MLC 2006: Seafarer Employment Agreement Requirements Explained

The Maritime Labour Convention and Seafarer Employment

The Maritime Labour Convention, 2006 (MLC 2006) -- often called the "seafarers' bill of rights" -- establishes comprehensive minimum standards for working and living conditions at sea. Adopted by the International Labour Organization (ILO) and ratified by over 100 maritime nations, MLC 2006 sets out requirements covering employment agreements, wages, working hours, leave, repatriation, accommodation, medical care, and social security protection. For ship managers and manning agencies, MLC 2006 compliance is not discretionary -- it is enforced through flag state inspections, port state control, and the Maritime Labour Certificate that every vessel of 500 GT or above must carry.

The Seafarer Employment Agreement (SEA) is the foundational document of MLC compliance. Regulation 2.1 and Standard A2.1 set out the specific requirements for these agreements, and compliance teams must ensure that every SEA issued meets these standards precisely.

Minimum Age Requirements (Regulation 1.1)

MLC 2006 establishes clear minimum age requirements for seafarer employment. No person below the age of 16 may be employed on a ship. Night work (defined as at least nine consecutive hours between midnight and 5 a.m.) is prohibited for seafarers under 18. Hazardous work -- including work with dangerous machinery, equipment, or substances -- is also prohibited for those under 18, except where authorized for training purposes under strict supervision.

Ship managers must verify age requirements at the point of employment and ensure that contract start dates, vessel assignments, and duty rosters comply with these restrictions. Automated age verification at the recruitment stage prevents non-compliant employment from proceeding.

Medical Fitness (Regulation 1.2)

Every seafarer must hold a valid medical fitness certificate before serving on a ship. MLC 2006 requires that medical certificates are issued by a qualified medical practitioner recognized by the flag state, and that the examination meets the standards set by that flag state. Medical certificates are generally valid for a maximum of two years, reduced to one year for seafarers under 18. Colour vision testing may have different validity periods.

The medical fitness certificate must confirm that the seafarer is medically fit for the duties they will perform at sea, including visual acuity, hearing, and physical capacity. Ship managers must track medical certificate validity alongside other crew documentation and ensure that no seafarer boards a vessel with an expired or insufficient medical certificate.

Seafarer Employment Agreement Requirements (Regulation 2.1)

Standard A2.1 specifies that every SEA must be in writing, signed by both the seafarer and the shipowner (or their representative), and must contain the following particulars at minimum:

• The seafarer's full name, date of birth, and birthplace
• The shipowner's name and address
• The place and date of the agreement
• The capacity in which the seafarer is employed (rank/position)
• The amount of wages or the formula for calculating them
• The amount of paid annual leave or the formula for calculating it
• The termination provisions, including notice periods
• Health and social security protection benefits
• The seafarer's entitlement to repatriation
• Reference to the applicable CBA, where relevant

The agreement must be available to the seafarer in a language they understand. A copy must be carried on board, and another must be available ashore. The seafarer must have the opportunity to review the agreement and seek advice before signing.

Leave Entitlement (Standard A2.4)

MLC 2006 establishes a minimum annual leave entitlement of 2.5 calendar days per month of employment. This leave entitlement accrues continuously from the first day of the employment agreement and cannot be replaced by a payment in lieu, except where the employment is terminated. Justified absences from work -- such as illness, injury, or authorized shore leave -- do not count against the annual leave entitlement.

For ship managers, accurate leave balance tracking is essential. The system must calculate accrued leave based on service days, track leave taken, and ensure that seafarers are not deployed on consecutive contracts that deny them their minimum leave entitlement. When planning crew changes, the available leave balance should be verified to confirm that the seafarer has received adequate rest between contracts.

Wage Standards (Regulation 2.2)

Wages must be paid at least monthly, in a currency agreed upon in the employment agreement or determined by applicable laws or collective bargaining agreements. Seafarers have the right to transmit all or part of their earnings to their families or dependants, and the shipowner must ensure that a system exists for this purpose -- typically through home allotment arrangements.

Wage statements must be provided to each seafarer, showing the amount of wages paid, any deductions made, the exchange rate used for currency conversion, and the allotment amounts transmitted. These records must be maintained and available for inspection.

Working Hours and Rest Periods (Regulation 2.3)

MLC 2006 sets maximum working hours of 14 hours in any 24-hour period and 72 hours in any 7-day period, or minimum rest hours of 10 hours in any 24-hour period and 77 hours in any 7-day period. Rest hours may be divided into no more than two periods, one of which must be at least 6 hours. The interval between consecutive periods of rest must not exceed 14 hours. These limits align with (and are cross-referenced to) the STCW Convention requirements for watchkeeping personnel.

Repatriation (Regulation 2.5)

Seafarers are entitled to repatriation at the shipowner's expense at the end of their employment agreement, or when the agreement is terminated by the shipowner or seafarer for justified reasons. The maximum period of service before repatriation entitlement must not exceed 11 months. The shipowner must provide financial security to ensure that repatriation can be arranged even in cases of abandonment.

Generating Compliant Contracts Digitally

Digital contract generation systems can enforce MLC compliance by design. When a crew management system generates an SEA, it can automatically populate all required particulars from the crew database and applicable wage scales, verify that all mandatory clauses are included, calculate leave entitlement based on the planned contract duration, apply the correct CBA terms, and present the agreement for review and digital signature.

E-CMS by Sealogic generates MLC-compliant Seafarer Employment Agreements with embedded digital signature pads and QR-code verification. The system pulls seafarer data, vessel assignment details, and applicable wage scales to produce contracts that meet Standard A2.1 requirements. Leave entitlements are calculated automatically, and the signed agreement is stored digitally with full audit trail -- accessible both onboard and ashore as MLC requires.

Key Takeaways

• MLC 2006 compliance is mandatory for all vessels of 500 GT and above from ratifying nations, enforced through flag state inspections and PSC.
• The Seafarer Employment Agreement must contain specific particulars defined in Standard A2.1, in a language the seafarer understands.
• Leave entitlement accrues at a minimum of 2.5 calendar days per month and must be tracked accurately across contracts.
• Working hour limits and rest period requirements must be monitored and recorded systematically.
• Digital contract generation with automated compliance checks is the most reliable way to ensure every SEA meets MLC standards.
