NC S484

Expands North Carolina's Workplace Violence Prevention laws to include "mass picketing" as a form of unlawful conduct, defined as picketing that obstructs ingress and egress to premises or public roadways through physical presence, vehicles, or other obstructions

Adds three new categories of unlawful conduct: hindering lawful work through mass picketing, unlawful threats, or force; obstructing entrances to places of employment; and interfering with public roads, highways, railways, or airports through mass picketing

Allows employers to seek civil no-contact orders against individuals engaged in unlawful conduct, with violations punishable as contempt of court resulting in fines or imprisonment

Explicitly exempts peaceful demonstrations, informational picketing, union organizing, and labor activity protected by the National Labor Relations Act (29 U.S.C. § 151) or the North Carolina Constitution from the law's coverage

Includes a severability clause ensuring remaining provisions stay in effect if any portion is invalidated by courts, and affirms the law does not restrict rights protected by state or federal constitutions
