Is finding a healthy working environment as rare as a four-leaf clover these days?

Let's face it, navigating the complexities of workplace dynamics can be a real challenge.

And I bet you've had your fair share of coworker conundrums, just like the rest of us.

Still, the question remains: did we take the right steps to address the issue?

Addressing conflicts and complaints in the workplace is essential for your own well-being.

Not to mention the satisfaction of everyone involved, including employees, clients, and supervisors.

In that spirit, this article provides guidance on how to write a professional email to address complaints about coworkers.

It offers the right language and strategies to ensure your concerns are taken seriously in the workplace.

Let's get started!

Definition of a Complaint Email

An email complaint is a type of written communication that expresses displeasure with a product, service, or experience.

A strong complaint email will outline your issue and your desired course of action in a gentle fashion.


You have more time to consider your response and pick your words wisely when using this communication method.

Your email of complaint must be composed in a clear, succinct, and composed manner.

Reasons for Filing a Complaint Email

Not all intimidation at work is rated equally, so the following are examples of actions that qualify as harassment at work:

  • Threatening Body Language - A coworker who is displaying an angry facial expression or aggressive physical posture can likely give you anxiety and increase your stress level.
  • Emotional Manipulation - A person at work that may take advantage of your insecurities and attempt to control you by dishonest, deceptive, or violent means.
  • Verbal Abuse - A coworker that always tries to weaken the victim's feeling of value and self-confidence, regardless of the exact words used.
  • Abase - A typical form of workplace harassment that involves making a victim feel unimportant, ashamed, or undeserving in a work environment.
  • Physical Contact - It can involve touching, kissing, stroking, embracing, or even just getting too close to a worker to feel uncomfortable, and can lead to sexual harassment.
  • Physical Assault - Threatening or injuring someone else is considered a serious type of physical attack in the workplace.

Given the sensitive nature of the situations discussed above, using email as a means of communication is professional and appropriate, particularly in scenarios where:

✅ you need to handle a serious issue that you can't discuss in person,

need some space to consider your future actions, or

✅ you have been estranged from a colleague and need a formal, documented way to address the issue.

Guideline on How to Compose Email of Complaint against a Coworker

A problem can be resolved more quickly if your complaint letter is presented properly.

1. Frame the Issue

Before filing a complaint, make sure the reasons are valid.
If you are easily annoyed by gum chewing, whistling, or sighing your complaint will most likely get dismissed.

▶️If your actions have contributed to the issue, think about how you could make a greater effort to find a solution on your own, away from management.

2. State Reasons for Writing

Briefly explain why you are writing the letter at the beginning of it.

Explain that you feel it's time to file an official complaint because of several occurrences that have happened between you and the coworker.

Include information if you have already attempted to manage it on your own.


I'm writing to let you know about my disagreement with [worker name], a worker.
I've tried to talk to [worker name] about the issue several times, but he/she won't listen to me or take my feelings into account.

3. Provide Chronology of Events

Write down what transpired between you and the employee. Add the dates of each incident along with a separate list of them.

When reporting what transpired, stay true to the facts and speak impartially.

Also, make sure to support your claims with evidence wherever possible.

Supporting documents may include the following:

  • Witnesses 
  • Textual correspondence
  • Images
  • Screenshots
  • Videos
  • Sound recordings


On Thursday of this week, I spoke with [worker's name] several times regarding her loud talking, raucous laughter, and offensive jokes that were interfering with my phone calls.
This morning, while I was taking a phone order, the same thing occurred.
I talked about it with [worker name] once again.
She said, "I should lighten up," as opposed to apologizing.
Here is a proof of the occurrence [sound recording].

4. State Desired Remedy

Write how your ability to work is affected by the actions of your coworkers.

List your responsibilities at work and your aim to fulfill them.

Describe how your coworker's activities are impeding your ability to achieve your goals.

Furthermore, express your gratitude to the employer for its assistance in putting an end to actions that are inappropriate for the workplace.


I've had to put my clients on hold multiple times to urge [worker name] to stop talking. Additionally, I've had to ask clients to repeat themselves since I couldn't hear them well.
I fear that his/her actions are damaging the company's reputation.
If you could let her know why this conduct needs to cease, I would appreciate it.

5. Edit and Proofread

Once you've finished writing, your email needs to be edited and proofread.

First, go over everything and strike out any sentences that were too sentimental, rude, or might have been expressed more succinctly.

Verify your spelling, grammar, and punctuation.

6. Send a Complaint Email to Your Employer

After you send an email of complaint to your employer, meeting with your manager to formally discuss the issue is the last step.

In case the employer is unable to address your issues make sure to write and address the HR department.

Additionally, it's important to avoid editing your email during the exchange, as altering facts at this stage could undermine your credibility and be detrimental to your position.

In case your resolution techniques are not solved and your work continues to be affected, ask for a transfer or resign if you have another job offer.
