Now that you know what a cover letter should look like, let's go into further detail on how to tailor your cover letter to your assembly line worker role.

PRO TIP

If you can't find the hiring manager's name, you can address your cover letter with “Dear Hiring Manager.“ but never use the generic “To Whom It May Concern.“

STEP 2

Introduce yourself in the opening paragraph

The way you introduce yourself to hiring managers in your cover letter's opening paragraph will set the tone for the rest of your letter. Stand out by mentioning key skills and qualifications, and state your interest in the particular assembly line worker position.

As a machine operator with over 5 years of experience in the manufacturing sector, I am excited to apply for the assembly line worker position at Precision Manufacturing Inc. My expertise in operational efficiency has prepared me well, as demonstrated by reducing equipment downtime by 30% last year through proactive maintenance and troubleshooting. I am eager to contribute my skills and dedication to your team.

PRO TIP

If a current employee has referred you for the position, mentioning it here can make a big difference. Check out our article on referral cover letter openings for examples of how to do this effectively.

STEP 3

Share relevant achievements in the body paragraph

Your cover letter's body paragraph will comprise the bulk of your document and should focus on quantifiable achievements and additional key skills. You can also get more personal with this section and show employers your passion for the job or career goals.

Strong body paragraph example:

With experience as an assembly line worker, I consistently optimized production processes to increase efficiency by 30%, demonstrating a keen eye for detail and problem-solving skills. My ability to collaborate effectively with teammates ensured seamless operations, reducing downtime by 25%. I excel at adhering to strict safety standards, maintaining a zero-incident record during my tenure, which underscores my commitment to workplace safety and productivity enhancements on the assembly line.

Cross icon

Weak body paragraph example:

I am interested in the assembly line worker position because I need employment and believe I could perform the tasks. I don't have much experience in manufacturing, but I learn quickly. I haven't worked with machinery, but I'm willing to try. I hope I can succeed if I am given a chance to work on it.

STEP 4

Finish by encouraging next steps

The closing paragraph will be the final section of your assembly line worker cover letter. Use this section to share any final skills or qualifications you possess and state your interest in a future interview. Go for confident tone and proper sign-off before signing your name.
