employment contract into an indefinite agreement if the parties continue the relationship beyond three renewals or four total years, protecting the worker’s long-term employment rights.

The Legal Framework of Contract Conversion (Article 55)

The Saudi Labor Law prevents employers from keeping workers in perpetual short-term agreements. Under Article 55, an employment contract legally transforms into an Unlimited Contract if the employer and employee continue to implement it under specific statutory conditions. The two distinct triggers for automatic conversion are listed below:

1. The Three Consecutive Renewals Rule

If a Fixed-Term Contract contains a renewal clause and is renewed for three consecutive terms, the agreement automatically converts into an Unlimited Contract upon the initiation of the fourth term.

2. The Four Years of Service Rule

If the original contract term combined with the renewal periods amounts to exactly four years, and the parties continue to execute the work, the contract transforms into an Unlimited Contract, whichever condition occurs first.

The Exception: Expatriate Workers and Article 37

The conversion mechanism under Article 55 is subject to a strict legal exception for non-Saudi workers. Article 37 mandates that expatriate employment contracts must remain written and for a specified period. Therefore, an expatriate’s contract never legally converts to an Unlimited Contract, regardless of the number of Consecutive Renewals or years of service.

The Impact of Conversion on Resignation and EOSB

The transformation from a limited to an indefinite agreement drastically shifts the legal liabilities for both parties. Understanding the difference between Saudi Limited vs Unlimited Contracts: Liability is critical, as the Notice Period and termination penalties change entirely.

For Saudi nationals whose contracts convert, initiating a resignation shifts from an unlawful early termination penalty to a lawful Termination of Unlimited Contract: Notice Period & EOSB, requiring a standard 60-day notice and granting the standard resignation End of Service Benefit (EOSB) tiers.
