Supervisor Cover Letter Examples (Production, Customer Service, Maintenance)

Cover letters, also referred to as a letter of introduction, are often sent as a medium of introduction. It is usually sent accompanying other documents such as a resume. Regardless of the position you are applying for, the organization will always want to see your relevant work history and skills according to the job when sending your cover letter. Properly tailoring your cover letter to highlight your relevant achievements clearly can enable you to stand out and get your dream job. Whether you are applying for a customer service supervisor, maintenance, production, or warehouse supervisor, this article will help guide you through all you need to know to write an effective supervisor cover letter.

Things to do Before Writing Your Supervisor Cover Letter

Find out whom to address the letter to

Try as much as possible to avoid addressing your letter “To whom it may concern.” Find out the name of the person who will read your letter. This might take some of your efforts, but it is worth it.

If the job opening has been listed in an advert, it will probably name the person the application is supposed to address. If not, make an effort to contact the employer or advertiser and ask them to whom you should send the application.

Find out more about the job

When trying to find out whom to address the letter to, you can also try to ask a few questions to properly tailor your letter to the job you are applying for. You could ask:

  • Can you tell me more about the type of person you are looking to fill the position?
  • Does the job involve working as a team?
  • Whom will I be reporting to if I get the job?

Make sure to note down all the answers as they will come in handy when writing your cover letter.

Find out more about the company

To help you properly tailor your cover letter for the position that you are applying for, here are some basic tips to use:

  • If you don’t know the basic information about the company, look for the information online
  • If the company has a website, make sure that you visit it and pay more attention to the “About Us” page.
  • If the company name or the recipient’s name isn’t included in the advert, call the recruitment agency or the advertiser and ask who the employer is. 

How to Write an Effective Supervisor Cover Letter

All cover letters should convey all the necessary information clearly and succinctly. Here is what you should include in your supervisor cover letter:

Your Name and Contact Details

Write your name and contact details at the very top of the cover letter. You don’t have to include your postal address, but you have to include your email and phone number. Remember to use a professional email in the cover letter.

Their Name and Contact Details

Just below your name and contact details, you should include:

  • The name of the recipient of the letter
  • The name of their company and their position at the company
  • Their contact details

In most cases, all these details are usually included in the job advert or on the company’s website; however, if you find it hard to obtain such information, you should contact the company and ask to whom you should address your application. Try to avoid using the generic “To whom it may concern.”

The Position That you are Applying For

At the start of your supervisor cover letter, you need to state the job you are applying for.

You can do this in a simple sentence, for example, “Re: Application for Warehouse Supervisor.” Alternatively, you can also do this in the opening paragraph; for example, “I am writing to apply for the recently advertised warehouse supervisor position at your company.”

A List of your Relevant Skills

Don’t just list all your skills for the sake of writing; make sure that the skills you are listing in your cover letter fit the job that you are applying for. Write a summary of your skills/experience. You can use a short bullet list.

If you are writing the letter in response to a job advert that you may have seen, there may be a position description that lists all the essential skills and experiences that the job requires. It may also include a list of the “desirable” skills and experience. When writing your cover letter, make sure that you respond to as many items as you possibly can on the desirable skills and experience list.

A Summary of Why You are the Best Candidate for the Position

After correctly listing your skills and experience, you should continue to explain why the skills you have listed make you the best fit for the position that you are applying for. For example, you can write that “My ability to get along with anyone makes me ideally suited for this position.”

Speak Their Language

Using the type of language as people working for the organization shows that you are conversant with the industry’s culture or the field that the employer works in.

Find out more about the company you are applying to, how they talk about themselves, what they do, and any information that can help you gain a competitive edge when writing your cover letter.

Ask Them to Contact You

Conclude your cover letter by asking them to read your resume and contact you to set up an interview. You can write something like, “I have attached a copy of my resume. I look forward to hearing from you about this job.”

Things to Avoid in Your Letter

There are some things that you should try as much as possible to avoid when writing your cover letter. These include:

  • Typos and Mistakes

Always double check your work. You can even get someone else to read it and help you point out the mistakes in your letter.

  • Including your whole resume in the cover letter

Don’t just cut and paste your resume into your cover letter. Try to rewrite the information in your resume, rather than just repeating it. Keep the cover letter short and refer them to your resume to get more information.

  • Using “I” too much

Try as much as possible to avoid overusing phrases like “I believe,” “I have,” and “I am.” Keep in mind that it is not about you – It is about how you will benefit the employer.

  • Mentioning your other job applications

When you are looking for work, you are probably applying for more than one job at a time. However, it is best not to mention the other jobs that you may have applied for. Your letter should only inform the employer that you are ready for the job and that you really want the position.
