Most often, I recommend eliminating the historical work history on a resume.
If you look toward a functional resume, you can combine all of the transferrable skills in less space/text.
All you want the resume to do, is secure you an interview.
The problem is they require an application and work history.
Try to eliminate or combine some years by not listing exact months if that'll help streamline.
Include as far back as necessary to include the relevant transferrable experience.
No more then 10 years of work history is needed on this type of application. Most recruiters/HR people feel that stuff you did more then 10 years ago is not longer relevant.
Douglas, this is what I would say if you are working on Work history especially if you had many employers, make it simple and clean by listing your skills in bullet points, otherwise all of the wording will be overwhelming and they will probably ignore it.
Thank you everyone for your replies and feedback. I don't like providing work histories. But an application for a teaching position did request one. I went back as far as Dec. 1996. I kept it separate from my résumé. I'll be making the follow-up call on Monday morning. Thanks again to everyone. This is one of the things I love about the 48days community: everyone is so willing to help out. Blessings to all.
Folks are right 10 years is the way to go. But if you have a really unique work experience that pre-dates that, I think that is worthwhile to put on the resume or somehow sneak it in there or put it on the cover letter.
