Control by the miner's union from 1952 to 1965 allowed the realization of revolutionary ideals—an open, achievement-based society following Western-urban patterns. Three modal categories are described: the part-time worker interested in cash to maximize ethnic values; the full-time, bicultural-bilingual miner balancing between Indian and non-Indian, switching codes according to context; and the committed member of the miner-worker class who has rejected his Indian heritage. Progress along this assimilation continuum is in terms of increasing commitment to union ideology and compartmentalization of ethnic values and behavior.enEthnic groupCultural assimilationIdeologySociologyContext (archaeology)Gender studiesPolitical scienceEthnologyAnthropologyarticle
