Final answer:
Equal Opportunity complaints must be filed within six months after receiving a discriminatory paycheck, as mandated by the Lilly Ledbetter Fair Pay Act of 2009.
Step-by-step explanation:
Equal Opportunity complaints should typically be made within a certain timeframe after an offending incident. According to the Lilly Ledbetter Fair Pay Act of 2009, the period to file a complaint is extended to six months after receiving any discriminatory paycheck. This Act overturned a previous Supreme Court decision and applies to redress for pay discrimination based on factors such as race, religion, disability, or age. It's essential for individuals who experience discrimination to file their complaints within this statute of limitations to seek justice and remedy for the discriminatory practices they've faced.
