Age discrimination refers to the unfair treatment of individuals based on their age, often affecting older adults in the workplace. This can manifest in various ways, such as being passed over for promotions, receiving lower pay, or facing difficulty in finding employment due to age-related biases. Laws like the Age Discrimination in Employment Act (ADEA) in the United States aim to protect workers aged 40 and older from such discrimination. Despite these protections, ageism can still persist in hiring practices and workplace cultures, impacting the opportunities available to older individuals.
