Plaintiff establishes prima facie case of age discrimination under ADEA by showing: (1) membership in protected class (58 years old), (2) qualification for the position, (3) adverse employment action (termination), and (4) replacement by younger worker.
The timing of termination during "workforce modernization" initiative creates inference of age-based discrimination.
Statistical evidence showing disproportionate impact on employees over 50 strengthens discrimination claim.
Documented performance reviews showing "exceeds expectations" ratings contradict employer's stated reason for termination.
Comparator evidence showing younger employees with similar or worse performance were retained.
Company emails using coded language like "new energy" and "fresh perspective" may indicate age bias.
Prohibits age discrimination against individuals 40 years or older in employment decisions.
Establishes the burden-shifting framework for discrimination cases.
Clarifies that plaintiff must prove age was the "but-for" cause of adverse action in ADEA cases.
Holds that plaintiff's prima facie case plus evidence of pretext can be sufficient to survive summary judgment.
