I never thought 40 was old, not even was I was 20. Now that I've reached that age and beyond, I really can't understand why an employer would discriminate against anyone over 40, or for that matter, over any age. One's ability to do a job has nothing to do with how old he or she is. In my opinion the only thing age brings to a job is experience. There are employers who think of age as more than a number. They see it as a reason someone may not be able to do a job. They therefore choose not to hire certain job candidates or they pass over current employees for promotions. Those employees are breaking the law the Age Discrimination in Employment Act (ADEA) to be specific. Read Preventing Age Discrimination at Work to learn more about the Age Discrimination in Employment Act and how it protects workers who are 40 years of age and over.
