In this question about gaps in employment one answer suggested mentioning on your resume if you were part of a mass-layoff:
being part of a large layoff should be noted in the resume. If your division lost 1,500 jobs, and you were in that pool, then note it: "Was included in a large layoff" or something similar.
Having been through similar circumstances, I've never mentioned such on my resume. I'm wondering if this is sound advice or risky. In particular, I'm most interested in the perspective of those who review resumes and select which candidates to interview. Will mentioning a mass-layoff help or hinder my chances of getting interviews? Or does it simply depend on the interviewer whether it would leave a positive or negative taste in their mouth? Are there general pros and cons to consider before deciding whether such should be mentioned on the resume?
