Anti-Union Activity
Conduct Screen Labor Rights
Documented pattern of suppressing worker organizing — union-busting campaigns, retaliatory firings of organizers, mandatory anti-union meetings (captive audience), hiring union avoidance consultants, or closing facilities in response to organizing. Same escalating threshold: one incident is alarming, two is very concerning, three or more independent incidents is dispositive. The test is active interference with workers' right to organize, not simply being non-union. Recency matters — reformed labor practices should be weighed. Distinct from working_conditions (the conditions themselves) and worker_exploitation (wage/hour violations).
