That is a sad ass resume.
First of all, most people looking for an entry level positon in manufacturing don't even need a resume. They usually just complete a job application. Second of all, if this person only has a high school education, highlighting the types of classes one took would be helpful. If they have college or other training outside of high school, that should be highlighted.
What kills me is when JWs put going out in service as volunteer work on their resume. This is only really helpful if you are looking for a door to door sales job...Kirby will love you. =)
I review about 100 to 200 resumes on a weekly basis, a lot of them are unsolicited resumes from job seeks with no real world experience. A lot of them (especially those looking to get into IT fields like pc techs and entry level helpdesk positions) usually put down their unpaid work, such as a computer lab assistant, or volunteering at the library, etc. A smart thing to put down.
Now, I don't think putting down work experience on a KH is a bad idea at all, especially if the job seeker is looking for manual labor. But as one poster said, everything put on a resume better be verifiable..some this candidate better make sure Brother In Charge of Roofing remembers who he is and has agreed to be used as a reference.
