If the shipowner or manning agency breaches your Seafarer Employment Agreement — failing to pay agreed wages, ending the contract early without cause, withholding allotments, refusing leave, or imposing duties or trading limits beyond the SEA — you have multiple enforcement routes. The first is the on-board complaint procedure under MLC 2006 Standard A5.1.5; from there you can escalate to the flag state, the manning agency's licensing authority, the ITF Inspectorate, and (where contract issues survive into a labour-court action) national labour tribunals. Document every breach contemporaneously.
MLC 2006 Reg. 2.1 (SEA), Standard A2.1 (content of SEA), and Standard A5.1.5 (on-board complaint procedure). National manning-agency licensing legislation: Philippines Republic Act 11641 (DMW) and POEA-SEC; India MS (Recruitment and Placement of Seafarers) Rules 2016; Ukrainian Maradmin licensing. ITF Inspectorate operates on flag-of-convenience vessels under TCC CBAs.
