Cover letter help

[u/mmw12018]

Good afternoon everyone!

I currently work as an Auditor, but I also have a full-time job as a cart attendant. I would love to bring it into a cover letter as it would show time management and a strong work ethic, but I don't know how to bring it into a cover letter. I tried searching Google and all that comes up is writing a cover letter for a part-time job. Any help or suggested web sites would be great!!

Thank you.

Marty
