In 2023, U.S. employers reported 2.6 million nonfatal workplace injuries and illnesses - an alarming reminder that unsafe conditions are still far too common.
Every employee deserves a safe, healthy workplace, and employers are legally and ethically bound to provide one.
Organizations like OSHA and the ILO set global standards to uphold these rights - filing a complaint is how you exercise yours.
When risks go unchecked, it’s not just your safety on the line, it’s everyone’s.
Whether it’s blocked exits, faulty machinery, or chemical exposure, a formal complaint letter can spark real change.
Here’s how to write a workplace complaint letter that gets taken seriously in 6 clear, actionable steps.
Step 1: Precise Identification and Clear Statement of Purpose
Your letter must immediately convey its seriousness and intent.
- Your Information: Full name, job title/department, employee ID (if applicable), and contact details.
- Recipient’s Information: Address the letter to the designated safety officer, your direct supervisor, department head, or Human Resources, according to your company’s internal reporting procedures for safety concerns.
- Date of Submission: Crucial for record-keeping.
- Direct Subject Line: For example: "Formal Complaint: Urgent Safety Hazard Regarding [Specific Hazard, e.g., Exposed Electrical Wiring in Warehouse Area B]."
- Clear Opening Statement: State upfront that you are writing to formally report specific unsafe working conditions and your desire for immediate corrective action. Example: "I am writing to formally report a serious safety hazard concerning [brief description of hazard, e.g., a recurring chemical spill] in the [specific location] that poses an immediate risk to employee health and safety."

Step 2: Detailed Description of Each Hazard or Unsafe Condition
Vagueness is the enemy of an effective safety complaint letter. For each hazard:
- What is the hazard? Be specific. (e.g., "frayed and exposed electrical wiring," "lack of proper ventilation when using [Specific Chemical]," "broken safety guard on the [Machine Name]").
- Where is it located? Provide the exact location (e.g., "adjacent to workstation 12 in the assembly area," "the main stairwell between the 2nd and 3rd floors," "all emergency exit doors on the east side of the building").
- When was it observed? Note the date and, if relevant, time you (and others, if applicable) observed the hazard. If it’s ongoing, state that.
- How is it unsafe? What are the potential risks? Explain why the condition is dangerous. Describe the potential injuries or illnesses that could result (e.g., "This exposed wiring poses a significant risk of electric shock and fire." "The lack of ventilation could lead to respiratory problems or chemical exposure symptoms for employees working with [Specific Chemical]." "The broken guard could result in serious hand injuries to operators.").
- Frequency and Duration: If it's a recurring issue, note how often it occurs and for how long it has been a concern.
Pro Tip: If safe to do so, take clear photographs or videos of the hazard(s) as visual evidence. Mention in your letter that you have this documentation available. Never put yourself or others at further risk to obtain evidence.

Step 3: Documenting Impact or Potential Impact (Incidents & Near Misses)
If the unsafe condition has already led to incidents or near misses, include these details.
- Past Incidents: Describe any injuries, illnesses, or property damage that have already occurred due to the hazard. Include dates, who was affected, and the nature of the incident.
- Near Misses: Detail any close calls or situations where an accident was narrowly averted. This helps illustrate the ongoing risk. Example: "On [Date], a colleague, [Colleague's Name, if they consent to be named or if it’s a publicly known incident], reported dizziness after working in the improperly ventilated area for two hours." OR "On [Date], a pallet nearly fell from the damaged shelving unit in Aisle 5, narrowly missing an employee."
The existence of such hazards, especially if ignored, can sometimes contribute to what employees feel is a hostile work environment, where safety concerns are not taken seriously.
Step 4: Reference to Safety Regulations, Standards, or Company Policies
If you are aware of specific safety rules being violated, mentioning them can add weight to your complaint.
- Company Safety Policies: Refer to your company’s own safety manual or stated procedures. Example: "This condition appears to violate Section 5.3 of our company’s 'Occupational Health and Safety Policy' regarding machine guarding."
- General/Known Industry Standards: You can refer to generally accepted safety practices for your industry.
- Specific Regulations (Use with Caution): If you know a specific OSHA, HSE, or other relevant regulation, you can mention it. However, be careful not to misinterpret legal codes if you are not an expert. It's often safer to describe the hazard clearly and let the company (or an inspector, if it comes to that) determine the exact regulatory violations.

Step 5: Requesting Specific Corrective Actions
Don’t just point out the problem; suggest a solution or request specific actions.
- Be Clear and Actionable: What do you want the employer to do? Example: "I request that the frayed electrical wiring be immediately repaired or replaced by a qualified electrician."
- Interim Measures: If a permanent fix will take time, suggest temporary measures to reduce risk. Example: "Pending full repair, I request that the area with the exposed wiring be cordoned off and warning signs posted."

Step 6: Providing or Offering Supporting Evidence
Tangible proof strengthens your case.
- List Evidence: Mention any evidence you have, such as photographs, videos, your personal log of observations, witness statements (if witnesses agree), or copies of any previous informal communications about the issue.
- Offer to Share: State that you are willing to provide this evidence. Example: "I have photographs of the damaged equipment and a log of dates when the issue was observed, which I can provide upon request."
Pro Tip: When documenting, focus on facts: what you saw, heard, or experienced. Avoid speculation about why the hazard exists or blaming individuals unless their actions are directly part of the hazard (e.g., consistently removing a safety guard).
Sending the Letter & Next Steps
- Follow Company Protocol: Submit your letter according to your company’s established procedure for reporting safety concerns.
- Keep Copies: Always retain a copy of your signed letter and any attachments.
- Proof of Delivery: Send it via a method that provides proof of receipt (e.g., email with read receipt, hand-delivery with a signed acknowledgment, or certified mail).
- Allow Time for Response: Give your employer a reasonable time frame to investigate and respond.
- External Reporting: If your employer does not address the serious hazards, you have the right to report them to the relevant external regulatory agency (e.g., OSHA in the U.S.). These agencies typically offer whistleblower protection.
