The Sovereign Miners’ Coalition (SMC) — the first belt-wide workers’ organisation in the settled system, founded by the Tianshui Compact signed 13 October 2159 by delegates from 213 of the belt’s 247 independent stations. Convened by the strike committees coordinating work stoppages across the main belt since August 2159, it is co-chaired by Jason Bennett and Zhao Zihan; delegates colloquially call it the Belters Union. The Compact establishes unified strike protocols, mutual aid agreements, a dues structure, and a standing bargaining secretariat at Tianshui, with demands including mandatory registration of station workers, published standard contract terms, crew insurance against piracy losses, and inspection access to Vesta and Pallas. The UN Office of Legal Affairs is reviewing the demands and has offered space in Hygiea’s administrative galleries for the secretariat; no decision has been announced. By 2165 the Compact’s secretariat operates from Hygiea; on the announcement of the UN Strategic Fleet Command it reserved comment pending review of the command’s mandate.
