What does the Older Workers Benefit Protection Act (OWBPA) require from employers? Check all that apply. Employers must disclose the ages of both terminated and retained employees in layoff situations. Employers cannot lay off workers over the age of 40 unless they lay off an equal number of workers under the age of 40. If severance packages are offered to workers under 40, they must also be offered to workers who are over 40. Workers who are over 40 must be granted 45 days in which to consider accepting severance benefits and waiving their right to sue
