If you were laid off, there are multiple laws you should know about. One of them is the
Older Workers Benefit Protection Act (OWBPA)
As part of the OWBPA, your employer must give you a document that has the job titles and ages of all laid off employees. The purpose of this disclosure is to discourage employers from selecting only older works for a layoff. Since this disclosure might indicate that mainly older workers were laid off, some employers fail to provide the disclosure
If your employer failed to provide you the disclosure required under the OWBPA, please search for OWBPA and lawyers to find a lawyer who specializes in employment law
Since this is a Federal law, it doesn't matter where the lawyer is located; the law applies, regardless of where you live
