If your onboard complaint is not being resolved, the safest formal path under the Maritime Labour Convention is to use the ship’s onboard complaint procedure first, keep a clear written record of what happened and what you asked for, and then escalate through the channels allowed by your ship’s procedure and applicable law, which may include the master, the shipowner, and then flag-State or port-State authorities. Under MLC Regulation 5.1.5, there must be an onboard complaint procedure, and seafarers should be protected against victimization for making a complaint. That protection matters, but the exact escalation route can still vary by flag State, your seafarer employment agreement, and any collective bargaining agreement, so always compare this guide with the procedure given on your ship.
The main idea is simple: complain early, complain clearly, and complain in a way that can be checked later. Ask for the official onboard complaint procedure if you do not already have it. The MLC framework says seafarers should receive a copy of the onboard complaint procedure and information about relevant contacts. Two good starting points for the legal framework are the ILO Maritime Labour Convention and the UK MCA’s plain-language overview of seafarers’ MLC rights at UK MCA Maritime Labour Convention overview. For practical background on how the Convention works, see the 2026 ILO MLC FAQ.
What the MLC officially requires, and what may depend on your ship
Start by separating legal minimum standards from company practice. The official MLC point here is narrow but important: Regulation 5.1.5 establishes onboard complaint procedures and protection against victimization. It also supports the idea that seafarers should have the procedure and know relevant contacts. That is the evidence-based floor.
Everything beyond that may depend on the flag State’s implementing rules, the shipowner’s documented procedure, your contract terms, and any collective bargaining agreement. For example, your company may require a complaint form, a reporting line through a department head first, or a confidential reporting channel. Those can be valid company procedures if they do not take away the minimum MLC protection. But they are not the same thing as the MLC text itself.
So when you are deciding how to escalate, ask three questions:
- What does the ship’s official onboard complaint procedure say?
- What contacts are listed for escalation beyond the ship?
- Are there any flag-State, SEA, or CBA rules that change the reporting route or add representation rights?
If you do not know the answer, ask for the written procedure. That request is itself reasonable and should not be treated as misconduct.
When an onboard issue becomes a formal complaint
Not every workplace problem starts as a formal complaint. Many issues are solved informally by speaking to the responsible officer, department head, or another person identified in the ship’s procedure. But once the issue is serious, repeated, ignored, or sensitive enough that you need a clear record, move to a formal complaint.
A formal complaint is usually the right next step when:
- You already raised the issue and nothing changed.
- You were told to wait but were given no clear response.
- The matter affects your rights, working or living conditions, or fair treatment.
- You are worried that oral reporting alone can be denied later.
- You fear retaliation and want the protection of a documented process.
Making the complaint formal does not mean being aggressive. It means being precise. Focus on facts, dates, who you reported to, what you asked for, and what response you received. Avoid insults, rumours, or broad accusations you cannot support.
How to escalate safely when your complaint is unresolved
Safe escalation means two things at the same time: you continue using the proper reporting path, and you reduce avoidable personal risk. Under the MLC, protection against victimization is part of the framework, but practical caution still matters. Use the ship’s procedure, keep records, and disclose only what is necessary.
Step-by-step checklist
- Get the official complaint procedure. Find your copy or ask for it. Check who you should complain to first and what higher contacts are listed.
- Write a short factual summary. Include the issue, dates, places, who was involved directly, and what outcome you want.
- Raise it at the first formal level required. This may be a supervisor, head of department, or another person named in the onboard procedure.
- Ask for written acknowledgment if possible. If the procedure uses forms or email, keep a copy. If the report is oral, make your own dated note of when and to whom you spoke.
- Set out your requested action clearly. For example: investigation, correction of a living condition issue, confirmation of leave records, or referral to the proper authority.
- Keep a complaint log. Record each step: date, person contacted, summary of what was said, and any follow-up promised.
- If unresolved, escalate to the next level in the procedure. Depending on the procedure and applicable law, this may include the master or the shipowner.
- Use only necessary personal data. Document dates, facts, and requests without exposing private details of other crew members unless strictly needed for the complaint.
- State any concern about victimization. If you fear retaliation, say so calmly in writing and refer to the complaint procedure’s protection framework.
- If the onboard route fails, use the external contacts provided. Appropriate paths may include the shipowner, flag-State authority, or port-State authority as provided by law and the ship’s procedure.
