How the algorithm turned leave into liability
The structural flaw at the center of this lawsuit is not that Meta's AI was programmed to target people on leave - it is that the metrics chosen made leave mathematically indistinguishable from disengagement. According to the complaint, Meta's layoff selection drew on keystroke activity, browser history, AI token-usage dashboards, and ratings for being 'AI-native' - all measures that, by definition, require physical presence at a keyboard to accumulate. [1]An employee on parental or medical leave cannot log keystrokes, consume AI tokens, or rack up 'AI-native' ratings during their absence. The system, as alleged, 'failed to distinguish employees' leave from lack of engagement,' and at least one director was warned that absences could be 'held against him' during the layoff evaluation. [2]This is the crux of the disparate impact argument: no explicit intent to discriminate is required. A facially neutral productivity system that cannot accommodate absence will statistically burden any class of workers who take protected leave - women on maternity leave, workers with disabilities, employees recovering from illness. The complaint states the AI scoring metrics 'by design, cannot be accumulated by an employee who is on protected medical or family leave, or whose output is reduced by a disability.' [3]Critically, the lawsuit also alleges Meta 'did not pause the system for the individualized, leave- and accommodation-neutral review that the law requires,' and that some plaintiffs were actively discouraged from taking FMLA leave. [4]The result is a system where the path of least resistance - staying on leave as entitled by law - became a career liability.
