A: Yes, you can have too many jobs on a resume.

Without seeing your resume, I can't tell if this is a problem for you. But it's a problem for many who have been in the workforce for few decades. Jobs can pile up and by the time you're in your forties or fifties, a resume can read like The History of Capitalism. Sadly, most hiring officials don't have the time to read an historical tome -- at least not while they're trying to fill a critical position in their organization.

But you're correct, too, in saying that you want the resume to be truthful and accurate. The solution? Focus on the 2-3 positions most relevant to your objective (with any luck, they'll be the most recent positions), and minimize the balance of your work history. For those jobs most distant (beyond 10 or 15 years), or least appropriate to your current objective, consider...

... scrapping the job descriptions and just go with companies and titles, or
... consolidating multiple titles under the same companies, or
... replacing specific info with a 1-3 line summary of past experience.

Also consider leaving off the dates of employment for jobs that took place more than 15 or 20 years ago. Yes, truth and accuracy are important, but your resume is not a biography. Rather, it's a summary of job experience and education relevant to your objective.

Note: If you're having trouble identifying which are the most relevant positions on which to focus, or exactly how to minimize those early years of your work history, a professional resume writer can likely be of help. That's the type of thing they do, day in and day out. To find a good one, visit our home page to see mini-reviews of some of the more popular resume writers on the web.