- Keep copies in a secure place. Preserve your notes, submissions, and responses so you can show the complaint history if asked.
- Stay professional onboard. Continue to follow lawful instructions and safety procedures while the complaint is being handled, unless a separate emergency or safety rule requires immediate action through the ship’s safety system.
The purpose of this checklist is not to make your complaint look legalistic. It is to make it traceable. Traceability often matters more than strong language.
What to write in a formal onboard complaint
A useful complaint is specific enough to investigate and limited enough to protect you from side arguments. You do not need to write a long statement. In many cases, one page is enough.
Include these core points:
- Your name, rank, vessel name, and date.
- A short subject line.
- The factual issue: what happened, where, and when.
- Who you already reported it to and on what date.
- Why it remains unresolved.
- What action or answer you are requesting.
- A note that you are using the onboard complaint procedure.
- If relevant, a short line saying you request protection against victimization.
What not to include is equally important. Do not add gossip. Do not accuse other crew members of private matters unrelated to your complaint. Do not attach someone else’s personal information unless it is necessary to explain the issue and permitted by the reporting process. The fact pack for this guide supports a practical rule: document dates, facts, and requests without exposing private details of other crew members.
Simple complaint template
Subject: Formal onboard complaint under ship’s complaint procedure
I, [name and rank], submit this formal complaint regarding [brief issue].
Facts: On [date] at/about [time/place], the following occurred: [short factual description].
Previous reporting: I reported this matter to [name/rank] on [date]. The response was [short summary], and the matter remains unresolved.
Request: I request [investigation/correction/written response/referral to next level under procedure].
Records: I attach or can provide my notes of dates, reports made, and any related messages or documents.
Confidentiality and fair treatment: I ask that this complaint be handled according to the ship’s onboard complaint procedure. If relevant, I also ask for protection against victimization.
Signed: [name]
Rank: [rank]
Date: [date]
This template is an example, not an MLC-required form. Your company or flag-State procedure may require a different format.
Choosing the next escalation level: master, shipowner, flag State, or port State
The MLC-based reporting path often moves from onboard handling to higher internal or external channels, but the exact sequence can vary. The fact pack for this article allows these general paths: the master, shipowner, flag-State authorities, and port-State authorities as provided by law. The key phrase is “as provided by law.” Do not assume the same order applies on every ship.
In practice, you should usually follow the route written in the onboard complaint procedure unless there is a lawful reason to use another contact listed there. For many complaints, the master is a central escalation point on board. If the complaint concerns a matter the master cannot or does not resolve, the next step may be the shipowner contact named in the procedure.
External escalation may become appropriate when:
- The onboard process has been used but the issue remains unresolved.
- You are directed by the written procedure to contact a shore-based person or authority.
- The matter is serious enough that the procedure or law allows direct outside reporting.
- You are in port and the procedure identifies port-State channels for complaints.
The ILO Maritime Labour Convention provides the treaty framework, while the UK MCA Maritime Labour Convention overview explains in plain terms that MLC sets minimum rights for many working and living conditions. Use those sources to understand the system, but for your actual next contact, rely first on the contacts listed in your shipboard procedure and applicable flag-State implementation.
How to protect yourself from victimization without making the complaint weaker
Protection against victimization is part of the MLC complaint framework, but it works best when your own conduct is disciplined. A complaint is stronger when it is factual, respectful, and tied to the written procedure. That approach reduces opportunities for the issue to be reframed as a personal conflict.
Practical ways to protect yourself include:
- Use the official complaint route rather than spreading the issue informally.
- Keep copies of your own complaint and responses.
- Make notes immediately after meetings or conversations.
- Ask that important instructions or outcomes be confirmed in writing where possible.
- Do not discuss other crew members’ private information unless necessary for the complaint.
- Do not post complaint details publicly or on social media while it is being handled.
- If you feel retaliation is happening, record the facts the same way you recorded the original issue.
Victimization concerns should be described with facts, not conclusions. Instead of writing “I am being targeted,” write what changed: for example, “After I submitted my complaint on [date], [specific action] occurred.” Keep the complaint process and any later retaliation concerns documented separately but linked by date.
