Unfortunately, people are still affected by age discrimination. Promotion, training, benefits and other areas of employment are situations in which a person can be discriminated against simply because of their age. Hence the phrase "age discrimination". Promotion is an area of employment that, more often than not, means a bigger salary, and more benefits, both of which the employer must pick up the tab for. It may be cheaper in the long run for an employer to promote a younger employee rather than an older one. This, however, is absolutely against the law. More specifically, against the language of the Age Discrimination in Employment Act (ADEA) which every employer must abide by if they want to do business in the United States.
