Which act prohibits employment discrimination based on age?

The Age Discrimination Act is specifically designed to address and prohibit employment discrimination based on age. This legislation aims to ensure that individuals who are 40 years of age or older are protected from discrimination in hiring, promotion, termination, compensation, or any other condition of employment. It seeks to promote equal opportunity in the workplace, facilitating a fair environment regardless of age, thus helping to safeguard the rights of older workers.

The other acts mentioned do not specifically target age discrimination. The Civil Rights Act primarily addresses discrimination based on race, color, religion, sex, or national origin. The Equal Opportunity Act focuses on ensuring equal opportunity in various social and economic avenues but does not specifically address age discrimination. The Employment Rights Act mainly relates to rights and protections regarding employment conditions and employee entitlements, which is broader but does not directly pertain to age discrimination issues. Thus, the Age Discrimination Act is the most relevant piece of legislation in this context.