Illustrative scenario: unresolved accommodation complaint
A ratings crewmember reports a repeated accommodation problem affecting rest. He first tells his immediate superior and later repeats the concern after nothing changes. The issue still continues. He wants to escalate safely without causing conflict with the rest of the crew.
First, he checks the ship’s onboard complaint procedure and confirms the formal route. He writes a short complaint note listing the dates he reported the issue, the location onboard, the practical effect on his living conditions, and the action requested. He avoids naming other crewmembers who also complained privately to him because their private details are not needed to explain his own complaint.
He submits the complaint at the next formal level required by the procedure and keeps a copy. He asks for written acknowledgment if available. When there is still no resolution, he escalates to the next contact identified in the procedure, which may be the master or a shipowner representative, depending on the route set out on that vessel.
In his escalation note, he does not rewrite the whole story emotionally. He simply states that he made a formal complaint on a certain date, that the matter remains unresolved, and that he requests the next-stage review under the complaint procedure. If he is concerned about backlash, he includes one line asking that the matter be handled in line with the onboard complaint procedure and protection against victimization. If the onboard route still fails, he checks the listed external contacts for possible flag-State or port-State reporting according to law and the ship’s procedure.
This scenario is an example only. It illustrates method, not a guaranteed legal sequence for every ship.
Common mistakes that can weaken an otherwise valid complaint
Many seafarers have a real issue but lose momentum because the complaint becomes unclear. Avoid these common problems:
- Waiting too long to write things down. Memory becomes less reliable over time.
- Making the complaint too broad. A focused complaint is easier to investigate and answer.
- Mixing facts with assumptions. Write what happened first; identify concerns separately.
- Skipping the official route without checking the procedure. This can create delay unless the law or procedure allows direct outside reporting.
- Including unnecessary personal details about others. This may distract from the issue and create privacy concerns.
- Using insulting or threatening language. Strong facts are more effective than strong words.
- Failing to state the requested outcome. Decision-makers need to know what you are asking them to do.
If you are unsure whether a detail belongs in the complaint, ask yourself: does this fact help prove what happened, show that I followed the procedure, or explain what remedy I want? If not, leave it out.
Practical FAQ for seafarers
Do I have to complain only to my immediate superior first?
Not always. Follow the written onboard complaint procedure on your ship. Some procedures start with a supervisor or department head; others may allow another route depending on the issue. Because implementation can vary, check the actual procedure you were given.
Can I go straight to an external authority?
Sometimes the law or the ship’s procedure may allow external reporting, but the exact circumstances vary. Appropriate paths may include the shipowner, flag-State authorities, and port-State authorities as provided by law. Do not assume direct external reporting is always the first step unless your procedure or applicable law says so.
What if I never received the onboard complaint procedure?
Ask for it immediately and make a note of your request. The MLC framework says seafarers should receive a copy of the onboard complaint procedure and information about relevant contacts.
What if I am afraid of retaliation?
Use the formal procedure, keep written records, and state briefly that you request protection against victimization. Record any later retaliatory acts factually and separately. The MLC framework includes protection against victimization, but local implementation details can vary.
Should I include names of other crew who told me similar things?
Only if necessary and appropriate under the procedure. A safer default is to document your own complaint with dates, facts, and requests without exposing private details of other crew members.
Do I need legal words or treaty quotations?
No. Plain factual language is usually better. You may refer to the ship’s onboard complaint procedure and, if useful, note that the process is part of the MLC framework.
Where can I read more from official sources?
Use the official MLC pages at the ILO Maritime Labour Convention, the practical government summary at the UK MCA Maritime Labour Convention overview, and the 2026 ILO MLC FAQ for general explanatory guidance.
A simple final action plan
If your complaint is unresolved, do not let it remain a verbal disagreement. Turn it into a formal, dated, factual complaint under the ship’s onboard complaint procedure. Ask for the procedure if you do not have it. Follow the stated route. Keep a record of every step. Escalate to the next level named in the procedure, which may include the master, the shipowner, and then external flag-State or port-State channels as provided by law. Protect yourself by staying factual, limiting unnecessary personal details, and noting any concern about victimization.
This is the most practical way to escalate safely under the MLC framework without guessing at rights that may vary by flag State, SEA, or CBA. The process may feel formal, but formality is what helps make an unresolved complaint visible, reviewable, and harder to ignore.
