Many workers or job seekers over the age of 40 are subject to age discrimination. Many employers seek younger employees because of a perception that younger employees will work harder, learn faster and will accept lower wages. However, in discriminating against the older workforce, employers are not only breaking the law but are also missing out on some of the most experienced employees available. The Age Discrimination in Employment Act (ADEA) of 1967 specifically prevents employment discrimination against workers over the age of 40. The law also sets standards for pensions and benefits provided by employers. Employees or jobseekers who believe they have suffered age discrimination at work can file a complaint with the Equal Employment Opportunity Commission (EEOC) the federal agency which enforces legislation designed to prevent job discrimination of all types. The EEOC hears complaints and also files lawsuits where necessary on behalf of those who have suffered from employment discrimination. Since 1978, the ADEA has prohibited mandatory retirement ages in most cases.
